Treatment of flea infestations
Begins working within 30 minutes
For oral use
When you have a flea infestation, you need to kill fleas fast. Capstar is available without a prescription and starts killing fleas within 30 minutes so you don't have to wait. Unlike topicals, shampoos and sprays, Capstar is an oral tablet that starts working from the inside out. It is safe enough to administer daily to kill new fleas as they appear on your pet.
Capstar Tablets kill adult fleas and are indicated for the treatment of flea infestations on dogs, puppies, cats and kittens 2 pounds of body weight or greater and 4 weeks of age and older.
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.
*Capstar starts killing fleas within 30 minutes and achieves greater than 90% effectiveness against adult fleas within 4 hours for dogs and 6 hours for cats.
