The OD MD: Physician and Author Jay Cohen Says
Pharmaceutical Companies Are Endangering Lives by Recommending Drug Doses
That Are Too High for Many Patients
By Fred Dickey
Los Angeles Times Sunday Magazine, February 15, 2004
Jay Cohen believes he knows what went wrong in
Michael Hope's life. Hope, 56, sits in his home in the San Gabriel Valley
and tries to use his brain, an effort of tortuous frustration for a former
quick-thinking business executive. Not only does he suffer from constant
muscle pain throughout his body, but also from the anguish of short-term
memory loss and the inability to command words in simple conversation.
When he finally gives up on the word he is trying to think of and attempts
a substitute, he has forgotten not only what he has been trying to say,
but what the entire conversation was about.
The reason for his Job-like travails? Not a dread
disease or an exotic virus from Africa. After years of tests and consultations
with doctors, chemists and others, Hope believes he suffers from overdoses
of the drug Lipitor, the top-selling prescription drug in America today
and a member of the family of drugs called statins that are hailed as
lifesavers for reducing cholesterol. Hope took the drug for four years.
The dosage was just 10 milligrams per day, the standard dose recommended
by the pharmaceutical company. So what's the problem?
The standard dose is the problem, says Cohen,
an activist physician and author who has picked a fight with the powerful
pharmaceutical industry. Lipitor should have been available in doses of
5 milligrams or even 2.5 milligrams, Cohen says, but he doesn't believe
the problem is confined to Lipitor. It also is true for many prescription
medicines today, Cohen argues in "Over Dose,"
his 2001 book that points fingers at people in the medical profession.
Standard doses are damaging lives and are linked to the deaths of thousands
of Americans each year, he says. Precise numbers aren't known, but Cohen
cites a 1998 article in the Journal of the American Medical Assn. that
said prescription drugs cause more than 2.2 million severe medical reactions
in hospitals and could kill more than 100,000 people a year.
"We have a huge problem with side effects,
year after year, decade after decade," Cohen says. "Every family
is affected by it. I don't know how many people have told me that their
parents didn't die of disease; they died of drugs. The problem is solvable
if we just pay attention to it."
Jay Cohen is slight and bookish, a 58-year-old
father who looks like an accountant [I guess I need a trainer: I played
all of the sports plus rugby and boxed as a kid and have been exercising
for 30 years -- JSC], not an agitator. His fashionable rustic home blends
into a Del Mar hillside and rests on some of the most expensive dirt in
California. Prominent among the large light-filled rooms is a study that
is book-deep and organized, pointing to a systematic fellow who might
develop a rash if his glasses weren't where he left them.
The uncommon breadth of the man is apparent as
he proudly shows off his garden, with its splashes of color that would
flatter a Costa Rica travel brochure. When he endured his own severe medical
afflictions that effectively ended his medical practice in the 1990s,
he turned horticulture into therapy and taught himself about tropical
plants.
To Cohen, pharmacology is like collecting baseball
cards: He does it for fun. However, his dedication is the glitter-eyed
intensity of a door-to-door evangelist.
It all started with Prozac. When the drug was introduced in the U.S. in
1988, it held the promise of a new era of depression management at a starting
dose of 20 milligrams. Cohen and many other physicians started using it
as a welcome tool to help angst-ridden patients, prescribing it in the
recommended strength. But then, several of Cohen's patients started crawling
the walls.
The loud-bang imprint on Cohen's mind was from
a female patient in her early 30s who suffered from mild chronic depression.
"I gave her the recommended dose," he says. "In three days
she was psychotic, totally psychotic. But when I stopped the drug, she
recovered in a few days." So Cohen lowered her dose, eventually to
5 milligrams, and she did fine. He also lowered dosages for other patients,
in some cases by having them dissolve the pill in liquid and drink it
over three or four days. It worked, and they got better.
