Panacur Side Effects

Panacur is an anti-parasitic medicine used to remove worms such as roundworms, hookworms, whipworms and, to a lesser extent, tapeworms from the gastrointestinal tract of animals. Panacur is the trade name for the drug fenbendazole and is manufactured by Intervet-Scherring Plough. It can be given as powdered granules, oral liquid suspension or a paste to many types of animals, including dogs, cats and farm livestock.

  1. Common Side Effects

    • Panacur is usually safe and is difficult to overdose, but minor side effects sometimes occur. Vomiting is the most common side effect seen after administering Panacur. If the animal begins vomiting, call your veterinarian before resuming treatment.

    Secondary Diarrhea

    • You might witness diarrhea after giving Panacur to your pet. This typically arises from irritation in the gastrointestinal tract as the medicine attacks the worms. If the diarrhea becomes severe or is bloody, call your veterinarian at once.

    Less Common Reactions

    • Some less common side effects of Panacur include heavy breathing, itching, face swelling, and lethargy. These are signs of an allergic reaction. If any of these become prominent, call your veterinarian for advice, or take your animal in for a quick check-up.

    Serious Side Effects

    • Blood disorders such as anemia and low white blood cell counts can develop, although they are rare and restricted almost exclusively to birds. In laboratory tests, some rats also developed liver tumors.

    Drug Interactions

    • No known drug interactions exist with Panacur. However, always give a list of your pet's medications, vitamins and supplements to your vet to help him diagnose your pet's problem and prescribe the right course of treatment.
