Tri-Heart Plus is used in the prevention of heartworm infection and the control and treatment of various other worm infections. Tri-Heart Plus contains two active ingredients: ivermectin, which interferes with the parasite's nerve transmission, causing paralysis and death of the immature heartworms (larvae), and Pyrantel pamoate, which also interferes with the parasite's nerve transmission, causes paralysis and death of intestinal worms.

|Pyrantel||57 mg||114 mg||227 mg|
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. The recommended dosing schedule for prevention of canine heartworm disease and for the treatment and control of ascarids and hookworms is as follows:
Remove only one chewable tablet at a time from the blister card. Because most dogs find Tri-Heart® Plus chewable tablets palatable, the product can be offered to the dog by hand. Alternatively, it may be added intact to a small amount of dry food or placed in the back of the dog's mouth for forced swallowing.
Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that part of the dose is not lost or rejected. If it is suspected that any of the doses have been lost, redosing is recommended.

|26-50 lbs||Give 1 chewable every month (Tri-Heart Plus Green)|
|51-100 lbs||Give 1 chewable every month (Tri-Heart Plus Brown)|
|Over 100 lbs||Give combination of chewables based on weight|
Tri-Heart® Plus chewable tablets should be given at monthly intervals during the year when mosquitoes (vectors), potentially carrying infective heartworm larvae, are active. The initial dose must be given within a month (30 days) after the dog's first exposure to mosquitoes. The final dose must be given within a month (30 days) after the dog's last exposure to mosquitoes.
When replacing another heartworm preventive product in a heartworm disease preventive program, the first dose of Tri-Heart® Plus chewable tablets must be given within a month (30 days) of the last dose of the former medication.
If the interval between doses exceeds a month (30 days), the efficacy of ivermectin can be reduced. Therefore, for optimal performance, the chewable tablet must be given once a month on or about the same day of the month. If treatment is delayed, whether by a few days or many, immediate treatment with Tri-Heart® Plus chewable tablets and resumption of the recommended dosing regimen minimizes the opportunity for the development of adult heartworms.
Monthly treatment with Tri-Heart® Plus chewable tablets also provides effective treatment and control of ascarids (T. canis, T. leonina) and hookworms (A. caninum, U. stenocephala, A. braxiliense). Clients should be advised of measures to be taken to prevent reinfection with intestinal parasites.
