Fenbendazole for Rabbits

Fenbendazole (also known as Panacur) is a dewormer that can be used with many animals. In rabbits, it is mostly used for the removal of parasites such as giardia and pinworms. It can also be administered to combat encephalitozoon cuniculi, another type of parasite that causes head tilt, hind-limb paralysis, cataracts and sometimes death.

  1. Safety

    • Fenbendazole should not be given to an animal that is allergic to it, though it is safe for most rabbits. There are no known drug or food interactions with this drug. Doctors Foster and Smith's website reports fenbendazole is a safe medication for your pet. Negative side effects and toxicities are not likely to occur.

    Signs of Allergy to Medication

    • Though side effects are rare, they do happen. The main effect that may be seen in your rabbit is vomiting. It is important to watch your pet for signs of allergies to the medication or of reaction to the dying parasites. If you see any of the following, you need to immediately notify your veterinarian. Allergic reactions may include facial swelling, scratching, hives, diarrhea, shock, cold limbs, seizure or coma.

    Dosing Your Rabbit

    • Your veterinarian will give you dosing instructions. Always follow these for maximum effectiveness of the medication. Fenbendazole for rabbits needs to be given for multiple consecutive days to be a successful intervention. If you miss dosing your pet, give it as soon as you remember. Don't give it if it is almost time for the next dose and never give two doses together. If you remember too late, skip the one you missed and go to your regular schedule. Let your vet know of the missed dose and ask for further instructions.

    Giving the Medication to a Rabbit

    • It is sometimes hard to give your rabbit medication. It may be a good idea to give fenbendazole with food. The medicine is a crystalline powder and can easily be mixed with food. Use a small amount of food when administering the drug. When the rabbit has eaten it all, she can then be given the remainder of her food. This ensures that the rabbit actually takes all the medication.

    Warnings

    • Do not diagnose and treat your rabbit yourself. Always consult with a veterinary professional before starting any medication. Fenbendazole is for parasites; some of these parasites are zoonotic (able to infect humans). Therefore, you should not only discuss how to treat your rabbit; you should work with your veterinarian on preventing possible human infection and reinfection of your pet.
