Drug Overdosing: How to Avoid Medication
Side Effects
Drug side effects are the fourth leading cause of death in the United
States. According to an article published in the Journal of the American
Medical Association (JAMA) (Lazarou et al. 1998), about 106,000 Americans
die and 2,000,000 suffer from severe reactions every year from drugs prescribed
in hospitals. The information presented in this protocol was written to
enable you to reduce your risk of adverse drug reactions, while saving
significant dollars on the cost of your prescription medications. In addition,
it will provide you with a greater sense of control over your future good
health and help you to interact more confidently with your physician.
The statistics mentioned above understate the true magnitude of the problem,
since people often die from adverse drug reactions outside the hospital.
There are also many deaths that occur in hospitals caused by drugs prescribed
outside the hospital. For example, some prescription drugs deplete calcium
from bones, which causes elderly people to suffer fractures, which leads
to their hospitalization. In the hospital, these people often develop
pneumonia, vascular blood clots, sepsis, or some other illness that kills
them. The death certificate may list "pneumonia" as the cause
of death, but it was the inappropriate prescribing of the bone-depleting
drug in the first place that caused the fracture, which necessitated the
hospital confinement that led to pneumonia.
An examination of the data beyond that recorded on death certificates
reveals a shocking number of deaths related to inappropriate drug prescribing.
Even when a drug like Rezulin (Sparano et al. 1998) was withdrawn because
too many people were dying from liver failure (Watkins et al. 1998; Fukano
et al. 2000), it was estimated that only one out of ten deaths caused
by Rezulin was ever attributed to the drug (LA Times 2000).
WHAT MAKES PRESCRIPTION
DRUGS SO DANGEROUS?
All drugs have the potential to cause side effects by themselves, or
through interaction with other drugs. This is one reason why more people
are turning to natural therapies that have proven track records of safety.
In order for pharmaceutical companies to earn a profit, they must develop
drugs that are potent enough to patent and can be approved by the FDA.
To gain FDA approval, these drugs must demonstrate an acceptable safety
profile. However, the safe dose of potent drugs can vary considerably
among individuals. What is safe for some people can be a lethal overdose
for others. Yet doctors and drug companies usually recommend the same
dose for everyone, even though lower doses of many prescription drugs
can achieve the same beneficial effects, while dramatically reducing side
effect risk and the cost of the medications.
Consider the cholesterol-lowering drug Zocor, for example. The recommended
starting dose is 20 mg, which has been shown to lower LDL cholesterol
by an average of 38%. Scientific studies show, however, that 5 to 10 mg
of Zocor works almost as well as 20 mg. This lower dose could reduce the
risk of side effects by as much as fourfold.
If your LDL-cholesterol level is 130 (mg/dL) and your objective is to
reduce it to under 100, just 5 mg a day of Zocor should accomplish this.
Yet, the typical starting dose of Zocor is 20 mg, and some doctors even
start as high as 40 mg. . . eight times higher than the dose needed by
many people!
New studies indicate that side effects (especially muscle aches) from
statin drugs such as Zocor are more common than originally thought. When
a person is prescribed 20 mg of Zocor, and encounters toxic side effects,
the patient often abandons the drug. Yet, if only 5 mg of Zocor were taken,
the odds of encountering side effects would be reduced and the therapeutic
target (LDL-cholesterol under 100) might be easily achieved.
It's not just Zocor that is often overdosed. The number one statin drug
sold in the United States is Lipitor, which is typically prescribed in
doses of 10 mg and higher. There are studies, however, showing that as
little as 2.5 mg a day is effective for many people.
If you are a statin drug user, have your blood tested to make sure your
total cholesterol is not below 180 mg/dL. Cholesterol levels below 180
(mg/dL) can increase your risk of cerebral hemorrhage and other lethal
diseases. Scientific studies show that the optimal total cholesterol range
is 180-220, while LDL-cholesterol should be under 100 and beneficial HDL-cholesterol
over 50. Some statin drug users drop their total cholesterol below 150.
If these people had taken a lower dose of the drug, they would probably
have adequately lowered their cholesterol levels, reduced their toxicity
risk, and saved a good deal of money. (See below on how to save money
on certain prescription medications.)
Too Much Prozac
Prozac has received considerable media attention for allegedly causing
serious psychological disturbances. Attorneys have blamed Prozac for all
kinds of criminal behaviors, and anecdotal reports abound about the adverse
effects some people experience on the standard (20 mg) daily dose of this
popular antidepressant.
When Prozac was introduced, it came only in 20-mg capsules, and all
patients were started at this dose. While Prozac helped most people, it
caused serious side effects in others. Among the side effects caused by
Prozac are headache, nausea, irritability, sexual dysfunction (impaired
orgasm, reduced libido), low energy, dry mouth, tremor, anxiety, and insomnia.
A study published before Prozac was approved showed that a daily dose
of 5 mg of Prozac helped 54% of patients, while 20 mg helped 64%. In other
words, administering four times the 5-mg dose only helped 10% more people!
Some doctors have found that lower doses of Prozac produce antidepressant
benefits without causing side effects, yet the Physician's Desk Reference
(PDR) and the drug's package insert still recommend 20 mg as a starting
dose.
While overdosing on Prozac can cause serious psychological side effects,
other antidepressants like Elavil can be lethal when taken in too high
doses. The PDR still advises an initial dose of 75 mg for Elavil (amitriptyline)
followed by gradually higher doses. Yet 10 to 25 mg of Elavil is enough
to treat mild depression or pain syndromes. Too much Elavil can cause
irreversible AV node block in the heart, leading to fatal arrhythmia.
Antidepressant drugs are often prescribed in higher-than-needed doses,
and the ensuing side effects cause many patients to abandon them altogether.
An Epidemic of Overdosing
Later in this chapter, you will see how drug companies, physicians, and
the FDA are all culpable in overdosing Americans with dangerous drugs.
The chapter also explains the toxic mechanisms involved when too much
of a drug is consumed, along with newly identified side effects of popular
drugs. Of practical value are charts showing lower doses of the most popular
prescription drugs, how to determine if you should start off at a lower
dose, and how to avoid lethal drug interactions.
This chapter exposes today's flawed system of drug regulation. Prominent
scientists accuse the FDA of failing to protect the American consumer
against the drug companies. The FDA claims it is protecting Americans
against dangerous drugs, yet the statistics show an epidemic of drug-induced
injury and death.
Too many consumers unknowingly overdose on their prescription drugs.
When unpleasant side effects develop, people often stop taking the drug
completely, even though a lower dose might be safe and effective.
More than 100,000 Americans die every year from prescription drug side
effects. In many cases, the drug-induced death could have been avoided
if a lower dose had been used.
SAVING LIVES
Chronic overdosing of prescription drugs is one of the greatest health
hazards Americans face. How can the medical establishment ignore something
so obvious? Unfortunately, obvious ways of improving patient care are
routinely overlooked by medical professionals. Today's leading causes
of disability and death are ignorance and apathy in applying proven scientific
methods of preventing and treating disease.
The information presented in this chapter will enable you to save hundreds
of dollars a year on prescription drugs, while reducing your risk of debilitating
or lethal side effects.
Save Money With Alternate Day Rather
than Daily Dosing
Some drugs you are taking every day may work as well if you take them
every other day. In a study published in the American Heart Journal
(Matalka et al. 2002), a comparison was done using the cholesterol-lowering
drug Lipitor every day or every other (alternate) day. The findings showed
that alternate-day dosing was comparable to dosing every day.
The patients were started at 10 mg and their dose increased to 20 mg
if needed. The every day dosing schedule required a mean of 12 mg/day
of Lipitor to sufficiently lower cholesterol, whereas the alternate day
group only required a mean 9 mg/day to achieve similar effects. The doctors
concluded the study abstract by stating:
"these results suggest that the alternate-day administration
of atorvastatin (Lipitor) can produce a reduction in LDL-C comparable
to that of daily administration in patients with hypercholesterolemia,
and yet provide some cost savings."
What was not revealed in this study was the enormous amount of the cost
savings. Life Extension has calculated the exact amount one could save
by switching to alternate-day dosing. Here are the numbers:
- The cost of taking 10 mg of Lipitor every day is about $60.00 a month.
- The cost of taking 10 mg of Lipitor every other day is only $30.00
a month.
