What is Fenbendazole (Panacur®)?

Fenbendazole is an anthelmintic medication used to treat internal parasites in dogs, including roundworms, hookworms, whipworms and some tapeworms. It belongs to the benzimidazole class of drugs, which disrupt the metabolic processes of parasites, leading to their elimination.

How Fenbendazole Works in Dogs

Fenbendazole works by disrupting the energy metabolism of parasites. It binds to the beta-tubulin in the parasite’s cells, inhibiting the formation of microtubules necessary for glucose uptake. Without glucose, parasites lose energy and eventually die. This mechanism is effective against a wide range of intestinal worms, ensuring your dog’s digestive system stays healthy and parasite-free.
