Diagnosis of Parasites: Specific diagnoses require laboratory testing. Consult your veterinarian for help in the diagnosis, treatment, and control of parasitism. Dogs can become infected with several different kinds of tapeworms. Panacur® C only kills Taenia species of tapeworms. If you continue to see tapeworm segments in your dog’s stool after treatment with Panacur® C, consult your veterinarian.

Recommended Deworming Schedule:

Deworming schedules may vary depending on the climate where you live and the activity of your dog. The following schedule should be used as general guidance. Newly weaned pups (6 to 8 weeks of age) should be dewormed at 6, 8, 10, and 12 weeks of age. Treat the dam at the same time as the puppies. Dogs over six months of age should be dewormed at least twice each year. Each deworming requires 3 daily treatments. (See Directions)


Store at controlled room temperature 68-77°F (20-25°C).