- If 20 mg of Lipitor is needed every other day, the cost of 15 20-mg
tablets comes out to about $44.00 a month.
Armed with this knowledge, the Lipitor consumer can save 50% ($30.00
each month) if they find they need only 10 mg of Lipitor every other day.
If 20 mg of Lipitor is needed every other day, the consumer saves 26%
($16.00 each month).
Anyone contemplating changing their dosing schedule of any drug should
notify their physician and verify that the changed dose is working. In
the case of Lipitor, one would want to check LDL, HDL, C-reactive protein
and total cholesterol blood levels within 45 days of changing the dose.
While "statin" drugs like Lipitor are taken primarily to lower
cholesterol, a side benefit is that they also lower the more dangerous
C-reactive protein. New studies confirm that C-reactive protein is a greater
risk factor for heart attack and stroke than is cholesterol.
Many drugs (such as anti-hypertensives) absolutely have to be taken
every day or even several times throughout the day. Alternate-day dosing
should not be attempted with any medication without physician approval.
Save Money By Dividing Doses
Many prescription drugs do not come in the lower doses that are optimal
for many patients. In these cases, the tablets have to be split or capsules
opened in order to obtain the desired dose. While this is somewhat inconvenient,
the cost savings can be substantial.
Zocor is one drug that comes in a wide range of doses. Here are the
typical prices in the United States for 100 tablets of each available
dose of Zocor:
- 5 mg $171.87
- 10 mg $221.78
- 20 mg $371.00
- 40 mg $390.00
- 80 mg $345.00
For the many Zocor users who need only 5 mg a day (instead of 20 mg),
the savings are 53% if one switches from the 20-mg dose to the 5-mg dose.
For those who use a pill-splitter to break 20-mg tablets into four doses,
the savings are 75%. Information about pill splitting devices appears
later in this chapter.
It is interesting to note that in today's upside-down drug pricing environment,
80-mg Zocor tablets sometimes cost less than 40-mg tablets. If you don't
want to pay artificially inflated prices for prescription drugs, you can
order from Internet pharmacies in Canada. A bottle of 100 20-mg Zocor
tablets that costs $371.00 in the United States costs only $192.12 in
Canada, a 48% savings. A bottle containing 100 5-mg tablets of Zocor costs
$171.87 in the United States, but only $119.00 in Canada, a 30% savings.
That means if you buy 20-mg Zocor tablets in Canada and split them into
four doses (5 mg each), you can save 86%. Not everyone can get by with
only 5 mg a day of Zocor, but as shown in this chapter, many individuals
are overdosing on statin and other drugs and can obtain better results
by reducing their daily dose.
MEDICATIONS SIDE EFFECTS:
WHY THEY OCCUR AND HOW TO PREVENT THEM
by Jay Cohen, M.D.
Prescription drugs help millions of people. Still, most people don't
like taking drugs, although many of us ultimately need to. This section
discusses how you can get the treatment you need while minimizing the
risks.
Mainstream medicine's record on preventing medication side effects is
poor. A 1998 article in the Journal of the American Medical Association
(JAMA) defined the scope of the problem: 106,000 deaths and 2,000,000
severe reactions from medications annually in U.S. hospitals, making side
effects the fourth leading cause of death in America (Lazarou et al. 1998).
These numbers aren't new. The side effect problem has continued for decades
and persists unrecognized by many doctors and authorities.
But patients understand. Patients' first concern about medications is
safety. They know intuitively that, as a leading drug reference states,
"Any drug, no matter how trivial its therapeutic actions, has the
potential to do harm" (Gilman et al. 1990).
How can you maximize safety while getting the treatment you need? There
are ways that are in accordance with scientific principles and proven
by medical studies, yet routinely ignored by drug companies, the FDA,
and doctors.
The First Key to Avoiding Side
Effects
Side effects occur because most drugs aren't specific in their actions.
We may call a drug an "anti-inflammatory" or "antidepressant,"
but medications don't just go to the cells involved in these problems.
They go to most of the cells of our bodies, which can provoke undesirable
effects. Thus, an anti-inflammatory may reduce your joint pain, but it
may also cause stomach bleeding, kidney failure, or anxiety. An antidepressant
can improve mood but can also cause insomnia, nausea, weight gain, or
diminished sex drive.
Most of these unintended effects--side effects--are dose-related. You
see the same phenomenon every day with alcohol and coffee. In moderate
amounts, they cause few problems. But at excessive doses, coffee causes
edginess and insomnia, and alcohol impairs thinking and coordination.
The same is true with medications. Indeed, in the 1998 JAMA study cited
above, 76.2% of all side effects were dose-related. Melmon and Morrelli's
Clinical Pharmacology places the number at 75% to 85% (Melmon
et al. 1993). The number may be higher, because many drug interactions
are also dose-related. When people take multiple drugs, higher doses cause
more adverse interactions than lower doses. Whatever the actual number,
the first key to avoiding side effects is this: Most side effects are
dose-related. Hence, the problem isn't the drug itself, but a dose that's
too strong for you. Thus, the best way to avoid side effects is to use
the lowest dose that works. Excessive dosing merely increases risks.
The Second Key: Individual Variation
Why do side effects occur in some people but not in others? Because people
vary tremendously in their sensitivities to medications, just as they
do to alcohol and coffee.
The American Medical Association states that the difference in people's
response to a specific drug can vary "4- to 40-fold" (AMA 1994).
With such variability, it isn't surprising that some people can drink
a pot of coffee without problems while others can't handle a cup. Similarly,
it isn't surprising that some people need 80 mg of the antidepressant
Prozac or the cholesterol-lowering drug Lipitor, while others need just
2.5 mg.
Individual Variation with Medications
Isn't the Exception; It's the Rule
The basis of individual variation is well known. People differ greatly
in how they absorb, metabolize, and eliminate drugs. The new science of
pharmacogenetics has revealed wide variations in the efficiency of people's
liver enzymes in processing drugs. People also differ in the sensitivity
of their tissues to medication effects. These factors change with age,
and many people become more sensitive as they get older.
Some people are sensitive from the start. Indications are that about
10% of people are highly sensitive to medications. This is called a general
medication sensitivity. Some doctors dismiss such patients, but these
people are real enough. Often they are "poor metabolizers" with
inefficient liver enzymes that are genetically determined. With standard
doses, they develop high blood levels of medication that provoke side
effects. Such people need exceedingly low doses.
Because of the great variability between people, it is essential for
drug doses to be tailored to each person's needs. This is called precision
prescribing. Doctors already practice this with a few drugs--digoxin,
insulin, thyroid drugs--but not with most drugs. Many drugs are prescribed
one-size-fits-all or at doses that are identical for young and old, big
and small, healthy or taking six other drugs at the same time. The failure
to match drug doses to individual needs underlies the high incidence of
side effects.
Creating a Side Effect Epidemic
Drug companies and the FDA routinely ignore the wide differences in people's
drug tolerances and the fact that most side effects are dose-related.
Doctors, accepting drug company dosage guidelines uncritically, don't
think twice about prescribing the same doses of powerful drugs to young
and old, big and small, healthy and frail. They ignore patients with long
histories of medication reactions. "Cookbook dosing" is the
rule, and an epidemic of side effects is the result.
Even when studies show that half- and quarter-doses are effective, the
data are ignored and dosing is one-size-fits-all. Even when studies show
that women or the elderly respond to lower doses, they get the same higher
doses as younger, larger men. Something is very wrong when Shaquille O'Neal,
Ally McBeal, and Grandma Moses are getting the exact same doses of potent
drugs, yet this is exactly how many drugs are prescribed.
"To think that the same dose will do the same thing to all patients
is absurd," says Dr. Raymond Woosley, Vice President of Health Services
at the University of Arizona. "Patients need to be titrated, starting
with the lowest possible dose that could have the desired effect"
(Grady 1999).
Experts everywhere agree with him (Table 1), but that's not how it's
done today. The side effect epidemic isn't caused by a few bad drugs,
but by bad dosing methods with many drugs.

is essential. |

LISTENING TO PROZAC
When I began treating patients in 1970, I quickly noticed how differently
people responded to medications and began adjusting doses accordingly.
Although this occurred with every drug I used, I didn't realize the depth
of the problem until Prozac arrived in 1988.
As I did with all new drugs, I waited awhile before prescribing Prozac.
