Government
announces ban on ephedra
Tuesday, December 30, 2003 Posted: 12:34 PM EST
Ephedra is a stimulant that is used
as an ingredient in weight loss and appetite suppression pills and
over-the-counter nasal decongestants and asthma medications. According to a
study commissioned by the Food and Drug Administration (FDA), Ephedra may
seriously harm and kill some who use it.
Ephedra has been
used in products for:
Asthma, Common Cold, Weight
loss
Hay fever/Allergies, Congestion, Cough
Increased Energy, Weight
lifting formulas
Ephedra can produce the following
adverse reactions: heart attack, stroke, tachycardia, paranoid psychosis,
depression, convulsions, coma, fever, vomiting, palpitations, hypertension, and
respiratory depression. The research adds to the long-standing controversy about
the dietary supplement, which is also marketed as an energy booster and
treatment for respiratory illness.
"The use of dietary supplements
does pose a health risk to some people," says Neal Benowitz, MD, professor
of medicine and chief of clinical pharmacology at the University of California,
San Francisco. "Just because it's natural, doesn't mean it's safe."
Benowitz and postdoctoral researcher Christine Haller, MD, reviewed the 140
reports of deaths or injuries the FDA received related to ephedra. Researchers
concluded that ephedrine use "definitely" or "probably"
caused harm in 31% of the cases. Of these cases, three people died, seven
suffered permanent injury and four required ongoing medical treatment.
Ephedra, derived from an Asiatic
shrub, contains ephedrine, a stimulant that acts on the central nervous system
to relax bronchial tubes. A synthetic form of ephedrine is used in
bronchodilators and over-the-counter medications like Sudafed and Actifed, which
fall under the FDA's watch.
However, the FDA does not currently
regulate many products containing ephedra because it is labeled as a dietary
supplement and thus is protected under the Dietary Supplement Health &
Education Act of 1994. Pursuant to the Act, the FDA cannot regulate dietary
supplements such as ephedra unless it has been proven to be unsafe. Drug
companies have taken advantage of the current status of ephedrine and have
attempted to produce a "legal" amphetamine by mixing ephedrine with
other stimulants such as caffeine.
