What is Panacur C for Dogs?

Panacur C is a dewormer for dogs, containing fenbendazole in the form of granules. It is available without a prescription, but is only for use under veterinarian approval or recommendation. Panacur C works to rid hookworm, whipworm, roundworm, and non-dipylidium caninum tapeworm infections in dogs only. Panacur C should only be used in healthy dogs that are 6 weeks or older.  If your dog’s weight is in-between the suggested dosing sizes, it is safe to use the next higher size.

  • Q:

    I gave my dogs per vet 3 days of panacur for hook and whip worms. Can I now follow up with safeguard ? I can't afford the panacur.
    Asked on 10/3/2014 by Badger from Washington, United States

    1 answer

    • A:

      Badger,

      Fenbendazole 22.2% granules (Panacur C) is used as a 3 day, weight based (50mg/kg), therapy for the control of hook, whip, tape, and round worms in dogs and puppies. Safe-Guard Canine Dewormer is also an over the counter product containing fenbendazole approved for use as a dewormer in dogs. Varying strengths and dosage forms of this medication exist that may differ from the Panacur C that was suggested by the veterinarian. It is important to contact your pet’s veterinarian to address affordability and discuss over the counter alternatives before choosing the best medication for your pet. Your pet’s veterinarian will also help you to determine if follow up therapy is needed.

  • Q:

    My cat has Giardia. If panacurc can be used to treat this parasite, what is the recommended dose for a 7 lbs cat and how many doses and how often can it be repeated?
    Asked on 7/26/2014 by songbird from Michigan, United States

    1 answer

    • A:

      Fenbendazole, the active ingredient in Panacur C, is used for the treatment of Giardia. The Panacur C formulation is marketed for dogs with amounts of active ingredient that would likely be too high for a cat. There are different dosing ranges and durations of treatment that are used by veterinarians when treating with fenbendazole in cats. Consult with your veterinarian to determine if febendazole would be the preferred choice in treating your cats giardia.

  • Q:

    Is it common for small dogs (pom weighing 5 1/2 lbs) to experience some vomiting and diarrhea after first dose? Afraid to give her the second dose. Bloody mucus in stool continues.
    Asked on 7/22/2014 by mj1014 from Tennessee, United States

    1 answer

    • A:

      Panacur C is an antiparasitic agent used to rid dogs of various types of worms. This medication is usually tolerated fairly well, but vomiting and diarrhea may occur. Since this is the case with your pet, we suggest you contact your veterinarian so your dog may receive the best care.

  • Q:

    Is it still effective if I just dose for two days instead of three?  I'm trying to save money plus it's hard to dose my dog.  
    Asked on 7/2/2014 by Anna79 from Texas

    1 answer

    • A:

      The product is normally dosed for three consecutive days. The reasoning to give it for the third day is to ensure that the infection is gone, preventing further therapy.

  • Q:

    We gave our dogs the recommended dosage for 3 days. Do we need to do a follow up dosage, and if so when?
    Asked on 6/10/2014 by Barbarabj from Bonanza, OR

    1 answer

    • A:

      Panacur C is used to remove parasites in dogs and generally well tolerated at higher doses well beyond the recommended dose. Also, this medication generally does not cause any adverse effects at the recommended dose. Three consecutive days of treatment is typically recommended, but the duration of therapy may vary depending on the type and severity of parasite infection you are treating. We recommend contacting your dog's veterinarian to check if your dog still needs a follow-up drug regimen once the Panacur C treatment is completed.

  • Q:

    How often do i need to worm my dog with this medication?
    Asked on 4/1/2014 by mellie from south georgia

    1 answer

    • A:

      Mellie,

      This question depends on the type of dog you have, the dog's age, and the amount of exposure to worms/eggs. The manufacturer recommends the following schedule to be used as guidance: Newly weaned pups (6-8 weeks old) should be dewormed at 6, 8, 10, and 12 weeks after birth. Dogs older than 6 months old should be dewormed at least twice yearly. Please contact your pet's veterinarian for further guidance.

      Thank you,

  • Q:

    I want to make sure I am getting the right dose for my dogs their Giant Schnauzers one is 46 mo. the other is 6 mo. And the oldest one weights 95- to 100 lbs. the pup weights 45-50 lbs. So the oldest one should take 8 grams and the youngest one 5 grams
    Asked on 12/21/2013 by Donald from Toledo, OH, United States

    1 answer

    • A:

      Donald,

      The suggested dosing for the Panacur C is 1 gram per 10 pounds of body weight. If your pet is in between the suggested weights, it is safe to go with the higher dose - a 35 pound dog may be treated with the 40 pound dose. The dosing schedule by weight is listed below.

      10 pounds - 1 gram
      20 pounds - 2 gram
      30 pounds - 1 gram + 2 gram (3 grams total)
      40 pounds - 4 gram
      50 pounds - 1 gram + 4 gram (5 grams total)
      60 pounds - 2 gram + 4 gram (6 grams total)
      80 pounds - Two 4 gram (8 grams total)
      Over 80 pounds - Use combinations to obtain recommended daily dose

  • Q:

    Have you ever heard of giving panacur c for 6 days instead if the recommended 3 days?
    Asked on 9/28/2013 by Patty

    1 answer

    • A:

      Patty,

      The package information on the Panacur-C states that a 3-day course of medication is recommended for deworming, however, if your veterinarian has recommended a longer course of treatment, we recommended heeding their instructions.  The Panacur-C package does indicate that deworming schedules may vary depending on the climate where you live and the activity of your dog.  If you have questions about appropriate deworming, please contact your veterinarian, as they will be best able to guide you based on your dog and your locale.

      Thank you,

Comments about Merck Animal Health Panacur C (fenbendazole):

I bought this powder form of panacur after our vet prescribe it in the liquid form.
The amount necessary in the liquid form per treatment is a lot to handle with active dogs. The powder form mixes well with the dogs food and dissolves rapidly.
This is the second treatment with panacur and we are having positive results.

Comments about Merck Animal Health Panacur C (fenbendazole):

Once you understand the deworming procedure - give the dewormer over a three-day period then again in three weeks and again in three months, it's easy to switch to a home deworming. This is the exact same Panacur that comes from your vet, but this one is much cheaper. I combined two different dosage amounts for my dogs, and the amounts are easy to look up online. I'm so glad to have found this website.

Comments about Merck Animal Health Panacur C (fenbendazole):

I dose my dogs with Panacur every 6 months, more often when they are hunting in the field and coming into contact with many critters and their 'leavings'. It is safe, easy, and very effective. I have never had a negative reaction or any problem with this product, and the dogs remain worm free.

Comments about Merck Animal Health Panacur C (fenbendazole):

My dogs are so much happier now! Unfortunately, I missed cleaning up some of their messes from the backyard and will have to retreat them again soon. Don't make the mistake I made: Clean up ALL their little piles before and until you finish treatment to make sure you do not have to repeat it right away!