Seeking to understand the experience, Cohen found
data that showed Prozac to be effective in much lower doses even before
it was released at 20 milligrams. "I found research that shocked
me. I thought, 'Wait a minute! If you don't give me the information to
do my job right, how can I protect my patients?' I took that very personally."
Life soon got even more personal when, in 1990,
he was attacked by a rare vascular disease known as erythromelalgia, and
also an autoimmune connective-tissue disease. He spent years immobilized
by grinding pain that accompanied every movement. It was impossible for
him to walk without tendons from hip to shoulder pleading to stop. In
his treatment, he discovered just how personal drug therapy could get.
"I tried scores of medications for these illnesses and had many instances
where the standard doses were much too strong." So he relied on the
lessons learned from Prozac"to start low, go slow."
Since he could no longer practice medicine, he
applied himself to correcting the harm he had observed. He learned to
use software that allowed him to voice-activate his computer, and he spent
the next decade turning out reams of published material on patient-oriented
subjects, including his own disease, on which he became one of the world's
few experts. He also has published articles on alternative treatments,
especially on the use of magnesium. His research is not the test-tube
variety, but mainly consists of delving into dusty, often-ignored medical
studies and patient experiences, which when taken together can turn the
arcane into the obvious.
Maybe because his illnesses reminded him that
the human body is always running downhill, Cohen became purpose-driven;
one of the lucky who had found the job he was born to do: "I was
fortunate as a child, and I don't say this arrogantly, to be a mathematics
prodigy. So this came easy to me, and I found it challenging. I always
had a natural interest in pharmacology and seriously considered specializing
in it, but I was afraid I'd end up working for a drug company in New Jersey
and having to wear a tie every day."
Even though Cohen's health is improving, he has
no intention of returning to medical practice as we think of it. "Doing
this is where I'm needed," he says of his current work. Recently
he formed a nonprofit corporation called the Center
for the Prevention of Medication Side Effects through which he will
continue to track drugs whose recommended doses he believes are too high.
Over the years, in addition to writing his book,
Cohen has lectured at medical schools and health-care conferences, and
he has written ceaselessly on the dangers and misuse of prescription drugs.
Yet he has drawn little heat from the establishment, in part because the
Journal of the American Medical Assn. and other respected publications
have favorably reviewed his work.
In the Nov. 6, 2002, issue of JAMA, a reviewer
said, "Jay Cohen, MD, long a thorn in the industry's side, has written
a highly readable, user-friendly, and well-researched account of a serious
clinical issue plaguing the everyday practice of medicine. The problem
is over-medication."
Robert Ehrlich is head of DTC Perspectives Inc.,
a New Jersey pharmaceutical publishing company. He formerly was vice president
of consumer marketing for Parke-Davis, the company that developed Lipitor.
He says pharmaceuticals limit dosages to the ones that fit the needs of
most patients. "Otherwise, a multiplicity of choices would be confusing
for patients and too time-consuming for doctors."
Has Cohen overstated his case? "If the problem
is serious side effects, probably. I think his basic premise is fair.
I think he's right that they should offer lower doses; I don't think he's
right that there's a big risk to society in the doses they do offer."
A potential risk of Cohen's theory, he says, is that if doses are too
small to be effective, then patients might stop taking medications.
Jim Dickinson, publisher of "Dickinson's
FDA Webview," a watchdog publication in Camp Hill, Pa., known for
being evenhanded, has watched Cohen's work closely. "I think everybody
agrees he's right. It's obvious to everybody that the ax he's got to grind
is not for anything but a noble cause."
The "cause" Dickinson refers to is eliminating
a practice followed in the drug-approval process whereby companies submit
drugs at higher dosages than they need to be. "When they do that,
they're playing Russian roulette with the patient," Dickinson says.
By opposing those practices, he explains, Cohen "has had a very beneficial
effect. I commend him."
The process starts to go wrong, Cohen says, the
moment the idea of a new drug is developed by a pharmaceutical company.
