Any dog, anywhere, any time can be infected by potentially deadly heartworms.

For years, dog owners have protected their pets from heartworms, roundworms and hookworms with IVERHART PLUS^® (ivermectin/pyrantel). Now, IVERHART MAX^® (ivermectin/pyrantel pamoate/praziquantel) takes this powerful, proven treatment to the next level to give your pet the most complete protection available against heartworms and common and potentially zoonotic roundworms, hookworms, and now, tapeworms. IVERHART MAX^® is formulated with the trusted actives veterinarians have prescribed for years in one convenient chewable tablet.

Easy to give. Once a month will keep your dog safe and healthy...for life.


IVERHART Products are well tolerated. All dogs should be tested for heartworm infection before starting a preventive program. In clinical field trials, the most common adverse reactions, vomiting and diarrhea, were rarely observed (1.1% of doses administered). For more information, ask your veterinarian. The safe use of IVERHART MAX^® has not been evaluated in pregnant or lactating dogs. See package insert for full disclosure.
