Fenbendazole is a broad-spectrum anthelmintic medication commonly used to treat a wide range of parasitic infections in animals, particularly dogs, cats, horses, and livestock. It works by interfering with the energy metabolism of parasites, effectively killing them and eliminating them from the host’s body. Fenbendazole tablets are especially effective against gastrointestinal parasites such as roundworms, hookworms, whipworms, and certain types of tapeworms. The medication targets the parasites’ ability to absorb glucose, thereby starving them of energy and causing their eventual death.
