Roundworm Medication for Cats

Roundworms are internal parasites that can cause serious health problems in your cat or kitten. Both of the two species of roundworms--Toxocara cati and Toxascaris leonina--are treated with the same medications.

  1. Roundworm Infection

    • Your cat may have contracted roundworms from ingesting worm eggs off the ground, when it nursed from its mother or by consuming an animal that contained roundworms.

    Pyrantel Pamoate

    • Available in both a liquid and a paste form, pyrantel pamoate is one of the more popular cat wormers, usually found in brand names such as Drontal.

    Febantel

    • Available in pill form, incorporated in Drontal Plus, this medication can be given to cats and kittens over 6 weeks of age.

    Selamectin

    • Selamectin is found in Revolution, which is an FDA-approved topical medication that treats and controls roundworms and hookworms, and also prevents heartworms.

    Prescription Medications Versus Over The Counter Medications

    • Selamectin products are the only roundworm medications that require a prescription. All of the others can be purchased without a prescription from your local pet store or through an online merchant.