New drugs, like new model cars, often manifest unexpected problems. But
I heard only good things about Prozac, so I began prescribing it. I saw
two distinct patterns. Half of my patients did extremely well. Prozac
was clearly a breakthrough drug, far better than any earlier antidepressant.
But the other half of my patients had side effects, some severe. One
woman became so agitated it incapacitated her. Another became completely
psychotic after just three Prozac doses. The problem? The recommended,
one-size-fits-all initial dose, 20 mg, was too strong. I would have started
patients with lower doses, but Prozac was marketed in only one size, a
20-mg capsule. After these reactions occurred, I had patients open the
capsules, mix the powder in juice and start lower. Most did fine at 5
mg to 10 mg daily, and the severe, dose-related reactions ceased.
Meanwhile, troubled by the reactions I saw, I searched the medical literature
for explanations. I found more than I anticipated. A study published before
Prozac's approval showed that just 5 mg helped 54% of patients, while
20 mg--the recommended dose--helped 64% (Wernicke et al. 1988). In other
words, quadrupling the dose only improved efficacy 10%. To me, this meant
that 5 mg was a reasonable starting dose, yet doctors were told to start
everyone at 20 mg, even the 54% who needed only 5 mg! I was shocked and
appalled.
Meanwhile, other doctors began reporting severe reactions to Prozac
and that lower doses worked better (Table 2). Yet today, the standard
starting dose of Prozac remains 20 mg, and there's still scant information
in the package insert or Physicians' Desk Reference (PDR) about the effectiveness
of the 5-mg dose (Physicians' Desk Reference 2003). Prozac and other selective
serotonin reuptake inhibitors (SSRIs) continue to cause high incidences
of dose-related side effects such as headaches, nausea, weight gain, irritability,
sexual dysfunctions (impaired orgasm, reduced libido), low energy, dry
mouth, and tremor. Insomnia or anxiety occur frequently, too, which doctors
handle not by reducing the dose, but by adding a dependency-causing sleep
or anxiety remedy.
Dosage Problems with Other Antidepressants
Doctors follow the guidelines in the drug company-written PDR. The PDR
still advises 75 mg initially for Elavil (amitriptyline), yet 10 mg or
25 mg is frequently enough for mild depressions or pain syndromes. Effexor
is recommended at 75 mg, but 37.5 mg or 50 mg often is enough initially.
Zoloft is recommended at 50 mg, but 25 mg works well for many mild depressions.
Serzone is recommended at 100 mg twice-daily, but 50 mg once or twice
daily is usually plenty initially.
| Table 2: Low-Dose Prozac |
| Studies before and shortly
after Prozac's approval revealed that 5 mg--one-quarter the standard
20-mg initial dose--was highly effective and less toxic for many people.
|
| J. Clin. Psychopharmacol. (Schatzberg et al. 1987) |
"Clinically, we have observed fluoxetine (Prozac) to be effective
over a wide range with many patients requiring very low dosages..." |
| Psychopharmacol. Bull. (Wernicke et al. 1988) |
5 mg helped 54% with major depression; 20 mg helped 64%. Fewer
adverse effects with the 5 mg dose. Conclusion: "No lower limit
for an effective dose of this potent serotonin uptake inhibitor has
been demonstrated in moderately depressed outpatients." |
| J Clin. Psychiatry (Salzman 1990) |
"A single daily dose of 20 mg may overmedicate some older
depressed patients. Experienced geriatric clinicians sometimes advise
older patients to open the capsule and sprinkle small amounts of fluoxetine
in a flavored beverage such as orange juice. Alternatively, the contents
of an entire capsule may be dissolved in a beverage, but only a part
(such as one quarter or one half) is consumed each day." |
| J Clin. Psychiatry (Schatzberg 1991) |
"Today, it is clear, however, that the precept of pushing
the depressed patient quickly to a high dosage of antidepressant medication
is not the optimal strategy for serotonergic agents. `Start low and
stay low' may be the new watchword, particularly with... compounds
such as fluoxetine [Prozac]." |
| J Clin. Psychiatry (Cain 1992) |
"In the 5 mg, 20 mg, and 40 mg fixed-dose study, there were
no differences in effectiveness between the active treatment groups,
all of which were superior to placebo. Side effect dropouts increased
significantly with dosage....With endpoint analysis, numerically,
5 mg/day outperformed 40 mg/day which outperformed 20 mg/day...These
data point to 5 mg/day as optimal, although there is no evidence that
doses below 5 mg/day are not equally effective." |
| J Clin. Psychiatry (Louie et al. 1993) |
"We conclude that starting fluoxetine at doses lower than 20
mg is a useful strategy because of the substantial fraction of patients
who cannot tolerate a 20-mg dose but appear to benefit from lower
doses.... Patients often benefitted clinically from treatment at lower
doses, and failure to tolerate 20 mg/day of fluoxetine should not
be taken as evidence that the agent cannot be used efficaciously in
these patients." |
| Conn's Current Therapy (Rakel 1993) |
"Many patients respond to the starting dose of 20 mg per day,
but a substantial proportion need lower doses (e.g., 2.5 to 10/day)" |
| N. Engl. J. Med. (Gram 1994) |
"The results of three dose-effect studies... [demonstrated
that] a dose of 5 mg per day was effective as any of the higher doses."
|
Similar strategies apply to Paxil, Wellbutrin, Celexa, Norpramin, Pamelor,
imipramine, doxepin and just about every other antidepressant. "The
sales representatives for most antidepressants are now giving out sample
packs starting with half-strength doses," Dr. Anthony Weisenberger,
a top psychopharmacologist, recently said. "They lose so many sales
because patients get side effects and quit treatment, the drug companies
have finally caught on that the dose makes a big difference."
Why is this happening with drug after drug? One reason is that the standard
doses of antidepressants are based on studies of major depression--a severe
disorder that requires strong treatment. In contrast, the great majority
of office patients with depression have mild disorders. Yet, no distinction
is made about treating mild and severe disorders in the dosage guidelines
of most antidepressants, so doctors prescribe the same doses to everyone.
DRUGS FOR ELEVATED
CHOLESTEROL AND C-REACTIVE PROTEIN
The statins--Lipitor, Zocor, Pravachol, Mevacor, Lescol--were the best-selling
group of drugs in America in 2001. There's no doubt that statins help
millions by reducing heart attacks, strokes and overall cardiac mortality.
But statins harm thousands, perhaps millions more, often unnecessarily.
Duane Graveline's first dose of Lipitor caused amnesia "so severe
that I landed in the emergency room of a hospital near my Vermont home.
I didn't remember any of it." Dr. Graveline, a retired family doctor,
flight surgeon and astronaut (www.spacedoc.net), was perplexed. After
all, he wasn't usually sensitive to medications, and he'd taken only 10
mg, the lowest dose recommended and marketed by the manufacturer.
Yet, 10 mg of Lipitor is very strong, much stronger than many people
need. It was much stronger than Dr. Graveline needed, because he needed
only 2.5 mg of Lipitor--75% less medication than he got. How do we know?
Experts advise doctors to select statin doses based on the reduction in
LDL-C (the bad, low-density-lipoprotein cholesterol) that each person
needs (NCEP 2001). Ten milligrams of Lipitor reduces LDL-C 39%, a strong
response needed by cardiac patients and people with severely elevated
cholesterol.
But most people with high cholesterol have mild-to-moderate elevations
and no cardiac history, and they require only 20% to 30% reductions in
LDL-C. This can be attained with only 2.5 mg or 5 mg of Lipitor (Nowrocki
et al. 1995; Wolffenbuttel et al. 1998; Bakker-Arkema et al. 1997; Cilla
et al. 1996). Dr. Graveline required a 25% reduction in LDL-C and should
have been started at 2.5 mg. Yet, there's no information about 2.5 or
5 mg of Lipitor in the package insert or PDR and no pills in these doses,
so doctors start everyone at 10 mg, or even 20 mg or 40 mg.
Excessive Statin Doses, Unnecessary
Side Effects
Dr. Graveline received 400% more medication than he needed and got a major
dose-related side effect because of it. This is a common story. Cognitive
and memory problems, sometimes severe and long lasting, occur far more
often with statins than doctors recognize. Muscle pain and abdominal discomfort
occur frequently. All of these are dose-related.
