    About this product

    What is Iverhart Plus?

    Iverhart Plus Flavored Chewables are chewable tablets that, when given monthly, protect your dog from heartworm disease by eliminating the tissue stage of heartworm larvae (Dirofilaria immitis) for a month (30 days) after infection. They’re also used for the treatment and control of ascarids (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, Uncinaria stenocephala, Ancylostoma braziliense). Iverhart Plus requires a prescription from your veterinarian.

    For:

    Dogs 6 weeks of age or older

    Benefits:

    • When given monthly, provides year-round protection against heartworm, roundworm, and hookworm.
    • Eliminates heartworm larvae for 30 days after infection, preventing development of adult heartworm.
    • Easy to give, chewable tablet can be swallowed or chewed
    • Tasty pork liver flavor - give as a treat

    How does Iverhart Plus work?

    Iverhart Plus contains active ingredients ivermectin and pyrantel, antiparasitic drugs that can be used to prevent canine heartworm disease and prevent and treat hookworm and roundworm infections. It is effective against the tissue larval stage of D. immitis for a month (30 days) after infection and, as a result, prevents the development of the adult stage.

    Cautions:

    All dogs should be tested for existing heartworm infection before starting treatment with Iverhart PLUS Flavored Chewables, which are not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with Iverhart PLUS Flavored Chewables. While some microfilariae may be killed by the ivermectin in Iverhart PLUS Flavored Chewables at the recommended dose level, Iverhart PLUS Flavored Chewables are not effective for microfilariae clearance. A mild hypersensitivity-type reaction, presumably due to dead or dying microfilariae and particularly involving a transient diarrhea, has been observed in clinical trials with ivermectin alone after treatment of some dogs that have circulating microfilariae. Keep this and all drugs out of the reach of children. In case of ingestion by humans, clients should be advised to contact a physician immediately. Physicians may contact a Poison Control Center for advice concerning cases of ingestion by humans.
