Administration

Use with Other Medications 
If your pet is currently receiving a monthly or longer-lasting flea preventative medication but still becomes infested with fleas, it is safe to administer Capstar to address a flea infestation. 
 
Capstar may also be used together with other products, including heartworm preventatives, corticosteroids, antibiotics, vaccines, deworming medications, and shampoos. Store at controlled room temperature, between 59 and 77 degrees F (15 - 25 degree C). 
 
Re-infestations 
Capstar kills adult fleas on dogs and cats, offering quick relief for your furry friend. While Capstar works fast to kill adult fleas and alleviate a current infestation, a subsequent preventative solution is recommended to prevent future re-infestations from any existing flea eggs and larvae in the environment. If you notice more fleas have found their way onto your dog or cat in the days following treatment, continue treating your dog or cat with Capstar with up to one dose per day.
 
Important Safety Information 
Capstar is safe to use in puppies and kittens 4 weeks of age and older, and 2 pounds of body weight or greater. Always read, understand, and follow the label and use directions.
