Fenbendazole is a benzimidazole anthelmintic, that has broad-spectrum, and a wide safety margin. It binds to 3-tubulin astructural protein that blocks polymerization of tubulin into microtubules, which damages the integrity and the transport function of cells in parasites. The reason behind the wide safety margin is due to its infinity to the parasitic tubules rather than mammalian. It is considered safe for use in pregnancy in all species.

Fenbendazole is minimally absorbed after it is given orally, and is metabolized to the active compound oxfendazole sulfoxide and sulfone. It is excreted in the feces and urine.
