What is Capstar for Cats and Dogs?

Give this medication as directed by your veterinarian. Your veterinarian will choose the package size appropriate to your pet's weight. Read and follow the label carefully.

A single dose will kill the adult fleas on your pet. If your pet gets re-infested with fleas, you may safely give another dose as often as once a day. Nitenpyram does not have an effect on fleas in the pet's environment. You may need to treat more than once because immature fleas in your pet's living space will continue to develop into adults that can re-infest your pet.

Nitenpyram works well with an insect growth inhibitor like lufenuron to prevent and control flea eggs from hatching.

Give this pill directly in your pet's mouth or you may hide it in food.

Ensure your pet consumes the entire dose. If it is not entirely consumed, it is safe to re-dose the full recommended dose as soon as possible.

Nitenpyram will begin to work within 30 minutes.

In multi-pet households, all pets should be treated for maximum effectiveness.

There is no successful flea control program that does not involve treating the environment. Discuss with your veterinarian what product to use in your pet's living space.
