Panacur C (fenbendazole) is a broad spectrum parasiticide used to treat hookworms, roundworms, tapeworms, and whipworms in dogs. It is also used by veterinarians to treat other parasites.
For: Dogs (6 weeks of age or older)
Benefits:
•
Can be added to food
•
FDA-approved for use in dogs
•
Side effects are rare
How it works:
Fenbendazole is a member of the benzimidizole group of anti-parasite medications which makes it a relatively broad-spectrum medication. It binds to parasitic proteins which leads to damaging the integrity and the transport function of cells in parasites.
Cautions:
Side effects are rare, but may include loose stools. Since humans can contract roundworms, hookworms, and tapeworms from pets, it's important to maintain good personal hygiene. It's also important to eliminate fleas and to not feed your pet uncooked meat or fish. To prevent re-infection, clean up stools on a daily basis.

Panacur C saved Blue's life. She was very very sick when I took her to the vet. She had whipworms. We had never heard of them before, but believe me, they are no match for Panacur C. Now Blue is back in the "pink"! Thank you 1-800-PetMeds
My vet had recommended Panacur at an exorbitant price. I called PetMeds and got the same medication $40 less than what my vet was going to charge me. Thanks, PetMeds!
I took my dog in to the vet and he thought she had Addison Disease. She was VERY sick. Well finally after $900 of vet bills I took her to another and turns out she just had roundworms really bad which we have 4 dogs and she was the only one that had them. This is the greatest wormer ever! It really saved my Bae Bae!
I have had this product perscribed by my vet and I recently found out it was over the counter and web. My dogs had parasites instead of worms and this is the only product that works on everything. Quick too. 3 days and done. Not 3 weeks like other products
We ordered this and gave it to our puppy as directed and it worked perfectly! we haven't seen any more worms and he seems healthy and happy and energetic! Thanks!
Yesterday I noticed that my 6 week old boxer puppy,Lincoln, had worms in his stool. His stool was normal other than the worms... So I went and got panacur 1gram packets. (i use this worker with my 2lb Chihuahua since she was a puppy) well I gave Lincoln his first dose yesterday and by last night he had diarrhea. And still has it this morning. I really don't recall this happening with my Chihuahua but all dogs are different I suppose. Anyways is this normal?
Interceptor is used to prevent heartworm disease and intestinal parasites. If your pet does have an intestinal parasite infection, Panacur C can be used. Yes.
As a routine wormer Panacur C is dosed daily for 3 days. However, there are some instances, for example to treat giardia, that the medication is given daily for 5 days.
You can ask your veterinarian why he gave you the 4 Gram packets. For the future, as long as your pet weighs between 21 and 30 lbs, you would give your pet 3 grams (a 1 gram packet PLUS a 2 gram packet) daily for 3 days. If your pet's weight goes above 30 lbs, then you would use a 4 gram packet daily for 3 days.
