    CAPSTAR Tablets are safe for pregnant or nursing dogs and cats.

    When using this product, you may notice that your dog or cat will start scratching itself as fleas begin to die. The scratching behavior is temporary and is a reaction to the fleas, not the drug. In very rare cases in cats, this may present as transient signs of hyperactivity, panting, vocalization and excessive grooming.

    CAPSTAR Tablets kill adult fleas that cause flea allergy dermatitis (FAD).

    CAPSTAR Tablets may be used together with other products, including heartworm preventives, corticosteroids, antibiotics, vaccines, de-worming medications, shampoos and other flea products.
