Capstar is a tablet used to kill fleas on dogs and cats. Capstar begins working within 30 minutes and will kill more than 90% of adult fleas within 4 hours on dogs and 6 hours on cats. It is best used with a typical program such as Bayer Advantge, K9 Advantix, Merial Frontline Plus or Vectra 3D to prevent future flea infestations. Pets may scratch as a result of the fleas dying.
Cats (4 weeks of age and older and 2 pounds of body weight or greater)
Dogs (4 weeks of age and older and 2 pounds of body weight or greater)
How it works:
The active ingredient in Capstar is nitenpyram, an insecticide. This oral treatment kills adult fleas quickly. Nitenpyram interferes with nerve transmission in fleas, with no adverse effect on your pet.
