Heartgard Plus Green (ivermectin/pyrantel embonate) is a medication used in dogs to prevent canine heartworm disease by eliminating the tissue stage of heartworm larvae (Dirofilaria immitis) for a month.

Heartworm disease is a potentially fatal condition caused by parasitic worms transmitted to dogs through infected mosquitoes.

The larvae of these worms develop under the skin and migrate to the blood vessels of the heart and lungs, where they grow into adults and cause severe damage.

Long-term effects of heartworms in dogs include damage to the vessels of the lungs, heart, and arteries, which can impact the dog’s health and quality of life even after the parasites are gone.

Heartgard Plus Green contains two active ingredients: ivermectin and pyrantel. Ivermectin is a broad-spectrum antiparasitic medication that is effective against heartworms. Pyrantel is used to treat roundworm, hookworm, and stomach worm parasites in dogs.

Use and Dosage

The dosage of Heartgard Plus Green for dogs is typically based on their body weight. The recommended dosage is ivermectin 6 micrograms/kg and pyrantel 5 mg/kg of body weight, given once a month. Follow the dosing instructions provided by your veterinarian or the product label.

Heartgard Plus Green is available in chewable form and is typically administered orally. Give the medication as directed and continue regular monthly administration to ensure effective prevention of heartworm disease.

Side Effects

Common side effects include:

  • Vomiting, diarrhea, or a temporary loss of appetite may occur in some dogs
  • Tremors, dilated pupils, or incoordination may occur in rare cases, especially at higher doses

Note that these side effects are generally mild and transient. If you notice any unusual or severe side effects after administering Heartgard Plus Green to your dog, consult your veterinarian for further guidance.


  • All dogs should be tested for existing heartworm infection before starting treatment with Heartgard Plus as it 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 transient diarrhea, has been observed in clinical trials with ivermectin alone after treatment of some dogs that have circulating microfilariae.
  • Keep this and all drugs out of the reach of children. In case of ingestion by humans, clients should be advised to contact a physician immediately. Physicians may contact a Poison Control Center for advice concerning cases of ingestion by humans.
  • Store between 68°F° – 77°F (20° – 25°C). Excursions between 59°F – 86°F (15° – 30°C) are permitted. Protect product from light.