Liver disorders occur in 1% of patients taking statins. With statins
now recommended for 35 million Americans, that's 350,000 people with liver
problems, which include liver toxicity and, rarely, death. Dr. W. C. Roberts,
the editor-in-chief of the American Journal of Cardiology, states,
"With each doubling of the dose, the frequency of liver enzyme elevations
also doubles" (Roberts 1997). Liver enzyme elevations signify liver
injury. So if you get 10 mg of Lipitor when you only need 2.5 mg, your
risk of liver injury is also quadrupled.
Lipitor is the best-selling drug In America. In 2001, patients filled
more than 57 million prescriptions for Lipitor, and sales are skyrocketing.
Zocor, the third-best-selling drug, presents the same dose problems as
Lipitor. Zocor's standard starting dose, 20 mg, reduces LDL-C 38%. Many
people need only 10 mg or even 5 mg, which reduce LDL-C 30% and 26%, respectively
(Physicians' Desk Reference 2003). If the standard doses of such widely
advertised, top-selling drugs, are so strong, how can we rely on the standard
doses of any drug?
More is not always better with medications. Some people do need strong
statins. Often, however, a milder drug that works is preferable to a potent
one. "Pravachol is the statin drug I prescribe most often because
it is the weakest of the bunch," Dr. Stephen Sinatra writes. "We
don't need to prescribe large doses of these statins to get results"
(Sinatra 2002). People with mild cholesterol elevations usually don't
need high potency doses of Lipitor and Zocor, but doctors prescribe them
anyway even when milder statins--Pravachol, Mevacor, Lescol--would do
(Table 3).

Even with the latter drugs, lower doses work for millions of people.
A study conducted by the manufacturer of Pravachol showed that just 10
mg was sufficient for 83% of people with moderate cholesterol elevations
(Bristol-Myers Squibb 2000). Four studies by Mevacor's manufacturer showed
that just 10 mg, with diet counseling, reduced cholesterol satisfactorily
in 69% to 75% of subjects. Indeed, the LDL-C of 17% to 26% of subjects
dropped below 100 mg/dL, the level sought for people with cardiac disease
(FDA 2000). This isn't surprising; some people get much better LDL-C reductions
than the averages in the PDR.
Treating Elevated C-Reactive Protein
Half of all cardiac deaths occur in people with normal cholesterol levels.
Something else is going on. New studies suggest that elevated C-reactive
protein (CRP), a test for internal inflammation, may be as important an
indicator of cardiovascular risk as cholesterol levels, because inflammation
in artery walls plays an important role in the development of atherosclerosis
(Ridker et al. 2002).
Mainstream doctors are already prescribing statins to people with elevated
C-reactive protein (CRP) levels, often at doses that are unnecessarily
high. Meanwhile, other, safer methods such as omega-3 oils, which are
known to reduce inflammation and cardiac risk (Carroll et al. 2002; GISSI-Prevenzione
Investigators 1999), are being overlooked.
DRUGS FOR HIGH BLOOD
PRESSURE
Fifty million Americans have high blood pressure (hypertension), and
90% of us will ultimately develop this potentially deadly disease as we
age. Hypertension is a particularly vicious disease, a silent destroyer
of blood vessels that causes heart attacks, strokes, kidney disease, peripheral
vascular diseases and erectile dysfunctions in men. Much of this is preventable
with treatment. Yet half of the people starting treatment for hypertension
quit within a year. Most do not last 90 days. Why? Medication side effects.
Wendy reacted to one antihypertensive drug after another. Her side effects
were dose-related, usually occurring with the first doses, a sure sign
of excessive dosing. Wendy knew her hypertension posed a serious threat
because relatives had died prematurely from hypertension-related strokes.
Wendy was motivated, but side effects made treatment impossible. "I
don't know what I'm going to do," she told me.
Experts acknowledge the problem: "Often, the cure is perceived
as being worse than the disease, and when this is the case, the patient
is unlikely to remain [in] treatment" (Elliott et al. 2000). People
get worn down by side effects such as dizziness, weakness, drowsiness,
fatigue, diarrhea, muscle cramps, and sexual impairments, and they give
up. Doctors often dismiss so-called "minor" side effects, but
minor reactions drive millions from needed treatment--with dire consequences.
There's a better solution.
Lower Doses Recommended by Experts
Because most side effects with antihypertensive drugs are dose-related,
experts recommend starting with the very lowest effective doses. But what
are they? Most doctors turn to the PDR, but the PDR's doses often aren't
the lowest. An analysis published in the Archives of Internal Medicine
in 2001 found that for 23 of 40 top-selling antihypertensive drugs, the
initial doses recommended by the drug companies in the PDR were much higher
than recommended by the Joint National Committee--the national board of
medical experts on hypertension (Cohen 2001).
For example, the manufacturer's initial dose for Norvasc, the fifth-most-prescribed
drug in the U.S. in 2001, is 5 mg. The experts recommend 2.5 mg, 50% less
medication. The manufacturer of Capoten (captopril) recommends 50 mg to
75 mg/day initially, 100% to 600% more than the 12.5 mg to 25 mg recommended
by experts.
When Tenormin (atenolol) was introduced in 1976, the one-size-fits-all
dose was 100 mg. It wasn't until 1980 that a 50-mg dose was available
and until 1989 that 25 mg was produced. The manufacturer still recommends
50 mg initially, 100% higher than the 25 mg recommended by the national
board.
The manufacturer of Lasix (furosemide), a commonly prescribed diuretic,
recommends 80 mg initially; the national board, 40 mg. The top-selling
diuretic hydrochlorothiazide (HCTZ) was recommended at 100 mg initially,
but this dose caused serious metabolic problems that affected millions.
Yet it took decades for manufacturers to lower the dose to 25 mg, still
100% higher than the 12.5 mg experts recommend today.
Similar over-dosing is seen with top-sellers Zestril, Prinivil, Altace,
Inderal (propanolol), Cardura, Cozaar, and many others (Table 4). Is it
any wonder why so many people quit treatment?
Some savvy doctors recognize that starting with the lowest dose not only
reduces risks, but allows people time to improve their diets, lose weight,
start exercising, and learn stress reduction or meditation. These methods
not only lower blood pressure, but can reduce the amount of medication
you need. As one specialist put it, "With blood pressure, it's easy
to overshoot the mark. That's why I always start low and give people time
to make other changes. Very often, their blood vessels relax over a period
of time and you wind up ultimately needing less medication. When I start
with standard doses, we spend the rest of our lives combating side effects."
Note: When
it comes to antihypertensive drugs, some patients are not taking them
frequently enough to maintain continuous blood pressure control. Many
antihypertensives are sold in "one-per-day" dosing units, but
some people need to take these drugs in two divided doses to achieve all-day
blood pressure control. Optimal control of hypertension requires blood
pressure checks throughout the day. This is the only way to make sure
the antihypertensive drug is not wearing off and endangering the arterial
system.)

ANTI-INFLAMMATORY DRUGS
In package inserts and PDR descriptions of nonsteroidal anti-inflammatory
drugs (NSAIDs) such as Motrin, Voltaren, Celebrex and Vioxx, the FDA specifically
requires drug companies to tell doctors to use "the lowest dose for
each patient." Why? Because gastrointestinal hemorrhaging and kidney
damage from NSAIDs have caused more than 16,000 deaths and 100,000 hospitalizations
annually. In 1999, the New England Journal of Medicine reported
that NSAIDs were the 15th leading cause of death in the U.S.: "Yet
these toxic effects remain largely a `silent epidemic,' with many physicians
and most patients unaware of the magnitude of the problem" (Wolfe
et al. 1999). And they are unaware that these reactions can occur without
any warning signs.
These and other NSAIDs side effects are dose-related, yet doctors and
patients often aren't informed about the very lowest effective doses,
so overdosing is common.
Motrin and Voltaren
When Motrin (ibuprofen) was introduced in America in 1974, the lowest
dose was 300 mg and the most prescribed dose was (and still is) 400 mg.
Yet, studies had already proven that 200 mg was effective for osteoarthritis
(degenerative arthritis) and rheumatoid arthritis (Chalmers 1969; Brooks
et al. 1970; Thompson et al. 1970; Hingorani 1970). Yet, low-dose Motrin
wasn't available for 10 years until over-the-counter Motrin arrived in
1984. Most doctors still don't know about its effectiveness and instead
usually prescribe 400 mg when half as much will do.
