Straight to the gut:
the fenbendazole difference

SAFE-GUARD is the only dewormer on the market using fenbendazole as its active ingredient. Fenbendazole is a unique molecule known for its broad-spectrum, fast-acting ability to kill parasites.

Unlike pour-ons and injectables, the oral administration of SAFE-GUARD takes it right to the gut to fight parasites where they live.

As a member of the benzimidazole class, SAFE-GUARD remains powerful while resistance grows against endectocides, like Ivermectin and Doramectin.
