Fenbendazole is a broad-spectrum anthelmintic belonging to the benzimidazole class. Since its introduction in the 1970s, it has become a staple in veterinary medicine for controlling gastrointestinal nematodes, cestodes, and certain protozoa in livestock, companion animals, and exotic species.

Its chemical structure, featuring a phenylthio group at the 5-position of the benzimidazole ring, enhances its anthelmintic potency and spectrum compared to earlier benzimidazoles like thiabendazole. This modification also contributes to its favorable safety profile in target animals.
