Iverhart Plus Basics

Iverhart Plus kills a number of parasites and prevents parasitic diseases. It effectively treats heartworms, microfilaria (the offspring of heartworms), hookworms, and roundworms. The active ingredients are ivermectin and pyrantel pamoate. Ivermectin and pyrantel pamoate work together to control a wide spectrum of parasites by causing neurological damage to the parasites.

Iverhart Plus requires a prescription from your veterinarian. It comes in an easy to administer, chewable tablet that is pork-liver flavored. It comes in various sizes according to your dog’s weight.
