An unapproved clenbuterol product associated with two horse deaths in Louisiana has prompted the Food and Drug Administration to remind veterinarians and horse owners that no generic versions of the drug are approved for use in animals.

The unapproved product is labeled Clenbuterol HCl, according to a statement issued Nov. 24 by the FDA Center for Veterinary Medicine. The agency has confirmed at least two deaths associated with the “super potent” product at Louisiana State University’s veterinary hospital, and an investigation is under way, added an FDA spokesperson.

Three ill horses recently treated at the veterinary hospital all tested positive for clenbuterol, but only one had very high levels of the drug in its system, said Dr. Rebecca S. McConnico, an assistant professor of veterinary medicine at the university. Two of the horses were euthanized, and one recovered, said Dr. McConnico, who has heard unconfirmed reports of three additional clenbuterol-related fatalities in Louisiana.
