Dogs Heartworm Treatment & Preventative Medicine

Iverhart Max and Iverhart Plus are oral heartworm preventatives for dogs. In addition to preventing heartworm disease, Iverhart Plus treats and controls roundworms and hookworms. Iverhart Max pet meds have added praziquantel to eliminate tapeworm infestations. Iverhart is abailable in 6 and 12 month packs for small dogs 6-12 lbs., medium dogs 12-26 lbs., large dogs 25-50 lbs., and extra-large dogs 51-100 lbs.

Iverhart Max prevents and controls four types of the most common canine worm infections: heartworms, tapeworms, hookworms, and roundworms. It requires only one dose a month and the pork liver flavoring is appealing to most dogs, providing effortless administration.

Benefits of Iverhart Max:

  • Eliminates heartworms in the tissue stage
  • Helps prevent canine heartworm disease
  • Terminates and controls tapeworms, hookworms, and roundworms
  • Flavored chewable tablets dogs like to eat
  • Once monthly dosing for convenient long-term protection
  • Side effects are rare and minor in most instances

Iverhart Max is only for dogs and puppies at least 8 weeks of age and weighing at least 6 lbs. Not for human use. Not for cats or any dog for which it was not prescribed.

Keep out of reach of children. Do not allow children to administer Iverhart Max. Read directions and precautionary statements before use.

Use only as prescribed by your veterinarian.


  1. Give your dog one chewable tablet of the prescribed dosage based on your dog's weight.
  2. Remove only the immediate dose from its blister pack and return the remaining product to its package.
  3. Feed the Iverhart Max chewable tablet by hand to your dog. Its pork liver flavor makes this easy in most instances. You may also add the tablet intact to your dog's food. If necessary, place the tablet in the back of your dog's mouth and trigger forced swallowing.
  4. Monitor consumption to be sure your dog takes the entire dose.

Frequency of Use:

Give your dog one Iverhart Max chewable tablet per month, on the same day each month. If you miss the scheduled date, give the dose as soon as you remember it. However, if it is nearly time for the next dose, wait; never give a double dose of Iverhart Max. Your veterinarian may prescribe Iverhart Max for year-round use or for use just during mosquito season. In the latter case, give the first dose within 30 days of your dog's first exposure to mosquitoes, and the last dose no more than 30 days after your dog's final exposure to the biting insects.