To gain FDA approval, the company must demonstrate that the drug works
against whatever ailment it targets. They do not have to show that it
is better than existing similar drugs, but only that it is more effective
than a placebo, which is another name for a fake pill. Consequently, Cohen
says, it behooves the company to put its new drug through clinical trials
at a strong enough dosage so as to take no chances that the FDA will find
it insufficiently effective. And since the FDA can only approve dose levels
that the company submits, the frequent result is that a recommended dosage
of, say, 10 milligrams is put on the market rather than maybe 5 milligrams,
which might better serve many people who can't tolerant the higher amount.
Dr. Karen Lasser of Cambridge Hospital and Harvard
Medical School says that in the pre-market trials, drug companies usually
recruit younger, healthier people for their studies. "The patient
who ultimately takes the drug may be elderly and on 10 other medications,
but those patients tend to be excluded from the trials," thus the
dosage being tested may be far too strong for eventual users.
Even if the drug company later goes back to the
FDA and seeks authorization for a lower level, the original dosage already
may have sunk in with physicians. Pharmacologist Joe Graedon, author of
"The People's Pharmacy," agrees that it is not unusual for drug
companies to select a high dose based on early research. "It's a
fast way to get [FDA] approval. The name of the game is to get your drug
on the market as soon as possible, even though it may not be the proper
strength for a diverse population. Sometimes they will come back later
and apply for other doses. However, physicians get in the habit of prescribing
the original dose."
The whole drug-marketing game, Cohen says, is
to make sure that a new drug can be shown to outperform competitive drugs
already available, and the way to get results fast is to make the dosage
strong, as in, "Gee, doctor, I've only been on the drug three days
and already I feel a difference. Thanks."
He says that pharmaceutical companies will research
a drug in variable doses, and when they find the one they consider most
marketable, they drop all other findings. Then they publish the preferred
result in medical journals, hand it to doctors and advertise it widely.
"When you're designing your own studies,
you can prove almost anything you want," Cohen says. "Companies
have learned that if you want a doctor to switch from, say, Motrin to
Bextra, you've got to be able to give a reason it works better, it's stronger,
it helps more people. They've got to find an edge, so you use a stronger
dose, you get a better result, but you also get side effects, but they
don't worry about that." That's why you see so many ads on TV for
new drugs, he says. The companies want you, the patient, to go into your
doctor's office and ask about it, thus greatly increasing the chances
of having it prescribed.
And if the dose is strong enough, the bang will
be quick and dramatic, even though trouble may arise down the line. Patients
love those quick results, and doctors know it, Cohen says. Rather than
patiently inch the dosage up to just what the patient needs, the doctor
who already relies on drug companies for guidance will prescribe a higher
dosage that will bring surefire results, but sometimes much more in the
form of side effects, some mild, some serious. Of a very common side effect,
Cohen says, "If it's someone else's diarrhea, it's no big deal, but
if it's yours, it's a big deal."
Cohen also believes that drug companies exert
far too much influence on the drugs doctors choose for treatment. He says
physicians must bear part of that blame simply because they often lack
basic knowledge of pharmacology and instead fall back on what drug company
salespeople advise: "The standard medical school requirement is for
one course in pharmacology in the second year, before the student has
seen even one patient. That's it! One course. When a physician enters
practice, he is at the mercy of drug companies." Most doctors, he
says, get about 95% of their information from drug companies' sales reps,
seminars, advertising and samples. Even the book they use, the "Physician's
Desk Reference," is written by the drug companies.
Others agree. Lasser says, "The reason many
doctors go to pharmaceutical companies for drug information is that it's
easier: The drug reps are there, they're smiling, they're paying for lunch
and handing out free samples."
