Tri-Heart Plus Chewable Tablet for Dogs, up to 25 lbs, (Blue Box), 6 Chewable Tablets (6-mos. supply)

Tri-Heart Plus flavored chewable tablets are an FDA-licensed product, indicating they are safe and effective when used as recommended on the label. All dogs should be tested for existing heartworm infection before starting treatment with Tri-Heart Plus.

In clinical trials, many commonly used flea collars, dips, shampoos, anthelmintics (deworming medications), antibiotics, vaccines and steroid preparations have been administered with ivermectin/pyrantel in a heartworm disease prevention program. For questions about specific medications, please consult your veterinarian.

Ivermectin/pyrantel, the active ingredients in Tri-Heart Plus, have a wide margin of safety at the recommended dose level in dogs, including pregnant females, breeding males and females, and puppies 6 weeks or older, according to the package insert.

No. Tri-Heart Plus is labeled for use in dogs to prevent heartworm disease and not for the treatment of heartworm infections. The package insert contains this precautionary statement: “Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with Tri-Heart Plus flavored chewable tablets.”

No. Tri-Heart Plus is not approved for use in cats.

Medications, including Tri-Heart Plus, should never be administered after the expiration date. Studies have shown that Tri-Heart Plus will maintain its desired effectiveness when administered prior to the expiration date, when stored as recommended on the label.

Yes. The entire tablet should be administered as a single dose once each month. The smallest-sized Tri-Heart Plus tablet, in the blue-colored packaging, is labeled for dogs weighing 25 lbs or less. These tablets are scored to make it easier to break the tablet apart and have the small dog take the complete tablet but in smaller pieces at a time. Regardless of whether the tablet is broken apart or given the whole, the entire tablet should be given as a single dose.

Ivermectin/Pyrantel, the active ingredients in Tri-Heart Plus, have a wide margin of safety at the recommended dose level in dogs, including pregnant females, breeding males and females, and puppies 6 weeks old or more according to the package insert.

Contact your veterinarian immediately if accidental overdose occurs. To reduce the risk of accidental overdose in situations where more than one person may administer Tri-Heart Plus, we suggest ticking off the date on a specially marked calendar or making some other note to indicate that the dose has been given. Make a habit of checking with the other pet caregivers in your household before giving any medications to your pet.

For questions on specific medications, please consult with your veterinarian.

If the interval between doses exceeds 30 days, the efficacy of ivermectin can be reduced. Therefore, for optimal performance, the chewable tablet must be given once a month, on or about the same day of the month (Sign up for our email reminder service). If treatment is delayed, whether by a few days or many, please contact your veterinarian, as immediate treatment with Tri-Heart Plus chewable tablets and resumption of the recommended dosing regimen minimizes the opportunity for the development of adult heartworms.
