Selamectin is the active ingredient found in multiple products including: Revolution For Dogs, Revolution for Cats, Selarid for Dogs, Selarid for Cats, Revolt for Cats, Revolt for Dogs, Senergy for Cats, and Senergy for Dogs. Selamectin is used in dogs and cats to prevent heartworm disease and treat and control flea and ear mite infestations. In dogs, Selamectin also controls tick infestations of the American dog tick and treats sarcoptic mange. In cats, it also treats intestinal roundworm and hookworm infections. Medications containing Selamectin are applied to the skin and are absorbed with the natural oils secreted by their skin. Selamectin kills parasites by interfering with the nervous system of the infecting parasite and provides 1 month (4 weeks) of protection from parasites.
Selamectin is also used in combination with other medications to provide additional parasite protection for dogs and cats. Revolution Plus for Cats pairs two active ingredients, Selamectin and sarolaner. Revolution Plus offers broad-spectrum protection from 6 different internal and external parasites: fleas, ear mites, roundworms, hookworms, black-legged ticks (deer tick), American dog ticks, and gulf coast ticks. Revolution Plus also prevents heartworm disease in cats. It is applied topically to the skin and provides 1 month (4 weeks) of protection from parasites.
It is always recommended to speak with your veterinarian about the right parasite preventative product for your dog or cat's needs. Your veterinarian can recommend the best product for your dog or cat based on your location and the type of parasites they may encounter. Products containing Selamectin require a prescription from a veterinarian because of their ability to prevent heartworm disease. The American Heartworm Society and most veterinarians recommend an annual heartworm test before prescribing a heartworm preventative for your dog or cat.