The standard dosage of Voltaren (diclofenac) for osteoarthritis is 50
mg twice or three times daily. Yet, studies before Voltaren's approval
showed that 25 mg three times daily is enough for many patients (Durrigl
et al. 1975; Mutru et al. 1978; Ciccolunghi et al. 1978, 1979).
Celebrex and Bextra
Dosing with new drugs like Celebrex and Bextra is even worse. Both drugs
are one-size-fits-all for osteoarthritis, their most common use. This
means that an identical amount is prescribed to football players with
injury-induced arthritis and to osteoarthritic 90-year-olds weighing 95
pounds and taking nine other drugs.
The standard dose of Celebrex for osteoarthritis is 100 mg, twice daily.
A Mayo Clinic study showed that 50 mg twice daily works for many people
with severe osteoarthritis. Moreover, compared with higher doses, the
50-mg dose not only caused fewer side effects, but wasn't associated with
kidney problems (Bensen et al. 1999). Starting at this lower, safer dose
would make sense, but the package insert and PDR don't say a word about
it, and the smallest Celebrex pill is a 100-mg capsule. Bextra was effective
at half (5 mg) and quarter (2.5 mg) doses in early studies, but this was
ignored and only 10 mg is offered for osteoarthritis.
OTHER DRUGS
A half dose of the antihistamine Allegra is effective, but because the
drug is one-size-fits-all and the pill is a capsule, a half dose is difficult
to get. Half doses of Claritin, especially Claritin-D, work for some people,
but for others even full-dose Claritin isn't enough. In fact, the FDA
wanted Claritin produced at 20 mg, but this dose could cause sedation,
which would hamper advertising. So doctors and patients are stuck with
a one-size-fits-all 10 mg dose that is inadequate for as many as 50% of
patients (Hall 2001).
Half doses of Zantac, Axid and Pepcid were proven effective long before
they were first marketed in the 1980s. It was only a decade later, when
the drugs were marketed over-the-counter, that lower doses became available.
Until then, people with mild heartburn got the same strong doses as people
with bleeding ulcers.
Prilosec is effective at a half dose of 10 mg, but there's scant information
about it in the PDR, so doctors rarely prescribe it. Over-the-counter
10-mg Prilosec will finally allow people to take a lower, safer dose for
mild conditions.
Viagra has been linked with more than 500 deaths and 1,500 heart attacks,
strokes, and other vascular events (Azarbal et al. 2000). The manufacturer
and FDA blame this on patients' age, health, or sexual activity, but many
deaths have occurred in men with no major medical problems and before
they even had sex. Suspicion remains that Viagra may affect blood pressure
or cause a cardiac arrhythmia in rare individuals. The standard starting
dose is 50 mg for all men ages 18 to 65, but starting with a half dose
is suggested, especially in middle-age men (Cohen 2000), the group in
which many reactions have occurred. A half dose works for some men; if
it isn't enough, it can be easily increased.
Lotronex generated a controversy that did not have to happen. Lotronex
is effective for irritable bowel syndrome, a nasty disorder that limits
people's lives, but the condition isn't an emergency requiring immediate
powerful dosing. Yet Lotronex was released one-size-fits-all, and after
causing hospitalizations and deaths, was withdrawn. As reported to the
FDA, one-size-fits-all drugs tie doctors' hands by keeping them from matching
doses to patients' needs or reducing doses when side effects emerge. Belatedly,
after unnecessary harm and a public furor, Lotronex was re-released in
2002--at a half dose.
Dosage is key with the widely used heart drug digoxin because excessive
doses can cause cardiac arrhythmias. For years, the recommended starting
dose was 0.25 mg. However, a half dose works. A 1997 study showed that
0.125 mg of digoxin improved congestive heart failure, whereas higher
doses produced diminishing improvement and greater toxicity (Slatton et
al. 1997).
Sleep medicines such as Ambien and Halcion (triazolam) are often effective
at half doses. Halcion is another drug released at excessive doses that,
after undue harm, widespread controversy, and being banned in many countries,
had its dose lowered.
The neuroleptic Risperdal was marketed in 1993 at 2 mg/day, which was
rapidly increased to 6 mg within three days. Doctors quickly learned--from
patients' adverse reactions--that these doses were excessive, and the
manufacturer now recommends 1 mg the first day, increasing to 3 mg in
three days. That's 50% less medication. Still, doctors start some patients
at 0.25 mg or 0.5 mg. Similar patterns have occurred with Haldol and other
drugs.
Because Xenical, a weight-loss drug, works by blocking fat absorption,
it can cause embarrassing side effects. Dosage is key, yet whether you
are slightly overweight or massively obese, whether you eat a little or
a lot, you get the same dose of one-size-fits-all Xenical: 120 mg three
times a day. A half dose was proven effective in studies, but the manufacturer
does not market it.
Zyban, widely advertised for smoking cessation, is started at 150 mg,
then doubled to 300 mg in three days, but even at this strong dose long-term
cessation rates aren't impressive. Some people taking Zyban can tolerate
only 150 mg, and others tolerate even less. In 2001, British regulators
issued warnings about seizures with Zyban at the standard dosage (Reuters
Health 2002). To obtain lower doses, some doctors prescribe Wellbutrin,
an antidepressant that's identical to Zyban but comes in lower doses.
In 2001, users of inhaled steroids for asthma or allergies learned that
these drugs had been discovered to cause bone loss. "The message
really is, we need to use inhaled corticosteroids at the lowest doses
that we can," Dr. Elliott Israel told the San Diego Union-Tribune
(Associated Press 2001). But why weren't they doing so from the start?
The list goes on and on (Table 5). Repeated discoveries of dose-related
toxicities years after people have started medications is not satisfactory.
We know that most side effects are dose-related, which means that many
are preventable by defining the lowest, safest doses initially, not years
or decades later after problems inevitably emerge or drugs go over-the-counter.

Doses for 36 Other Frequently Prescribed Drugs That You Won't Find

| Even if a drug isn't listed
here, a lower dose may still work. Many drugs are never tested at
lower doses or the research isn't published, but a lower initial dose
may be appropriate in some situations. Work with your doctor. Do not
change doses without medical direction; undertreatment can be harmful.

EXCEPTIONS
There are some drugs for which the low-dose approach does not apply.
For example, antibiotics, antifungal, and anticancer drugs should be used
at full doses. These drugs are not targeting you, but invaders that can
be made stronger if inadequate doses are used.
The Elderly
"The overall incidence of adverse drugs reactions in the elderly
is two to three times that found in young adults," states the New
England Journal of Medicine (Montamat et al. 1989). Although people
over age 60 comprise 19% of the population, they account for 39% of all
hospitalizations and 51% of all deaths related to medication reactions
(Smucker et al. 1990).
Seniors metabolize drugs more slowly than younger people, so they are
frequently more sensitive to their effects. That's why gerontologists
recommend extra caution in treating seniors and starting with low doses
(Table 6). Yet, for scores of top-selling drugs, drug company guidelines
tell doctors to use the same strong doses for young and old. Even when
we know that blood levels of drugs rise much higher in seniors, doctors
are told to ignore this fact and prescribe the same doses.
| Table 6: Lower Medication
Doses for Older People |
| Experts consistently recommend
lower doses for seniors. |
| J. Am. Geriatrics Soc. (Rochon et al. 1999)
|
"Choosing the correct dose of a drug
therapy is Geriatrics critical when prescribing for older people because
adverse effects are often dose-related. The conventional wisdom has
been to start low and go slow." |
| Goth's Medical Pharmacology (Clark et al.
1992) |
"In general the best approach is
to start with lower doses and to increase dosage slowly and in small
increments." |
| Public Citizen's Worst Pills, Best Pills
II (Wolfe et al. 1993) |
"If drug therapy is indicated, in
most cases it is safer to start with the dose which is lower than
the usual adult dose." |
| Drug Safety (Brawn et al. 1990) |
"Starting doses can often be reduced
in the elderly." |
| FDA Consumer Magazine (Williams 1997) |
"There is evidence that older adults
tend to be more sensitive to drugs than younger adults, due to their
generally slower metabolisms and organ functions. . . The old adage,
`Start low and go slow,' applies especially to the elderly."
|
| Archives of Internal Medicine (Everitt
et al. 1986) |
"The elderly are especially sensitive
to both the intended pharmacologic effects of drugs and their undesirable
adverse reactions." |
| BMJ (British Medical Journal) (Rochon et
al. 1997) |
"If drug treatment is necessary,
the lowest feasible dose of the drug should be used." |
| United States Pharmacopeia, Drug Information
(USP DI 1994) |
"Some clinicians recommend that geriatric
patients, especially those 70 years of age or older, be given one-half
of the usual adult dose initially." |
| Australian Family Physician (Gibian 1992)
Article title, |
"Rational drug therapy in the elderly,
or, How not to poison your elderly patients." Recommends: "The
starting dose should be lower than that recommended for younger adults;
the maximum tolerated dose may well be lower than for younger individuals."
