Revolution is a safe and simple monthly topical medication used to protect your pet from heartworms, fleas, and ear mites. It also protects dogs from ticks and sarcoptic mange and cats from roundworms and hookworms. Revolution requires a prescription from your veterinarian. (Example: 3 Pack = 3 doses which lasts 3 months.)
How it works: Revolution works by penetrating the skin and entering your pet's bloodstream. Concentrations of selamectin, the active ingredient, in the tissue and bloodstream prevent heartworm disease. Selamectin also redistributes into the skin from the bloodstream and kills adult fleas, American dog ticks, and ear mites, and prevents flea eggs from hatching. It is also an anthelmintic, which means it fights to expel parasitic worms. Parasites ingest the drug when they feed on the animal's blood.
