Capstar® (nitenpyram) is a fast-acting, oral flea treatment for dogs and cats that kills adult fleas before they can start an infestation.

No, Capstar is available online and at retail outlets without a prescription.
Capstar kills adult fleas. Its active ingredient, nitenpyram, starts killing fleas in just 30 minutes.
Capstar kills adult fleas before they can lay eggs. Additional treatments of Capstar may be required as existing flea larvae emerge into adult fleas.
Capstar can be used daily, as needed, to help treat and control an existing flea infestation. A monthly flea preventive is recommended for long-term flea prevention.
Capstar is available as an oral flea tablet. Place the pill directly in your pet's mouth or hide it in food. If you hide it 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.
A single dose of Capstar 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 a day.
If you are currently administering a monthly flea preventive such as Frontline Plus (fipronil) or Advantage II (imidacloprid) and it fails, you may administer Capstar treatments daily, as needed, for quick relief against a flea infestation. Capstar may also be used with flea shampoos, as well as heartworm preventives, antibiotics, vaccines and de-worming medications.
