Mebendazole (Mebenvet, Vermox) is a common type of dewormer used to treat a number of parasitic worm infestations, including nematodes and some cestodes. It works by keeping the worm from absorbing sugar (glucose), so that the worm loses energy and dies. Mebendazole is the same drug given to humans for pinworm infections.
Typical Dosage: 50 mg/kg as a single oral dose. Eliminates roundworms and capillary worms. If given in feed, 60 ppm for 7 days for chickens, turkeys and guineafowl, and 120 ppm in feed for 14 days for geese, ducks, partridge, and pheasants.
