A single fast acting dose of Capstar (nitenpyram) should kill the adult fleas on your pet. If your pet gets re-infested 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.
We recommend you follow up CAPSTAR treatment with a monthly flea control product such as PROGRAM, Frontline or Advantage. Then keep CAPSTAR on hand for the times when there is a visible flea re-infestation.

Great product for flea control by Sue Dog08/07/2012
After brief wet spell my pack, 6 Bull Terriers, 1 Peronese, were scratching constantly. Used Capstar and don't notice any scratching after 10 days. My dogs are sensitive to Adams shampoo so I avoid topical treatments.
Capstar kills fleas fast! by 5dogmom from Seattle area11/09/2012
Capstar kills fleas fast, stopping your dogs scratching and discomfort, while you work to rid your house of fleas (I use Fleago). It was a godsend in the 2012 "flea season."
