"Tri-Heart Plus is a chewable, beef-flavored tablet administered once a month to protect your dog from the threat of potentially deadly heartworm disease, plus control against roundworms and hookworms. Dogs six months of age and older should be tested for heartworm disease prior to being put on a preventive program and tested annually thereafter.\r\n\r\nFor:\r\nDogs (at least 6 weeks of age)\r\n\r\nBenefits:\r\nTri-Heart Plus is used to prevent heartworm disease, treat and control roundworms and hookworms.\r\n\r\nActive Ingredients:\r\nIvermectin/Pyrantel\r\n\r\nCautions:\r\nAll dogs should be tested for existing heartworm infection before starting treatment with Tri-Heart chewable tablets. A mild hypersensitivity-type reaction, presumably due to dead or dying microfilariae and particularly involving a transient diarrhea has been observed in clinical trials with ivermectin alone after treatment of some dogs that have circulating microfilariae. 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. Make sure to tell your veterinarian what other medication you are giving to your pet. Quite often your veterinarian may prescribe two different medications, even if a drug interaction may occur. In this case, your veterinarian may vary the dose and/or monitor your pet more closely. This medication is generally well tolerated with other commonly prescribed medications. Contact your veterinarian if your pet experiences any unusual reactions when different medications are given together. Allergic reactions to medications may occur. Be sure to inform VetSource and your veterinarian if your pet has any known drug sensitivities or allergies. If your pet displays symptoms of an allergic reaction, call your veterinarian immediately or go to a veterinary emergency clinic. Symptoms may include but are not limited to: swollen lips, tongue, face, airways; difficulty breathing; agitation; profuse salivation; vomiting; widespread hives and itching.\r\n\r\n\r\nSide Effects:\r\nSide effects may include depression/lethargy, vomiting, anorexia, diarrhea, mydriasis, ataxia, staggering, convulsions and hypersalivation. Other side effects may occur. If you notice anything unusual, contact your veterinarian.\r\n\r\nUsage:\r\nTri-Heart Plus should be given orally as directed veterinarian."^^<http://www.w3.org/2001/XMLSchema#string>
