Product Description

HEARTGARD® (ivermectin) is a monthly heartworm chewable given to your cat that prevents heartworm infection and helps treat and control hookworms. An infected mosquito that bites your cat can lead to potentially deadly heartworm disease in less than three months. That’s why it’s important to keep your cat on a monthly heartworm preventive year-round. Check with your veterinarian to make sure your cat has a current heartworm test result on file. Given monthly, HEARTGARD prevents heartworms from developing inside your cat and keeps them safe from future infections. Plus, it comes in a tasty, beef-flavored chewable tablet that makes it convenient to treat even the most finicky felines. All cats are at risk for heartworm disease, no matter where they live. Talk to your veterinarian about preventing heartworms in your cat with HEARTGARD. Check out our Heartworm Disease Chart for more information on what medicine is best for your cat.

Helpful Tips:

If you miss a dose, administer it as soon as you remember. If it is already time for the next dose, skip the missed dose and resume the administration schedule. Never administer two doses at once. If you forget to treat your pet for 8 weeks in a row, you should administer as soon as you remember, but your pet should be re-tested for heartworms within the next 6 months because infection could have taken place when the pet was untreated.

Remove only one chewable at a time from the foilbacked blister card. Return the card with the remaining chewables to its box to protect the product from light. HEARTGARD for Cats can be offered to the cat by hand or may be added to a small amount of cat food. If manual dosing is required, the chewable should be broken into pieces for administration. Food should be routinely available during the day of treatment administration. If cats are fasted, or if the chewable is not broken into pieces for manual dosing, then reduced absorption may result. A relationship between reduced absorption and reduced efficacy has not been established. Care should be taken to see that the cat consumes the complete dose. Treated animals should be observed for a few minutes after administration to ensure that part of the dose is not lost or rejected. If it is suspected that any of the dose has been lost, redosing with a new chewable is recommended. Fragments of chewables have occasionally been observed in the feces of some cats; efficacy of the product was not adversely affected. HEARTGARD for Cats should be given at monthly intervals when mosquitoes potentially carrying infective heartworm larvae are active. The initial dose must be given within a month (30 days) after the cat’s first exposure to mosquitoes. The final dose must be given within a month (30 days) after the cat’s last exposure to mosquitoes. For optimal performance, HEARTGARD for Cats must be given once a month on or about the same date. If treatment is delayed, whether by a few days or many, immediate treatment with HEARTGARD for Cats and resumption of the recommended dosing regimen will minimize the opportunity for development of adult heartworm. It is recommended that cats should be tested for existing heartworm infection prior to starting treatment with HEARTGARD for Cats. Cats already infected with adult heartworms can be given HEARTGARD for Cats monthly to prevent further infections. Monthly treatment with HEARTGARD for Cats also provides effective removal and control of adult and immature hookworms (A. tubaeforme and A. braziliense).
