Product Overview
Fenbendazole is a benzimidazole carbamate anthelmintic developed for veterinary use. It belongs to the same class as albendazole and mebendazole and shares their mechanism of action: binding to parasite tubulin, inhibiting microtubule polymerization, and disrupting energy metabolism by blocking glucose uptake. This leads to parasite death and expulsion from the host animal.
Fenbendazole exhibits broad-spectrum activity against gastrointestinal nematodes (roundworms), lungworms, and cestodes (tapeworms) affecting cattle, sheep, goats, swine, poultry, and companion animals. It is effective against both adult and larval stages of many parasites, including Haemonchus, Ostertagia, Trichostrongylus, Cooperia, Nematodirus, Bunostomum, Ascaris, and Dictyocaulus species. Fenbendazole is well-tolerated across a wide safety margin in target species and has been a cornerstone of veterinary parasite control programs for decades.