"Select the minimum dose of the safest medication. . . . Start
low and go slow." |
For example, Allegra blood levels rise 99% higher in seniors versus younger
adults. Claritin rises 50% higher. Blood levels of top-selling antihypertensives
Zestril and Prinivil rise 100% higher. Blood levels of Prilosec and Nexium
are higher in the elderly. Yet, the recommended doses of all these drugs
are the same for young and old (Physicians' Desk Reference 2003).
The Celebrex package insert tells us "the incidence of adverse
experiences tended to be higher in elderly patients," yet no dosage
adjustment is recommended. Blood levels of Lipitor, Zocor and Mevacor
rise higher in seniors (Cheng et al. 1992). In fact, the Lipitor package
insert tells of "a greater degree of LDL-lowering at any dose in
the elderly patient population compared to younger adults" (Physicians'
Desk Reference 2003). So seniors should need less Lipitor, but they are
dosed the same as younger people. Could this be why so many reports of
cognitive and memory problems in older people taking statins are being
reported?
The FDA itself states, "There is evidence that older adults tend
to be more sensitive to drugs than younger adults, due to their generally
slower metabolisms and organ functions. The old adage, `Start low and
go slow,' applies especially to the elderly" (Williams 1997). Yet
the FDA keeps approving drugs at identical doses for young and old. Perhaps
this explains why 9% of all hospital admissions for seniors are related
to side effects from standard doses of prescription drugs (Montamat et
al. 1989).
Women
In the summer of 2002, two studies caused alarm by revealing increased
risks of cancer and heart disease with Premarin and Prempro, the top-selling
hormone replacement therapies (HRT) for menopausal women (Writing Group
2002; Lacey et al. 2002). The dose of estrogens in these drugs: 0.625
mg. But we've known for years that lower doses of Premarin (0.3 mg) and
other estrogens are often effective and cause fewer risks (Ettinger 1999;
Weinstein 1987; Greendale et al. 1998; McNagny et al. 1999). Might these
doses be safe enough today? Quite possibly, but the studies ignored this
obvious question, leaving women in the lurch.

The studies also didn't mention that from 1964 through 1999, the recommended
dose of Premarin for hot flashes was 1.25 mg. How much cancer did this
double dose cause? Why was such a strong dose approved in the first place?
These questions weren't answered. A similar pattern was seen with birth
control pills. The hormone doses in the first pills were 300% to 1000%
higher than in today's pills (Snider 2002; Marks 1999; Vessey et al. 1973;
Bottiger et al. 1980), yet it took decades--and hundreds of women's lives--before
high-dose pills were withdrawn and replaced with today's lower doses.
Similar problems are seen with other medications. A study of ibuprofen
for menstrual pain showed that 44% of women did just fine with the 200
mg over-the-counter dose, but the researchers still recommended 400 mg
for all women (Shapiro et al. 1981). Studies of cholesterol-lowering drugs
show that many women respond to lower doses (Wierzbicki et al. 2000; Ose
et al. 1999; Peters et al. 1994; Leitersdorf 1994), but they are routinely
prescribed the same doses as men.
Side effects with antihypertensive drugs occur more often in women (Lewis
1996; Israili et al. 1992), which, according to the American Journal of
the Medical Sciences, "could be due to the fact that women are treated
with antihypertensives using the dosage and schedule established with
men, even though it is well known that body size, fat distribution and
coronary artery size differ in women and men" (Lewis 1996).
Not all women require lower doses, but many do, especially small women.
Why aren't doses developed for them? A 2001 report of the U.S. General
Accounting Office found not only that women are underrepresented in the
dose studies, but even when dose differences are identified, they usually
aren't reflected in the final dosage guidelines (GAO 2001). A 2001 report
by the National Academy of Sciences recommended additional attention to
differences between men and women in diseases and treatments (Wizemann
et al. 2001). The panel's report added that medical researchers often
view men as the norm while underreporting rather than highlighting sex
differences. Commenting on this report, Dr. Woosley added that many drug
studies he sees "don't consider sex differences at all" (Kritz
2001).
Is this important? In the United States, 55% of women versus 37% of
men take a prescription drug daily (Bowman 2001). And of the 11 drugs
withdrawn in recent years, eight (maybe nine) affected women more than
men (Table 8).
ENTRENCHED PROBLEMS
WITH THE MEDICAL-PHARMACEUTICAL COMPLEX
"It's long been known that for individual subjects the dosage listed
on a drug label is not necessarily the right one," Dr. Carl Peck,
the highly respected director of Georgetown's Center of Drug Development
Science and a former division director at the FDA, stated in September
2002 (Zuger 2002). This is a chilling, and accurate, comment. Yet, the
medical-pharmaceutical complex--drug companies, FDA, and mainstream doctors--maintain
that our medications are as safe as possible. Clearly, this isn't the
case.
Compare the situation to the automobile industry in 1960, when auto
executives insisted that our cars were as safe as possible. Then we learned
that safety could be greatly enhanced with seat belts, air bags, bumpers
that didn't fall off, side panels that didn't cave in, dashboards not
made of metal, gas tanks positioned more safely, and other improvements.
Similarly, there's much that can be done to increase drug safety and end
the side-effect epidemic now, and it begins with identifying and marketing
the lowest, safest doses of all drugs.
Problems in Drug Industry Research
Why isn't this done now? Why aren't drug doses designed to fit individuals
and to prevent side effects? Don't drug manufacturers care? They do care.
"More and more senior executives are concerned that so many patients
are dropping out of therapy prematurely," declared DTC [Direct to
Consumer] In Perspective magazine in 2002. "So many are asking, `What
can I do to increase patient retention?'" (Smith 2002). Each year,
patients driven from treatment by side effects cost the drug industry
billions in sales.

Yet, many economic factors keep the system from changing (Table 9). Drug
companies are profit-driven entities, so marketing issues weigh very heavily.
Manufacturers feel great pressure to keep costs down while hastening new
drugs to market. And drug companies aren't held responsible for the huge
costs of dose-related side effects to the healthcare system. The result
is that marketing issues frequently outweigh medical science in drug company
decisions.
Indeed, marketing influences affect science so severely that even the
medical journals, which depend on drug company advertising, rebelled against
them. In September 2001, Reuters Health reported: "Seeking to curb
the growing influence exerted by drug firms over research findings, the
world's top medical journals announced steps on how to prevent firms that
fund studies from manipulating results to favor their drugs and bury studies
that are unfavorable" (Reuters Health 2001). The editors of JAMA,
Lancet, the New England Journal of Medicine, and ten others declared:
"We are concerned that the current environment in which some clinical
research is [conducted] may threaten medical objectivity. . .The use of
clinical trials primarily for marketing makes a mockery of clinical investigation.
. . ." (Davidoff et al. 2001). The journals implemented new guidelines
to ensure the integrity of clinical studies, but a year later few medical
schools had adopted them (Schulman et al. 2002).
Drug marketing is geared toward doctors' preferences, and doctors like
drugs that can be dosed simply and quickly. No time is required to match
doses to individual patients if drugs are one-size-fits-all. Expediency
sells. So does pumped-up effectiveness. Strong doses produce higher efficacy
numbers, which are essential for introducing a new drug into a competitive
market. Dr. Thomas Bodenheimer of the University of California, San Francisco,
reported: "Drug company studies are often done in younger, healthier
populations--providing better rates of effectiveness and fewer adverse
reactions--than those who will actually receive the drug" (Bodenheimer
2000).
Dr. Alexander Herxheimer, Professor Emeritus at the Cochrane Center
in Britain, concurred in Lancet. "For quick market penetration, a
drug must be simple to use and effective in the greatest number of people.
