Fenbendazole Bolus

What is fenbendazole? Fenbendazole (brand names Panacur®, Safe-Guard®) is a medication used to treat a variety of parasites (e.g., roundworms, hookworms, lungworm, whipworm, and certain types of tapeworms) in dogs. Its use in cats for the treatment of parasites is 'off label' or 'extra label'.

Fenbendazole should be given with food to reduce gastrointestinal upset.

Give this medication as directed by your veterinarian. Fenbendazole is often given once daily for 3 consecutive days and then again in another round 2-3 weeks later.

It is important that your pet receives all of the doses recommended by your veterinarian for best results. Do not stop early or skip doses unless recommended by your veterinarian. Retreatment may be necessary if doses are missed, the medication is stopped too soon, or if reinfection from the environment occurs.

This medication should take effect within 1 to 2 days, but visible effects will take the entire duration of treatment to be recognized.
