Valuheart Monthly Heartworm Tablets for Dogs


Pet Size

Don't know your pet's weight?

If you can't get them on the scale, try this super simple method:

  1. Weigh yourself.
  2. Weigh yourself holding your pet.
  3. Subtract the two numbers to get their weight.

Too heavy to hold? Your vet will weigh them if you ask (or may already have it on file if you call).

  • Description

    Valuheart is an OTC heartworm prevention for dogs available without a prescription. It is given to pets once a month and the active ingredient in the medication - Ivermectin - works to kill any worm microfilariae that are in their developmental stage in muscle and fatty tissue. Monthly dosing with Valuheart for dogs will keep your dog protected from heartworm infections at all times, and this is a nice reassurance for dog owners who are committed to their pet's health. Buy Valuheart from World Pet Express and get the best price on heartworm medication.

    What is Heartworm?

    Heartworm is a parasitic infection that affects dogs, cats, and other mammals. It is transmitted through mosquito bites, and the larvae migrate to the heart and lungs, causing serious damage. If left untreated, a heartworm can be fatal, but it can be prevented with regular medication and mosquito control measures.


    Valuheart tablets are packaged in differing dosage strengths based on the dog's weight. Choose from the 3 tablet sizes for up to 10kg (22 lbs), 11-20kg (23-44lbs), or 21 to 40kg (45-88lbs) based on your dog's approximate weight.

    Give the dog 1 tablet per month, at approximately the same time each month.

    For dogs over 88kg, you will give one Valuheart yellow (21-40kg) tablet plus half a table for every additional 20kg of body weight.


    The active ingredient in Valuheart heartworm tablets is Ivermectin.


    For dogs aged 6 weeks and up.

    Medication is only for use for heartworm prevention. For multi-spectrum anthelmintic parasiticide, you will need to use a different product.

    Medication is safe for pregnant or lactating dogs, but it is best to discuss its use with a veterinarian.

    Do not exceed proper dosage strength and never give your dog more than one heartworm preventative for dogs a month.

    Keep Valuheart for dogs in a cool, dry place, and be aware of the medication expiry date.


    There are no established drug interaction risks between Valuheart for dogs tablets and other OTC or Rx medications that a dog might be taking, but it may be best to speak with a veterinarian and let them know of all medications your dog is currently taking before proceeding to buy Valuheart online.

    Side Effects

    Side effects from using Valuheart are not common, but some dogs may experience gastrointestinal upset or be lethargic in days following taking the tablet. If side effects are seen it may be best to stop use and meet with a veterinarian again to discuss heartworm prevention medication alternatives.

    Frequently Asked Questions about Valuheart

    What is the active ingredient in Valuheart?

    Valuheart contains Ivermectin, which is the leading active ingredient in monthly heartworm prevention medication.

    Is Valuheart safe?

    Valuheart is safe and effective. Its safety has been proven for over two decades. When used as directed, Valuheart has a wide safety margin for all dogs, including stud dogs, breeding bitches (including pregnant and lactating), and puppies over 6 weeks of age.

    Is Valuheart effective?

    Valuheart prevents heartworm disease by eliminating the tissue stage of heartworm larvae (Dirofilaria immitis) that may infect the dog in the month (30 days) before treatment. However, it is not effective against adult-stage Dirofilaria immitis. Treatment may reduce the number of circulating microfilariae to undetectable levels.

    Can you split Valuheart tablets in half?

    Yes, you can safely split Valuheart tablets in half if required. The active ingredient Ivermectin is evenly distributed throughout the tablet, even though the tablets are not scored. Using a pill splitter ensures precise cuts.

    Can I mix Frontline Plus and Valuheart?

    Valuheart is specifically for heartworm prevention, while Frontline Plus is for flea and tick control. You can use them together, as they serve different purposes. Valuheart does not treat fleas or ticks, so combining it with Frontline Plus provides comprehensive protection.

    How to take Ivermectin?

    Ivermectin is typically administered orally. For specific dosing instructions, consult your veterinarian. It is essential to follow their guidance to ensure proper usage and safety.

    Does Ivermectin kill fleas?

    Ivermectin primarily targets heartworms and does not directly kill fleas. For flea control, consider using a separate product like Frontline Plus or another flea treatment.

    Does Ivermectin kill tapeworms?

    Ivermectin does not treat tapeworms. If your dog has tapeworms, consult your veterinarian for appropriate treatment options.

    How much Ivermectin to give a dog?

    Ivermectin dosage depends on your dog’s weight. Consult your veterinarian to determine the correct amount of Ivermectin for your specific dog.

    Does Ivermectin expire?

    Like any medication, Ivermectin has an expiration date. Always check the packaging for the expiration date and avoid using expired products.
