Capstar is safe to use in pregnant or breeding animals. Capstar is fast acting and begins to kill adult fleas on the pet within 30 minutes and the effect lasts for 24 hours. Pets may scratch as a result of the fleas dying. It is not a reaction to the medication itself. There are no known drug or food interactions. Capstar treats the pet only. To properly control fleas all pets must be treated and the outside and inside environments also need to be treated to prevent a reoccurrence.

Active Ingredients

CAPSTAR Tablets contain 11.4 or 57.0 mg of nitenpyram, which belongs to the chemical class of neonicotinoids. Nitenpyram kills adult fleas.

Directions

CAPSTAR Tablets kill adult fleas and are indicated for the treatment of flea infestations on dogs, puppies, cats and kittens 4 weeks of age and older and 2 pounds of body weight or greater.

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 per day.

To give CAPSTAR Tablets, place the pill directly in your pet's mouth or hide it in food. If you hide the pill 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.

Treat all infested pets in the household. Fleas can reproduce on untreated pets and allow infestations to persist.
