FDA Warns Horse Owners and Veterinarians about Deaths Due to Unapproved Clenbuterol

The FDA has become aware of the deaths of several horses in Louisiana associated with the use of a product labeled as Clenbuterol HCL. 
Horse owners and veterinarians should be alert, as there are no generic clenbuterol-containing products approved for animals.

One clenbuterol-containing product --Ventipulmin--is approved as safe and effective for use in horses.

The FDA asks persons aware of horse injuries or deaths that may be linked to the use of Clenbuterol HCL to contact the FDA
office in their area.  For a listing of FDA Consumer Complaint Coordinators:  http://www.fda.gov/opacom/backgrounders/complain.html
