The fleas on your pet are in the adult stage. An adult female flea, living on a pet, can lay up to 2,000 eggs in her lifetime. With CAPSTAR® (nitenpyram), almost all adult fleas will be gone within 4 hours for dogs and 6 hours for cats.
How CAPSTAR Works:
CAPSTAR starts working in just 30 minutes. A single dose of CAPSTAR should kill the adult fleas on your pet. If your pet gets reinfested with fleas, you can safely give another dose as often as once per day.
CAPSTAR is safe for puppies and kittens 4 weeks and older, weighing 2 pounds or greater, as well as for pregnant or nursing dogs and cats.
How to Use:
A single dose of CAPSTAR kills the adult fleas on your pet. If your pet gets reinfested with fleas, you can safely give another dose as often as once per day. To administer CAPSTAR tablets, place the pill directly in your pet's mouth, or hide it in food. If you choose to hide the tablet 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 administer a second pill.
