Indications: Heartgard® Plus prevents Heartworm disease in dogs by eliminating the tissue stage of heartworm larvae (Dirofilaria immitis) for a month (30 days) after infection and also treats and controls ascarids (Toxocara canis, Toxascaris leonine) and hookworms (Ancylostoma caninum, Uncinaria stenocephala, Ancylostoma braziliense). Heartgard® Plus should be given at monthly intervals when mosquitoes 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. For optimal performance, Heartgard® Plus must be given once a month on or about the same date. If treatment is delayed, either by a few days or many, start immediate treatment with Heartgard® Plus and resume the recommended dosing schedule to minimize the opportunity for the development of adult heartworm.
When replacing another Heartworm preventative product in a Heartworm disease preventative program, the first dose of Heartgard® Plus must be given within a month (30 days) of the last dose of the former medication.
All dogs should be tested for existing Heartworm infection prior to starting treatment with Heartgard® Plus which is not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with Heartgard® Plus.
While some microfilariae may be killed by the Ivermectin in Heartgard® Plus at the recommended dose level, Heartgard® Plus is not effective for microfilariae clearance. A mild hypersensitivity-type reaction, presumably due to dead or dying microfilariae and particularly involving a transient diarrhea, has been observed in clinical trials with Ivermectin alone after treatment of some dogs that have circulating microfilariae.
Monthly treatment with Heartgard® Plus is also effective against canine ascarids (T. canis, T. leonine) and hookworms (A. caninum, U. stenocephala, A. braziliense).
Heartgard® Plus is for use in dogs six weeks of age and older. The monthly recommended minimum dose level is 6 mcg of Ivermectin per kg (2.72 mcg/lb) and 5 mg of Pyrantel (as pamoate salt) per kg (2.27 mg/lb) of body weight. Choose from three dosage strengths; dogs up to 25 lbs, dogs from 26 to 50 lbs, and dogs from 51 to 100 lbs. of body weight. For dogs over 100 lbs use the appropriate combination of these chewables. Each strength contains six chewables per package. Made in USA.

Studies have shown that Collie breeds are more sensitive to the effects of elevated doses of Ivermectin much higher than needed for heartworm prevention. If your dog shows any signs of hypersensitivity such as weakness, clumsiness, dilated pupils or trembling, bring to your veterinarian immediately.
All dogs should be tested for heartworm infection before treatment. Infected dogs must be treated before starting a prevention program with Heartgard® Plus.
