Eight thoroughbreds in Ocala, Fla., developed severe neurological trouble within 36 hours of treatment with compounded toltrazuril/pyrimethamine, used for treatment or prevention of equine protozoal myeloencephalitis EPM). One horse died during a seizure while another was euthanized after two days of treatment at the University of Florida.

DR. RAMEY NOTES: Compounded medications were responsible for the deaths of 21 polo horses in Florida a couple of years back. Compounding pharmacies make medications to give to horses, but there is lots of controversy regarding compounded products. In my opinion, it’s always better to use an FDA approved product when treating your horse – that way, you can be assured of product safety, quality, and effectiveness.
