Instructions
Giving Capstar Tablets to Your Pet
Ask your veterinarian for one or more Capstar tablets, or purchase them online.
Administer the tablet to your pet. Make sure that he has swallowed the pill and did not spit it out on the floor. You can give the pill to your pet by placing it directly in his mouth or by hiding the pill in a favorite food.
Rid your home of fleas and be sure to wash your pet's bedding in warm soapy water to ensure that all fleas and larvae have been destroyed. This will help prevent a reinfestation.
Repeat the process if the fleas reinfest your pet. Capstar is safe to give daily.
