How does Safe-Guard Equine Dewormer Paste work?

Each gram of Safe-Guard Equine Paste Dewormer contains 100 mg of fenbendazole. The antiparasitic action of Safe-Guard Equine Paste Dewormer is believed to be due to the inhibition of energy metabolism in the parasite.

Cautions:

Side effects associated with Safe-Guard Equine Paste Dewormer could not be established in well-controlled safety studies in horses with single doses as high as 454 mg/lb (1,000 mg/kg) and 15 consecutive daily doses of 22.7 mg/lb (50 mg/kg). Particularly with higher doses, the lethal action of fenbendazole may cause the release of antigens by the dying parasites. This phenomenon may result in either a local or systemic hypersensitive reaction. As with any drug, these reactions should be treated symptomatically. Safe-Guard Equine Paste Dewormer has been evaluated for safety in pregnant mares during all stages of gestation and in stallions with doses as high as 11.4 mg/lb (25 mg/kg). No adverse effects on reproductivity were detected. The recommended dose for control of 4th stage larvae of Strongylus vulgaris, 4.6 mg/lb (10 mg/kg) daily for 5 consecutive days, has not been evaluated for safety in stallions or pregnant mares.
