Tri-Heart Plus (ivermectin/pyrantel) chewable tablets are for use in dogs 6 weeks and older to prevent canine heartworm disease and for the treatment and control of roundworms and hookworms. Tri-Heart Plus contains ivermectin/pyrantel, the same proven active ingredient for heartworm protection and internal parasite control as the leading competitor, but at a lower price. A simple and palatable monthly, chewable tablet protects by killing the larvae before they reach a dog's heart. Beef flavor.
Each chewable tablet contains: Up to 25 lbs - 68 mcg ivermectin and 57 mg pyrantel; 26 to 50 lbs - 136 mcg ivermectin and 114 mg pyrantel; 51 to 100 lbs - 272 mcg ivermectin and 227 mg pyrantel.
Directions: Tri-Heart® Plus ivermectin/pyrantel chewable tablets should be administered orally at monthly intervals at the recommended minimum dose level of 6 mcg of ivermectin per kilogram (2.72 mcg/lb) and 5 mg of pyrantel (as pamoate salt) per kg (2.27 mg/lb) of body weight