Drugs are often introduced at a dose that will be effective in around
90% of the target population, because this helps market penetration. The
25% of patients who are most sensitive to the drug get much more than
they need" (Herxheimer 1991). With nearly 100 million Americans taking
a prescription drug daily, that's 25 million people.
| Table 9: Why Don't Drug Companies
Produce Doses That Fit Individuals? |
| 1. Cost: |
Good dose studies cost a little more. |
| 2. Time: |
Good dose studies take a little more time,
placing a company at a disadvantage versus its less diligent competitors. |
| 3. Unrepresentative: |
Women and seniors are often underrepresented
in dose studies. A Populations: 2001 GAO analysis found that 78% of
subjects in dose trials are male. |
| 4. Study designs: |
Drug companies prefer to study serious
disorders because they are more stable and measurable. Serious disorders
usually require potent doses. When marketed, these same doses are
often prescribed for milder disorders that don't usually require such
potent doses. |
| 5. Less inventory: |
Fewer doses cost less to manufacture. |
| 6. Effective advertising: |
Higher doses produce higher efficacy rates,
which makes great advertising that influences doctors. |
| 7. Effective marketing: |
Simplicity sells. Doctors like one-size-fits-all
drugs because they are easy and quick to use. |
| 8. Weak FDA regulations: |
FDA definitions of "effective and
safe" do not ensure that the lowest, safest doses are marketed.
|
| 9. FDA analysis: |
Fearing long delays if a drug is denied,
drug companies use strong doses to ensure that the efficacy passes
FDA analysis. |
| 10. No public pressure: |
The public isn't aware of the side effect
epidemic or that most side effects are dose-related, so it doesn't
demand change. |
| 11. No accountability: |
The drug industry isn't required to pay
the billions for the extra doctors' visits, prescriptions, ER visits,
and hospitalizations from dose-related side effects. |
| 12. Basic economics: |
With record profits and weak regulation,
the drug industry has little incentive to change. |
The FDA's Role
As of November 2002, there were many scientists at the FDA concerned about
these dose issues, but also some who weren't. Overall, the FDA has not
pushed the drug industry to provide better dose studies or a range of
doses to match patients' differences.
The FDA's decisions about drug doses have been criticized even from
within the FDA itself. Based on his recent study showing that dozens of
drugs ultimately require dosage reductions years after approval, FDA officer
James Cross stated in September 2002, "We've seen a lot of situations
where drugs are approved by the FDA and subsequent important information
about their optimal dose is not determined until afterward" (Zuger
2002).
Even if the FDA wanted to push the matter, could it? The pharmaceutical
industry has the biggest lobby in Washington and is a top contributor
to elected officials. With Congress pressuring the FDA to approve drugs
faster and faster over the past decade, and the new commissioner vowing
to speed approvals even more, the FDA isn't likely to reject drugs for
better dose studies. "Making sure the dosages that are used best
serve the patients should be near the top of the agenda for regulators
and the prescribing community," Dr. Herxheimer insists. "Right
now this item seems to be nowhere on the agenda" (Herxheimer 2001).
Consequences of a Flawed System
The failure of the system is revealed by disaster after disaster. "Discovery
of new dangers of drugs after marketing is common," a 1998 study
in JAMA declared. "Overall, 51% of approved drugs have serious
adverse effects not detected prior to approval" (Moore et al. 1998).
Another study disclosed that 20% of all new drugs ultimately require
a new "black box" warning, indicating serious or fatal reactions.
The study noted: "Serious adverse drug reactions commonly emerge
after FDA approval. The safety of new agents cannot be known with certainty
until a drug has been on the market for many years" (Lasser et al.
2002).
How can long-term side effects be minimized? By using the lowest, safest
doses. For example, the jury is still out on the long-term safety of statin
drugs, but already serious nerve injuries are being reported. A 2002 study
found that "people who had taken statins were 4 to 14 times more
likely" to develop peripheral nerve injuries (tingling, numbness,
shooting or electrical pain, muscle weakness) (Gaist et al. 2002). These
reactions occur in one in 2,000 users of statin drugs per year. With 35
million Americans projected to take statins, that's 17,500 cases of peripheral
neuropathies each year. Discontinuation doesn't always bring reversal.
Most important, the risk is cumulative: the higher the dose, the greater
the risk.
Doctors and the Drug Industry
Some doctors are terrific. Some aren't. But even good doctors often don't
have all of the information you'd like in order to make good dose decisions.
Doctors ultimately decide which drugs are successful, so doctors are in
a position to demand better drug information, a wider range of drug doses
to fit patients and better information about nondrug alternatives. Doctors
can play a pivotal role, but so far they haven't demanded anything. Many
doctors aren't even aware that a problem exists.
"There is an informational void about pharmaceuticals in the training
of most doctors, despite the importance of the prescription in medical
care," stated Harvard physician Jerry Avorn. "Most of those
who have looked thoughtfully at this process have been appalled at its
inadequacy" (Avorn 1995).
The result is that doctors' knowledge of medications is less than ideal,
which is directly linked to the high rate of side effects. "Much
of the morbidity and mortality currently associated with drug therapy
is due to well-recognized adverse effects and reflects our inability as
health professionals to implement current knowledge fully," Dr. Alastair
Wood, Vice Chancellor of Medical Affairs at Vanderbilt, wrote in 1998
(Wood et al. 1998).
Experience shows that specialists are usually more knowledgeable about
drugs than general physicians, but many specialists don't even understand
the importance of precision prescribing. One heart specialist said, "Most
doctors don't think about dose-response. They think you either get side
effects or you don't." Dr. Herxheimer agrees: "Clinicians rarely
think critically about the dose-response relations of the drugs they use"
(Herxheimer 2001).
Marlene had a serious reaction to Lipitor, so her doctor switched her
to Zocor. When another reaction occurred, he switched her to Pravachol.
After another reaction, she quit treatment. "If a medication doesn't
work or causes side effects," a pharmacist said years ago, "most
physicians just switch from one to another, then another, then another,
until they either find a drug that works, or they or the patient give
up. Very few physicians go to the trouble of adjusting drug dosages to
fit their patients. Most don't deviate from the drug companies' recommendations."
Marlene was 64 and obviously sensitive to statin drugs, but the doctor
never considered simply reducing the dose. Why? Dr. Woosley, who develops
medical training programs, said "Only about fifteen of the medical
schools today teach formal courses in clinical pharmacology, which is
the discipline that emphasizes individual variability in response to drugs.
This small effort will never counter the overwhelming message from the
drug industry that one dosage is all that is needed and everyone will
respond nicely without side effects."
The result is that most doctors accept drug company information uncritically.
They assume that the drug companies and the FDA have chosen doses carefully
and that the recommended doses are right for everyone. They accept incomplete
side-effect lists in the PDR as the final word, even when published studies
repeatedly say otherwise.
Most doctors get their drug information from the drug company-written
PDR, the 80,000 drug representatives dispatched to doctors' offices, the
drug advertising that fills medical journals, drug company-designed studies,
and drug company-underwritten conferences. Many doctors don't hesitate
to accept $500 stipends and fancy dinners to receive drug company-paid
presentations.
One concerned doctor wrote to the New England Journal of Medicine:
"The conflicts are obvious to everyone in the field. Who hasn't sat
through a company-sponsored presentation by a well-known colleague without
squirming a little at the obvious bias in the discussion?" (Young
2000). A doctor visiting from Germany, appalled at the overt willingness
of doctors to accept drug company goodies, wrote to JAMA, "In the
long run this behavior will undermine the respect and trust of physicians
and the standing of the entire medical profession" (Vollmann 2000).
Dr. Marcia Angell, former Editor-in-Chief of the New England Journal
of Medicine, chided doctors, "It is well to remember that the
costs of the industry-sponsored trips, meals, gifts, conferences, symposiums
and honorariums, consulting fees, and research grants are simply added
to the prices of drugs and devices" (Angell 2000). But many doctors
eagerly accept these freebies. As one doctor wrote, "Physicians as
a group have an amazing capacity to rationalize their own greed."
Some doctors are rightfully concerned, but not nearly enough. "Many
physicians have grown accustomed to industry-subsidized education and
now resist paying even modest amounts to attend classes" offered
by unbiased medical centers, the Wall Street Journal reported
in 2002 (Hensley 2002). Yet, if you bring your own ideas about drugs and
doses to your doctor, don't expect a warm reception. Many doctors get
defensive, even hostile, when patients question their methods. If there's
any area that defines doctors, it's their ability to prescribe drugs.
