IVERHART Plus (ivermectin/pyrantel) Flavored Chewables 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.

This heartworm medication is recommended for dogs 6 weeks of age and older. For dogs over 100 lbs use the appropriate combination of these flavored chewables.


Remove only one flavored chewable at a time from the foil-backed blister card.

Because most dogs find IVERHART Plus heartworm medication palatable, the product can be offered to the dog by hand. Alternatively, it may be added intact to a small amount of dog 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 of this pet meds to ensure that part of the dose is not lost or rejected. If it is suspected that any of the doses has been lost, redosing is recommended.

IVERHART Plus for dogs 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 prevention program, the first dose of IVERHART Plus dog medication 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 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 IVERHART Plus Flavored Chewables and resumption of the recommended dosing regimen will minimize the opportunity for the development of adult heartworms.

Monthly treatment with IVERHART Plus pet meds also provides effective treatment and control of ascarids in dogs and hookworms in dogs. Clients should be advised of measures to be taken to prevent reinfection with intestinal parasites.


This parasite treatment for dogs when given orally using the recommended dose and regimen, are effective against the tissue larval stage of D. immitis for a month (30 days) after infection and, as a result, prevent the development of the adult stage.

IVERHART Plus for dogs is also effective against ascarids in dogs and hookworms in dogs.


In a trial in client-owned dogs, IVERHART Plus Flavored Chewables were shown to be a palatable oral dosage form consumed at first offering by the majority of dogs.


All dogs should be tested for existing heartworm infection before starting treatment with IVERHART Plus Flavored Chewables which are not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with IVERHART Plus Flavored Chewables.

While some microfilariae may be killed by the ivermectin in IVERHART Plus Flavored Chewables at the recommended dose level, IVERHART Plus Flavored Chewables are 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.

Keep this and pet medicines 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.

In clinical trials with ivermectin in dogs, vomiting or diarrhea within 24 hours of dosing was rarely observed (1.1% of administered doses).

The following adverse reactions have been reported following the use of ivermectin in dogs: Depression/lethargy, vomiting, anorexia, diarrhea, mydriasis, ataxia, staggering, convulsions and hypersalivation.


Studies with ivermectin indicate that certain dogs of the Collie breed are more sensitive to the effects of ivermectin administered at elevated dose levels (more than 16 times the target use level of 6 mcg/kg) than dogs of other breeds. At elevated doses, sensitive dogs showed adverse reactions which included mydriasis, depression, ataxia, tremors, drooling, paresis, recumbency, excitability, stupor, coma and death. Ivermectin for dogs demonstrated no signs of toxicity at 10 times the recommended dose (60 mcg/kg) in sensitive Collies. Results of these trials and bioequivalence studies support the safety of ivermectin in dogs, including Collies, when used as recommended.

Ivermectin for dogs has shown a wide margin of safety at the recommended dose level in dogs, including pregnant or breeding bitches, stud dogs and puppies aged 6 or more weeks. In clinical trials, many commonly used flea collars, dips, shampoos, anthelmintics, antibiotics, vaccines and steroid preparations have been administered with ivermectin/pyrantel in a heartworm disease prevention program.

In one trial, where some pups had parvovirus, there was a marginal reduction in efficacy against intestinal nematodes, possibly due to a change in intestinal transit time.


IVERHART Plus Flavored Chewables are available in three dosage strengths (see Dosage section) for dogs of different weights. Each strength comes in a box of 6 tablets, packed 10 boxes per display box and in a bulk dispenser carton containing 20 cards of 6 tablets per card.
