Veterinarian Review (Michael Dym, VMD)

Interceptor plus ia a wonderful chewable monthly heartworm preventative pill that is easy to administer and comes in a convenient range of four weight categories. In recent years we have been seeing increasing amounts of beef allergies in our animal patients. Many of the heartworm preventative medications over the years have been made with beef flavoring, which can be a problem in many allergic dogs. There have been also increasing demands by clientele to include additional monthly protection against other intestinal worms, especially tapeworms, which are often carried by fleas and/or transmitted from the feces of other animals, and which may cause hidden digestive tract disease in affected animals. With the addition of praziquantel, this product provides this additional protection. The versatile main ingredient milbemycin, not only prevents heartworms, but treats, controls and prevents most other intestinal worms, including roundworms, hookworms, and whipworms, with the latter parasite, being very difficult to rid dogs of, making prevention a key for this pesky intestinal parasite. Most dogs readily accept this tasty chicken-flavored chew, with only a rare dog having a mild digestive tract reaction in my experience. Given the broad spectrum coverage and efficacy of this complete monthly worm preventative, I give this product an overall rating of a 4.5 (out of 5), with an ease of administering of 5 (out of 5).

Given the rapidly expanding world of generics in the human pharmaceutical industry, it is indeed a pleasure for me as a practitioner of 16 years or experience to also see the same cost saving but equally as effective alternatives in the veterinary field as well. Heartworm disease is on the increase again in the United States. And given the importance and sometimes difficulty of client compliance in keeping up with costly monthly heartworm preventative medicines, it is great that Merck Animal Health has offered a generic version like Tri-Heart Plus to help meet this continued threat. Hopefully the savings on this preventative will encourage even more clients to have their pets on year round internal parasite control against the year round threat of heartworms, roundworms and hookworms. Tri-Heart Plus is quite safe in as pups as young as 6 weeks of age, as well as pregnant and nursing dogs. While I would rather have seen a beef flavored chewable over the pork flavor, dogs seem to love this pill just the same. The only disadvantage I have seen is very rare digestive upset in some patients which could be from the ivermectin or pyrantel main ingredients, or possibly from the pork flavoring.
