Selamectin is the main ingredient, and side effects, while rare, may include digestive upset and hair loss, and rarely, dermatitis at the application site.

Main rival products for dogs may include Heartgard by Merial, or Interceptor by Novartis for heartworms, Frontline by Merial, or Program by Novartis for fleas, or Sentinel (a mix of Program and Interceptor) by Novartis for both.

Generally Revolution is prescribed for cats and smaller indoor dogs due to studies that have shown it does not work as well to prevent heartworms as some of the oral preventatives^{[citation needed]}.
