Reliable & Recommended.

A heartworm-positive diagnosis is upsetting news, but we’re here to help. Along with guidance from your veterinarian, we’ll provide the information and support you’ll need to get through this—together.

Melarsomine dihydrochloride, the active ingredient in DIROBAN®, is the recommended treatment therapy for heartworm disease in dogs.1 A veterinary trusted source, DIROBAN helps dogs return back to their normal lives as soon as possible.

  • Melarsomine dihydrochloride is the preferred treatment for heartworm disease by the American Heartworm Society and Companion Animal Parasite Council.
  • The sooner adult and immature worms are killed, the sooner your patient and client return to their normal lives.
    Helps preserve the human-animal bond by shortening the recovery time over slow kill.
  • Zoetis provides clinics and pet owners with support to help educate and manage heartworm treatment expectations.
