Active Ingredients: Fenbendazole

Fenbendazole Boluses are an anthelmintic drug used to treat gastrointestinal and respiratory worm infections in camels, cows, goats, sheep, and horses. It is an effective treatment for parasites such as Bunostomum, Haemonchus, Nematodirus, Ostertagia, Strongyloides, and lungworms like Dictyocaulus viviparus.

Fenbendazole is classified as a benzimidazole carbamate. It shows a broad spectrum of activity against both mature and immature nematodes and cestodes. Fenbendazole works by inhibiting glucose uptake. This drains a parasite's glycogen reserves, which leads to its death.
