IVERHART MAX® Chew (ivermectin/pyrantel pamoate/praziquantel)

The Protection Dogs Need. Nothing They Don't.

  • Dog

Parasites are everywhere. (Just like your dog’s toys.) Give them the protection they need and nothing they don’t.

Leave the bells and whistles to the toys. When it comes to heartworm and internal parasite treatment and control, give your dog what it needs without going overboard. IVERHART MAX® Chew (ivermectin/pyrantel pamoate/praziquantel) provides coverage for 4 of the most common parasites — heartworms, hookworms, roundworms, tapeworms — all at a practical price.

IVERHART MAX® Chew is the only ivermectin-based, bacon flavored chew indicated for the prevention of heartworm disease caused by Dirofilaria immitis and for the treatment and control of roundworms (Toxocara canis, Toxascaris leonina), hookworms (Ancylostoma caninum, Uncinaria stenocephala, Ancylostoma braziliense), and tapeworms (Dipylidium caninum, Taenia pisiformis).
