How PetArmor CapAction Works

PetArmor CapAction uses nitenpyram, a proven flea-killing ingredient that enters your dog's bloodstream after administration. Adult fleas are killed when they bite your pet, providing fast relief from active flea infestations. Most pet owners notice a significant reduction in fleas within just a few hours of treatment.

This flea treatment tablet is ideal for situations where immediate flea elimination is needed, such as before grooming, boarding, traveling, or introducing a new pet into the home.

Recommended Use

Administer one tablet orally to dogs weighing between 2 and 25 lbs. The tablet may be given directly by mouth or mixed with a small amount of food. Follow package directions carefully and consult your veterinarian if you have questions regarding flea treatment or prevention.
