Selamectin is effective against a number of gastrointestinal roundworms and external parasites such as fleas, lice, mites (Sarcoptes, Otodectes, Notoedres) and a few tick species. Besides, it works in the prevention of heartworm disease.
After topical application, selamectin has high affinity for sebaceous glands and skin. Do not bath your dog 48 hours before or 48 hours after the application because the product's effectiveness decreases.
