Product Information

Your dog can go anywhere without the risk of becoming infected with heartworm disease if you give him/her Heartgard Plus monthly!

What is Heartgard Plus?The worming medications in Heartgard Plus help to control and treat certain intestinal parasites (roundworms and hookworms) while effectively preventing heartworm in dogs. Ivermectin and Pyrantel pamoate work together in order to help protect your dog from heartworm disease, roundworms, and hookworms.

Formulated for: dogs and puppies unless he/she is under 6 weeks of age. A pregnant/breeding female should be able to tolerate this medication safely if necessary.

How is this medication given? It is recommended to administer Heartgard Plus to your dog on a monthly basis. Tablets should not be swallowed whole and should be chewed. You may need to break tablets in small pieces if your dog has the tendency to swallow without chewing.

It is essential to give tablets during the mosquito season (spring/summer) in order to protect your dog from heartworm disease although many veterinarians recommend using tablets year-round. Speak with your veterinarian to find out what he/she recommends for your dog. The first dose must be given within 30 days of the dog's first exposure to mosquitoes and the last dose must be given within 30 days after the dog's last exposure to mosquitoes if you are using Heartgard Plus seasonally.

A blood test to check for heartworm disease is typically mandatory prior to starting your dog on Heartgard Plus. Variables such as prevalence of heartworm disease in the area, missed or late doses of heartworm preventative, and your dogs lifestyle will determine the frequency of heartworm testing. Your veterinarian is the best person to talk to regarding the frequency of heartworm testing.

Only give this medication to the dog for which it has been prescribed. Do not split tablets and give each dose exactly as directed by your veterinarian. Do not double dose. If you miss a dose, check with your veterinarian before restarting your dog on Heartgard Plus.

  • Provides protection against heartworm disease that can be potentially deadly to your dog.
  • Helps treat and control roundworms and hookworms in addition to providing heartworm protection.
  • Flavored chewable formulation makes administration simple and appealing to your dog.
  • Monthly dosing makes it easy to give medication regularly.

Uses: Heartgard Plus is a chewable tablet that is given once a month in order to prevent heartworm disease and control and treat hookworms and roundworms which are common intestinal parasites that can sometimes cause problems in dogs.

Possible Side Effects: Heartgard Plus is generally safe but may cause some side effects including vomiting and diarrhea. Incoordination, convulsions, and drooling are rare but possible especially if this medication is given at high doses. Contact your veterinarian immediately if your dog displays any unusual symptoms once he/she starts this medication.

Drug and Food Interactions: Tell your veterinarian if your dog is taking any medications, including vitamins, supplements, and other heartworm medications because interactions are unlikely but may be possible. No known food or drug interactions have been reported with Heartgard Plus.

Precautions: Collies and other herding breeds should take this medication cautiously. If your veterinarian has prescribed this medication to any of these breeds, you should monitor your dog closely for at least 8 hours after giving this medication for weakness, staggering, dilated pupils, trembling, drooling, or pressing the head against a wall. Contact your veterinarian immediately if you see these signs. This medication should not be given to puppies less than 6 weeks of age. Heartworm testing is mandatory prior to starting Heartgard Plus. Your veterinarian is the best person to ask regarding testing recommendations.

    Comments about Heartgard Plus Chewable Tablets for Dogs 26-50 lbs:

    I give this monthly to my dog to prevent any heartworm disease. Since my dog has not had any heartworm issues since the day I started giving this to her (2 years ago) then I count this as a successful product!
