Nuheart (Generic Heartgard) – Heartworm Prevention for Dogs

Nuheart is an effective and affordable alternative to other heartworm prevention treatments. It is known by many as the generic version of the popular Heartgard Plus. It controls the immature form of heartworms and protects dogs from heartworm disease for a full one month. The tablet contains the powerful active ingredient, ivermectin, and is designed in a tasty meat-flavored base that makes administration simple and easy.

Nuheart tablets are indicated for use in small, medium, and large-sized dogs falling under three weight ranges – 0-25 lbs, 26-50 lbs, and 51-100 lbs, respectively. These tablets are available in 6- and 12-dose packs and are suitable for use in dogs 6 weeks of age and older.

How it helps

Nuheart contains ivermectin, an antiparasitic ingredient that works by eliminating the early (larval) stages of heartworms before they mature into adult worms. By interrupting the life cycle within the first 30 days of infection, it helps prevent the development of heartworm disease. Regular monthly dosing ensures continuous protection and reduces the risk of long-term complications associated with heartworm infections.

Who it’s for

  • Dogs requiring monthly heartworm prevention
  • Dogs of all breeds and sizes (weight-based dosing available)
  • Dogs that prefer small, easy-to-administer tablets
  • Pet parents looking for a cost-effective alternative to branded treatments
  • Available for dogs in the following weight ranges:
    • Up to 25 lbs
    • 26–50 lbs
    • 51–100 lbs

Your veterinarian can help determine the correct dosage based on your dog’s weight and health status.

Why Pet Parents Choose It

  • Affordable alternative to branded heartworm preventives
  • Helps prevent heartworm disease with monthly dosing
  • Small tablet size for easy administration
  • Palatable meat flavour accepted by most dogs
  • Suitable for a wide range of dog sizes
  • Simple once-a-month routine for consistent protection
  • Targets heartworm larvae before they develop into adults

How to Use

  • Give one tablet once a month on the same day (or within a few days of that date).
  • Administer the tablet directly by placing it on the back of your dog’s tongue and ensuring it is swallowed.
  • Alternatively, dissolve the tablet in 5–10 ml of water or mix with food.
  • Ensure your dog consumes the full dose. If not, administer another full tablet.
  • Remove one tablet from the blister pack and store remaining tablets in a cool, dark place.
  • If a dose is missed, contact your veterinarian for advice and resume dosing promptly.
