Fenbendazole, also known as Panacur and Safe-Guard, is a broad spectrum benzimidazole anthelmintic used to treat and/or prevent intestinal parasites in dogs, cats, ferrets, horses, goats, rabbits and fish. It is used for the control of a variety of parasites in the gastrointestinal tract including roundworms, hookworms, whipworms and the taenia species of tapeworms. It is also effective against lungworms in pigs and, when administered after deworming, it can help prevent the recurrence of giardia in puppies.
It works by securing a binding with beta-tubulin in the parasite, disrupting their energy formation and causing cell death. As with most medications, fenbendazole can have side effects, but they are typically mild and short-lived. For more information, consult your veterinarian.
In a recent study in calf herds, fenbendazole was found to be comparable with the more commonly used anthelmintic ivermectin in the treatment of nematodes in calves. However, it is important to note that the study was done on a single farm and that additional research is needed.
Safe-Guard (fenbendazole powder) is FDA-approved for the treatment of internal parasites in puppies, kittens and adult dogs up to 88 pounds. It is safe to use in combination with most other wormers. Follow your veterinarian’s deworming schedule for your specific species of pet. It is important to deworm at the correct intervals to ensure proper growth and development, and to maintain your pet’s good health. Your vet may recommend fecal tests to determine the type of parasites that are in your pet’s gut.
