Product Info:

IVERHART MAX® Soft Chew is a combination of three anthelmintics (ivermectin/pyrantel pamoate/praziquantel). The soft chews are available in four sizes in color-coded packages for oral administration to dogs according to their weight:

  • Purple box (6-12lbs)
  • Blue box (12-25lbs)
  • Green box (25-50lbs)
  • golden box (51-100lbs)


Dogs (8 weeks of age or older)


  • Affordable monthly protection against heartworms, roundworms, hookworms, and tapeworms
  • Satisfying chewy texture that makes heartworm prevention easy to give
  • Beef-free—safe for dogs with beef allergies
  • The only bacon-flavored soft chew for heartworm and other internal parasites

How it works:

For use in dogs to prevent canine heartworm disease by eliminating the tissue stage of heartworm larvae (Dirofilaria immitis) for a month (30 days) after infection and for the treatment and control of roundworms(Toxocara canis, Toxascaris leonina), hookworms (Ancylostoma caninum, Uncinaria stenocephala, Ancylostoma braziliense), and tapeworms (Dipylidium caninum, Teania pisformis).


Store at 60°F to 77°F (20°C to 25°C), excursions permitted between 59°F to 86°F (15°C to 30°C).

When replacing another heartworm preventative product in a heartworm disease prevention program, the first dose of IVERHART MAX® Soft Chew must be given within a month (30days) of the last dose of the former medication. A heartworm test should be performed prior to switching heartworm preventative products.

  • Remove only one dose at a time from the packaging
  • Return the remaining soft chew(s) to their box to protect from light
  • Can be offered to the dog by hand or added, intact, to a small amount of dog food
  • Make sure your dog eats the complete dose
  • Observed for a few minutes after administration to confirm that none of the doses has been lost or rejected ,if it is suspected that any of the dose has been lost redosing is recommended

Active Ingredients:

Soft Chew Size Ivermectin Content Pyrantel Pamoate Content Praziquantel Content
Toy (purple box) 34mcg 28.5mg 28.5mg

For use in dogs only. Keep this out of reach of children and pets. If the interval between doses exceeds a month(30 days), the effectiveness of ivermectin can be reduced. Therefore, for optimal performance, the soft chew 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 MAX® Soft Chew and the recommended dosing regimen will minimize the opportunity for the development of adult heartworms.

Possible side effects:

Adverse reactions and serious side effects are rare, however, they can occur. In the case of a more serious side reaction, seek immediate veterinary attention. Serious reactions include vomiting, depression/lethargy, diarrhea, shaking, seizures, uncontrollable body movements, or unusual salivation.
