CAPSTAR Green an adult female flea can lay up to 2,000 eggs in her lifetime. With CAPSTAR by NOVARTIS, almost all your dog's or cat's adult fleas will be gone within four hours.

How to Use

A single dose of Capstar (nitenpyram) 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. 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.


Active Ingredients: Nitenpyram

Very helpful for fighting fleas
November 5, 2014
I learned about Capstar while volunteering at my local animal shelter and was so happy to find it here. It truly does kill the fleas within 24 hours, which is especially useful for pets with flea allergy dermatitis. My dog really suffers in the summer from fleas and using a topical treatment monthly and Capstar in between for when he gets really itchy has definitely helped him.
ProsWorks quickly and thoroughly
ConsThe pet can get very jumpy when the fleas start dying. (But that stops after a few hours.)

My dog was having a terrible time when we moved to Florida. Baths, treatments and oils did not work for more than a day.
Upon a recommendation, I gave one to my dog Max. The next day he stopped scratching and there were numerous dead
fleas in his bed. I give him one every two weeks without ill effects. I recommend it to everyone who has pets.
ConsNone yet after 4 months
