Simparica Trio is a pork liver-flavored chewable tablet administered once per month to protect your dog from heartworm disease, fleas, ticks, roundworms, and hookworms.
Simparica Trio (sarolaner, moxidectin, and pyrantel chewable tablets) is the first FDA-approved monthly chewable that protects your dog against heartworm disease, ticks, fleas, roundworms, and hookworms. Approved for puppies as young as eight weeks old and weighing at least 2.8 pounds, Simparica Trio begins working against fleas in just four hours and kills five types of ticks - including the deer tick that may cause Lyme disease. Just one tasty liver-flavored chew does the job of two or three parasite medications, and in a study nine out of 10 dogs ate Simparica Trio voluntarily.1 It can be given with or without food. Simparica Trio comes with a 100% satisfaction guarantee on protection. If you feel that Simparica Trio isn’t providing sufficient protection, please call Zoetis’ medical support team to discuss the satisfaction guarantee at 1-888-ZOETIS1. Trust the #1 heartworm disease preventative chosen by veterinarians2 and prescribed to over 7 million patients.3 Available by veterinarian prescription only.
