If your dog is exposed to a visible flea outbreak, Capstar for Dogs can be a lifesaver. Formulated in a small tablet, it starts working fast and begins killing adult fleas within just 30 minutes of administration. This makes Capstar flea treatment an excellent solution when your canine friend needs immediate relief from fleas.
The Capstar tablet can be given directly to your dog by mouth. Alternatively, it can be hidden in their favorite food, making it easy to administer even to picky eaters. Capstar for fleas is safe for puppies from four weeks of age. This allows you to treat your juvenile rescued or adopted puppy, just before starting with a long-term flea prevention plan.
Capstar flea tablets for dogs contain nitenpyram as its active ingredient. After ingestion, this active ingredient is quickly absorbed into the dog's bloodstream. This active disrupts the flea's nervous system, causing the rapid death of fleas when they bite the treated dog. It starts killing adult fleas within 30 minutes of administration. In studies referenced in the label, Capstar provided more than 90% efficacy against adult fleas on dogs within approximately four hours.

| Large Dog | 25.1 – 125.0 | Green | 57.0 | One |
Capstar is not for use in humans. You should keep these tablets out of reach of children, pets, and uninformed people. Do not use Capstar in puppies under four weeks of age or less than two pounds of body weight. It is safe for pregnant or nursing dogs.

Capstar is a small oral tablet that provides faster relief from fleas. This formula is known to begin killing fleas in 30 minutes of administration.
Capstar provides fast relief by beginning to kill fleas within 30 minutes. According to studies referred to in the label, it showed more than 90% efficacy against adult fleas within 4 hours.
You may use Capstar daily or as required to help treat and control an existing flea infestation. You should use a regular long-term flea treatment for optimum flea control.
Capstar is recommended for active flea infestations on puppies and kittens from four weeks of age with at least two pounds of body weight. There are two formulations available for dogs and cats: Capstar Tablets for Cats and Small Dogs (2-25 lbs) and Capstar Tablets for Large Dogs (25.1-125 lbs).
One dose of Capstar tablet should kill the adult fleas on your pet. If your pet is re-infested with fleas, you can administer another dose as often as once per day.
After administering Capstar, the active ingredient, nitenpyram, causes hyperactivity in fleas just before killing them. This may cause your dog to scratch, which may subside as soon as fleas are killed.
Capstar has been shown to kill more than 90% of adult fleas within four hours on dogs and will continue to kill them for 24 hours. After this period, you will need a long-term preventive. Also, about 95% of the flea population includes the immature fleas (eggs, larvae & pupae) in your pet's environment. This means your pet is continuously exposed to flea infestations until you eliminate the environmental infestation. To achieve this, you should treat all pets in the household and wash your pet's bedding and other flea-prone areas in the home.