They are the experts, and too often they choose to defend their turf rather
than expand their minds.
"Doctors don't like to be challenged," a pharmacist wrote.
"One doctor was prescribing Paxil well above the highest recommended
dosage. When I asked him about it, he said, `Are you a doctor? Who are
you to be telling me what to do!' Indeed, some doctors have difficulty
admitting even common side effects listed in the PDR. Being defensive
doesn't strengthen doctor-patient relationships. More and more, doctors
are perceived as pill pushers and as defenders of the medical-pharmaceutical
machine instead of their own patients.
This perception is enhanced when drug companies can so easily convince
doctors to prescribe new drugs even when older, better-known drugs are
equally effective. For years, the FDA has warned doctors against using
new drugs unless a patient has a specific need. Dr. Janet Woodcock, Director
of the FDA Center for Drug Evaluation and Research, has stated, "The
sad truth is that, even after all the clinical development that occurs
with every drug and even after drugs have been approved for a time, we
only have a crude idea of what they do in people" (Cimons 1999).
With the FDA approving drugs faster than ever, the American public is
frequently the world's first population to try out new drugs.
Yet doctors repeatedly make new drugs bestsellers within months. Drug
reps fill doctors' cabinets with "free" samples, knowing that
if patients do well on them, they won't want to switch. Drug advertising
seizes upon any difference, no matter how trivial, to sway doctors to
prescribe expensive new drugs with no track records, and doctors readily
oblige. You'd think that after recent disasters with Baycol, Rezulin,
Lotronex, Duract, Redux and Fen-Phen, doctors would learn, but they keep
prescribing new drugs like Clarinex, Nexium, and Bextra at greater risk
and cost. These repeated problems compelled Drs. Marcia Angell and Arnold
Relman, another former editor of the New England Journal of Medicine,
to warn, "Few Americans appreciate the full scope and consequences
of the pharmaceutical industry's hold on our health care system"
(Angell et al. 2001).
One healthcare observer wrote, "The root cause is the physician,
his lack of knowledge or intellectual curiosity. The pharmaceutical companies
are trying to make a buck any way they can, and it is up to the physician
to have the fortitude to resist." He has a point. Doctors can't have
it both ways. They can't be objective advisors to patients while being
so reliant on drug company data and accepting of drug company influences.
Such reliance explains why people today make more visits to alternative
practitioners than to mainstream doctors. It explains why mainstream doctors
remain largely unaware of proven-effective alternatives like omega-3 oils
for reducing inflammation and sudden cardiac death, policosanol and inositol
hexanicotinate for reducing cholesterol, or the importance of coenzyme
Q10 for people taking statins. It explains why mainstream doctors continued
to make Premarin, with its conjugated horse estrogens, a top-seller for
decades although many types of human estrogens (estradiol, estriol) were
available.
It explains why, despite hundreds of studies in medical journals, most
doctors don't know anything about magnesium's essential role for normal
blood vessel functioning, or that 80% of westerners are deficient in magnesium.
By balancing calcium, magnesium is a safer, natural, much less expensive
way to help reduce blood pressure than the prescription calcium blockers
for which doctors write $4 billion in prescriptions each year, yet few
mainstream doctors know about it.
Without drug-company backing, vital information about lower drug doses
and nondrug alternatives can take years or decades to permeate mainstream
medicine. That's why Over Dose: The Case Against The Drug Companies
was written to expose the problems in the medical-pharmaceutical complex,
while providing low-dose and other important self-help information to
patients and doctors. That's why, despite its revelations about the drug
industry and mainstream medicine, the Journal of the American Medical
Association, Publishers Weekly, Booklist, Mensa
Bulletin, and everyone else have strongly recommended the book (see
reviews at www.amazon.com).
To begin bridging the information gap in mainstream medicine, a free
electronic newsletter and a series of inexpensive booklets with evidence-based
information for patients and their doctors are being made available. You
can sign up for the newsletter or obtain the first booklets (Magnesium
for High Blood Pressure and Magnesium for Migraine Headaches) at www.MedAlternatives.com.
If we are to improve our medical care and end the side effect epidemic,
we have to make all doctors integrative practitioners. To do so, we have
to develop new mechanisms for getting good drug and nondrug information
to mainstream doctors.
What You Can Do
If you are doing well on a medication, that's good. That's the goal: receiving
benefit without side effects. But if medications are causing problems,
or if the next time you need a medication you want to minimize the risk,
you need to inform yourself about the lowest, safest doses. Do not reduce
doses without your doctor's guidance. Undertreatment can have serious
medical consequences.
Hopefully, you have a doctor who recognizes the importance of precision
prescribing. Some do. Following a 1999 article in Newsweek (Cohen
1999), one doctor wrote, "I have always found that patients do well
on low, 'subtherapeutic' doses, which are not just placebos." Another
wrote, "As a physician who is a patient with a chronic illness, I
can tell you from my vast experience that the doses in the PDR are often
way off."
If your doctor, like most doctors, isn't aware of the low-dose alternatives,
what can you do? Inform yourself. The day when you could rely on doctors
to provide all of the important drug information is long gone. Doctors
have less time than ever to read medical journals or to search the medical
literature. You can access it yourself at www.PubMed.org, established
by the National Institutes of Health. People spend a lot of time researching
an auto or stereo purchase; they need to do the same for their own bodies.
YOU HAVE A RIGHT TO
BE INFORMED
The American Medical Association's Code of Medical Ethics states: "The
patient's right of self-decision can be effectively exercised only if
the patient possesses enough information to enable an intelligent choice"
(American Medical Association 1999).
What is "enough information?" Surely, if a lower dose is effective,
you have a right to know about it. If you are prescribed a standard dose
of a drug without being told about an effective lower dose, you haven't
received informed consent. If the standard dose has done major harm, you
may have grounds to sue.
Higher doses are certainly appropriate sometimes. Emergencies and acute
situations demand immediate relief. However, 90% of office visits aren't
for acute problems, but for minor or chronic conditions. There's time
to match doses to individuals. There's time to start with a lower, safer
dose and then to adjust upward, if necessary. You are paying the bill
and taking the risk, so you have a right to be fully informed about the
options.
The low-dose method is especially fitting for:
- Older people
- Small people
- People with multiple medical conditions
- People taking multiple medications
- People with histories of medication sensitivities
- People wanting to minimize costs
- People wanting to minimize risks
The "start low, go slow" approach may take a little more time
initially, but it saves a lot of time (and money) in the long run. Some
people will get surprisingly good results with a low dose and never need
higher doses. Some won't, and the dose will need to be increased. Even
then, they are assured that they are getting exactly what their bodies
need.
Not everyone opts for the low-dose approach. Some people know that they
aren't sensitive to medications. With such people, starting with standard
doses is valid. Indeed, some people seem resistant to drugs and require
very high doses. The key is to match the dose with the person. Ultimately
it doesn't matter whether you need a low dose or a high dose--what matters
is that you get the right dose for you.
Doing so requires good dose information and a range of drug doses. If
anything, the drug industry is providing less of each. The irony is that
other industries not only recognize the differences among people, they
capitalize on it. They produce cars, clothes, cosmetics, and all kinds
of commodities in vast arrays to match individual sizes and needs. But
with its monopolistic patents and sway over doctors, the drug industry
can do what it likes and charge what it wants.
In 2001, 3.2 billion prescriptions were filled in America--12 prescriptions
for each man, woman, and child. Forty-six percent of adult Americans take
a prescription drug every day. Each year, drug sales increase 25% (Pharmacy
Times 2002), and medication side effects remain a top killer. How can
we restore sanity to this system? It will have to begin with you.
You are paying the bill and taking the risk, so you have a right to
ask questions and to request better information. You have a right to ask
your doctor why he's selecting a specific drug at a specific dose. Are
there lower doses that work? What is his source of information? We must
require doctors to explain their decisions, to think about their choices,
and to consider other sources of information.
Most people don't like taking medication. If they must take it, they
want to use as little as possible. When the low-dose approach has been
offered to patients, most have opted for it, side effects have dropped
dramatically, success rates have climbed, patients are pleased, and so
is the doctor. Most side effects are avoidable. The side effect epidemic
can be halted, and everybody wins. But the current system is entrenched,
so change is going to have to begin with us.
