Fenbendazole Tablet

Fenbendazole is used against susceptible parasites in animals, but the indication should always be matched to the species and exact product label.

• Dogs: FDA-labeled fenbendazole products treat and control roundworms, hookworms, whipworms and Taenia pisiformis tapeworms.

• Cattle, buffaloes, sheep and goats: Indian Panacur labeling covers gastrointestinal nematodes, lungworms and tapeworms.

• Horses: Indian Panacur labeling provides veterinary use against susceptible gastrointestinal parasites and specifies a horse dosing regimen.

• Other species or parasites may require a different fenbendazole product and veterinary direction.

Fenbendazole is a benzimidazole anthelmintic. It acts on parasite beta-tubulin and interferes with microtubule formation, disrupting essential cellular processes needed for parasite survival. This ultimately helps eliminate susceptible worms from the animal.

Its spectrum is not unlimited. A product labeled for one animal species or parasite cannot automatically be assumed appropriate for another. Parasite resistance can also affect treatment response, making veterinary diagnosis and appropriate parasite-control planning important.

There is no single universal fenbendazole tablet dose because the required amount depends on animal species, body weight, parasite and product concentration.

These are examples from specific veterinary labels, not an individualized prescription for this unspecified product. Do not substitute a different tablet strength or extend treatment without veterinary direction.

• Choosing fenbendazole correctly requires more than matching the ingredient name.

• Confirm the animal species and current body weight.

• Check the tablet's exact mg strength and approved indications.

• Verify that the target parasite appears on the product label.

• For food-producing animals, confirm the applicable meat and milk withdrawal period.

• Do not assume a dog, horse or livestock formulation can be used interchangeably.

• Follow the exact supplied label when it differs from another fenbendazole product.

• Veterinary fenbendazole products can have different storage, presentation and withdrawal requirements. For example, the current Indian Panacur leaflet says to store the product protected from light and lists withdrawal periods of 4 days for milk, 8 days for meat from cattle, buffaloes and horses, and 14 days for sheep and goats. These periods apply to that labeled product and should not automatically be transferred to another fenbendazole tablet.

  Monitor the animal for treatment response and unusual reactions. Persistent parasite signs may indicate reinfection, an incorrect diagnosis, inadequate treatment, or parasite resistance and should be assessed by a veterinarian.

Fenbendazole Tablet should be treated as a veterinary medicine unless the exact product has documented authorization for another use. Fenbendazole is not FDA-approved for humans, and there is insufficient evidence to establish it as a safe or effective human treatment. In particular, it should not be marketed or used as a human cancer treatment.

Veterinary products should be used only for the species and indications on their label or under appropriate veterinary direction. Do not extend treatment beyond the labeled duration without veterinary supervision. FDA has reported cases of bone-marrow hypoplasia and pancytopenia in dogs receiving fenbendazole for longer than the labeled 3-day duration.

Human self-administration also carries uncertain safety risks. Published medical literature has reported clinically significant liver injury following self-use of veterinary fenbendazole.

For food-producing animals, follow the exact meat and milk withdrawal periods on the supplied product label. Keep veterinary medicines away from children and do not use an animal product as a substitute for a human antiparasitic medicine.
