PRODUCT INFORMATION
Capstar Flea Treatment Tablets for Cats and Dogs
Capstar is a fast-acting oral flea treatment containing nitenpyram. It is used to treat adult flea infestations in cats and dogs.
Capstar begins killing adult fleas within approximately 15–30 minutes of administration, with full effectiveness reached within 24 hours.
Please note: Capstar does not provide ongoing protection against fleas and does not treat flea eggs, larvae or pupae within the home. A suitable longer-lasting flea treatment and environmental flea-control programme may also be required to prevent reinfestation.
