Flubendazole is a broad-spectrum benzimidazole anthelmintic used widely in poultry in Europe. It is the fluoro- analogue of mebendazole and has similar properties. It is administered orally to chickens, turkeys, and game birds in the form of a paste, pellet, tablet, or premix for incorporation into the feed.
Flubendazole is effective against gastrointestinal roundworms (Ascaridia spp , Capillaria spp, Heterakis spp), and in higher doses, some tapeworms and Syngamus trachea (gapeworm).
Note: Do not give this drug parenterally to poultry, as subcutaneous administration causes intolerable pain, while intramuscular (IM) injections induce inflammation.
