The following warning was issued today by the FDA's Center for Veterinary Medicine in Rockville, Maryland:
The U.S. Food and Drug Administration is alerting veterinary medical professionals, as well as those who work with horses, that a synthetic progesterone product commonly used in these animals may cause reproductive system disorders and other adverse effects in people who become exposed to the drug. The FDA is providing this alert because of the nature of the adverse events, some of which have occurred in teenage girls.