The free samples are a particular problem,
Cohen says. "Why are doctors given samples to hand out?" Cohen
asks. "When you're trying to get your drug positioned in the market,
how do you do that? You advertise the hell out of it. You get doctors
who will speak positively about it. You give them stipends for going to
seminars in nice places with golf courses. And then there are those free
samples. It's a freebie, and when the doctor gives it to a patient, the
patient says, 'Gee, thanks.' "
As an example, Cohen compares Nexium, the new
stomach-acid controller, to Prilosec, which is virtually identical and
for which a generic is available for a price about 10 times less. But
once a patient tries Nexium and is doing well, he's not going to want
to switch, Cohen says. "Every dollar that goes into these 'me-too'
drugs that are virtually the same as existing drugs is a dollar that is
bled out of the health-care system. Drug companies are looking for their
profits and will squeeze it every way they can."
Cohen is talking to the Democratic Club of Solana
Beach, an affluent suburb of Del Mar. The audience of 20 or so are Birkenstock-shod
McGovern types who kept the faith. Cohen has been talking for more than
an hour, and aging bladders notwithstanding, the audience hangs on every
word. This guy is smart, a believer, articulate in a professorial way,
and he's talking about something even more important than Bush's tax cut:
their health and the drugs that repose, even as he speaks, in pillboxes
in each of their bathrooms. His points are as known to him as his name,
and he glides through them:
* About 75% to 85% of all side effects are dose-related,
which means the drug might be fine, but the dose might be wrong for you.
Doses must be individualized, which means that in most cases, the doctor
should start you on the lowest dosage and gradually increase it to its
desirable level. "Doctors are giving the same dose of a powerful
anti-inflammatory to Shaquille O'Neal for his arthritic toe as to Ally
McBeal for her tennis elbow, and that's insane. Vets or farmers will tell
you that they adjust doses for the size of animals, so why don't we do
it for people?"
* One danger of overdosing
is that many patients will simply stop taking drugs because of unacceptable
side effects. How many people have died of heart attacks because they
couldn't tolerate the medications that might have kept them alive?
* Twenty percent
of drugs on the market underwent dosage changes after their introduction.
Eighty percent of those were reductions.
* Ultimately, drugs
are a business. Doctors and scientists don't call the final shots, marketers
do.
* When severe side
effects occur, most doctors just switch medications. Instead, why don't
they try reducing dosages?
In a later conversation, Cohen is asked to name the drug groups he believes
are most frequently prescribed at excessive doses. He begins with the
caveat that they are all good drugs when used properly, but then ticks
off four:
* The statins, particularly
Lipitor, Zocor and Crestor; the standard starting doses are too strong
for the millions of users with mild-to-moderate elevated cholesterol.
* Antidepressants,
particularly in the same family as Prozac, Zoloft, Paxil, Celexa and Effexor.
These drugs are notorious for causing many side effects such as agitation,
insomnia, weight gain and sexual dysfunctions. These are all dose-related.
* Anti-inflammatories,
especially Celebrex and Bextra. Celebrex is the top seller and Bextra
is the newest fast-selling one. Both are very strong. Both are one-size-fits-all
for their primary use, osteoarthritis. Celebrex is recommended by the
manufacturer at 200 milligrams, and Bextra at 10 milligrams. The data
show, however, that half doses of each are highly effective. Anti-inflammatory
drugs cause more injury and death than any other group of drugs. Every
medical authority urges the use of the lowest effective doses of these
drugs, but with Celebrex and Bextra, the lowest, safest effective doses
aren't available.
* Premarin
and Prempro, which are hormones for menopause. Recent studies have linked
these drugs to cancer, causing havoc for menopausal women. The untold
story is that the estrogen dose that was studied, 0.625 milligrams, was
actually half of the recommended dose, 1.25 milligrams, that was urged
on women from 1964 through 1999. How much harm did the higher dose cause?
No one knows.
Although Cohen realizes how daunting it is for
a patient to confront a doctor, he believes patients must become more
assertive about drug treatment. And, increasingly, they have more resources
to do so as solid information written for the laity proliferates on the
Internet and elsewhere.
"First, patients must tell their doctors
if they've had past problems with side effects, and then insist they would
rather start with the lowest effective dose of a drug," Cohen says.
"Doctors hear a lot of dumb questions, but they're also trained to
respond to the informed patient who insists on being the guardian of his
or her own health."
