A New Breed of 'Diet' Pills
Drugs Approved for Diabetes,
Depression, Epilepsy Grow Popular For Their Weight-Loss Side Effects

(August 22, 2006) -- Like many people who struggle with their weight, Sally
Krawczyk has tried everything from liquid diets to low-carb regimens to
Weight Watchers. And like many dieters, each time she stopped, she gained
back all the pounds she'd lost.
But the 51-year-old teacher says she's finally discovered a successful
way to lose weight. On the advice of her doctor, she's been taking an
antiseizure medication and two
antidepressants -- and has lost 135 pounds in
18 months.
Ms. Krawczyk doesn't suffer from seizures or
depression, but she has
found the medication beneficial in another way. "The medicine helps control
my need to
constantly be eating," says Ms. Krawczyk, of Murrieta, Calif.,
who now weighs 220 pounds and hopes to lose 40 more. "Without it I could eat
and eat and never feel full or satisfied."
In the unending quest for a miracle diet pill, Americans are trying an
array of prescription drugs approved by the Food and Drug Administration to
treat a variety of illnesses. None of them have been approved as diet drugs
-- but for many, weight loss is a side effect.
The list includes drugs meant to treat attention-deficit hyperactivity
disorder (Adderall and
Ritalin), depression (Wellbutrin), epilepsy (Topamax
and Zonegran), diabetes (Glucophage and Byetta), sleep disorders (Provigil),
smoking (Zyban) and even opiate overdoses (Narcan). Often these drugs are
used alone, but sometimes they're taken in combination with each other or
with popular weight-loss medications, such as phentermine.
While there are no hard data on the trend, doctors and patients say it
has been increasing for several years and that the drugs are being used by
Americans -- especially women -- of all sizes, from obese people to
anorexics. Adderall, a stimulant that was originally marketed as a diet drug
in the 1970s under a different name, is said to be the weight-loss agent of
choice for everyone from soccer moms to Hollywood starlets, debutantes and
college kids, many of whom take it without a prescription.
"People are looking for a quick fix," says Christine Gerbstadt,
spokeswoman for the American Dietetic Association. "Taking a pill is so much
easier than going to the gym or cutting back on portions."
Though the drugs generally work to suppress appetite or food cravings,
many have additional, less desirable side effects, which can include
abdominal cramps, anxiety, insomnia and cognitive problems. One drug,
Wellbutrin, comes with a "black box" warning that it may cause increased
risk of suicide in children and adolescents.
Doctors are permitted to prescribe drugs for applications other than
those for which they are approved -- a use which is termed off-label. But
not everyone is getting these drugs from a physician. Some are buying the
drugs from Internet pharmacies or from Canada. A number admit they are
taking drugs prescribed for friends or family members.
When Jacqueline Colozzi, a 20-year-old college student in New York,
wanted to drop a few pounds, a friend with an Adderall prescription offered
her some. "It was easier just to take a pill as opposed to working out or
watching what I ate," says Ms. Colozzi, who weighs 110 pounds. After losing
10 pounds over the course of a year, she got tired of never wanting to eat
or sleep. "I realized it didn't make me feel good," she says.

The Internet, too, is giving the use of off-label drugs for dieting a
boost. Web sites such as FatNews.com often run articles on the latest
research being done on the weight-loss effects of these drugs. Users compare
the success rates and side effects of the medications in an increasingly
varied range of message boards, from Web sites dedicated to information
about drugs, such as Askapatient.com, to eBay.
Still, the practice of prescribing drugs off-label for weight loss is
controversial. To begin with, the drugs can be expensive, and insurance
companies typically don't pay for off-label uses of drugs. What's more,
doctors have varying opinions on the weight-loss effects of these drugs. In
general, they say, they may help people lose about 5% to 10% of their body
weight.
More important, these can be risky drugs, especially when taken without a
doctor's supervision. Although drug companies and independent researchers
have studied the weight-loss effects of many of these drugs, including
Wellbutrin and
Topamax, to date the FDA hasn't approved any of them for
weight loss.
"There's no evidence of the safety or the efficacy of going
off-label for weight loss," says George Blackburn, associate director of
Harvard Medical School's Division on Nutrition. When patients request
off-label drugs to help them lose weight, Dr. Blackburn suggests that they
modify their diet and exercise instead. If that doesn't work, he will
prescribe one of the approved weight-loss drugs to help them control their
cravings. "We see no need to go off label," he says. "We have zero tolerance
for the side effects."
