## Description

Description Your furry friend must have a current heartworm test result on file with your veterinarian in order to be prescribed heartworm medication. Please visit your veterinarian to have this test performed annually to protect your four-legged friend. Tri-Heart Plus is an easy-to-feed chewable tablet prescribed to help keep your dog free of heartworm and other dangerous parasites. When given monthly, this simple and palatable tablet helps to protect your pet by killing the larvae before they reach your dog's heart. Best of all, the tasty tablets can be fed just like a treat! Your pet won't even know you're working to protect their heart. Uses Tri-Heart Plus is a monthly chew indicated to kill heartworm larvae and to control/treat adult hookworms and roundworms. Possible Side Effects Tri-Heart Plus is safe and has caused no side-effects in most dogs, but upset stomachs have been reported. Incoordination, convulsions, or drooling have also been reported rarely. Always contact your veterinarian if your pet appears sick or behaves strangely after taking Tri-Heart Plus. Drug & Food Interactions Talk to your veterinarian about any other drugs your dog is taking before starting Tri-Heart Plus. Precautions All dogs should be tested for existing heartworm infection before starting treatment with Tri-Heart Plus, which is not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program. Tri-Heart Plus is not indicated for dogs younger than 6 weeks old. Herding breeds (such as Collies) can be sensitive to the active ingredient, so talk to your veterinarian if your dog may be affected. If you miss a dose, your dog needs a blood test to resume your normal doses safely. Notify your veterinarian if you've skipped a dose or have any concerns. Keep this and all drugs out of the reach of children. Prescribing Information See all items by Tri-Heart Plus Watch our Tri-Heart Plus video Item Number 146101 Common Brand Name(s) Tri-Heart Plus, Heartgard Plus Dosage Measure 30 days For Use With Dogs Generic Name Ivermectin, Pyrantel Pamoate Brand Merck Breed Size Large Breeds Product Form Chewable Tablet Health Condition Heartworms, Hookworms, Roundworms Drug Type Parasiticide Ingredients Ingredients Active Ingredients: Ivermectin/Pyrantel Instructions Recommended Dosage 1 chew Storage Instructions Store at controlled room temperature of 59° - 86°F. Protect product from light. 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 dose has been lost, redosing is recommended. Tri-Heart® Plus chewable tablets should be given at monthly intervals during the period of 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 c
