CAPSTAR Tablets kill adult fleas and are indicated for the treatment of flea infestations on dogs 4 weeks of age and older and 25 pounds of body weight or greater. A single dose of CAPSTAR should kill the adultfleas on your pet. If your pet gets re-infested with fleas, you can safely give another dose as often as once per day. To give CAPSTAR Tablets, place the pill directly in your pets mouth or hide it in food. If you hide the pill in food, watch closely to make sure your pet swallows the pill. If you are not sure that your pet swallowed the pill, it is safe to give a second pill. Treat all infested pets in the household. Fleas can reproduce on untreated pets and allow infestations to persist.
