About Trifexis

We have had many questions about the series of articles written by the Indy Star on Trifexis and other veterinary drugs. We would like to address the concern of Trifexis safety that was the focus of the first article.

We have been prescribing Trifexis since it has been on the market and have found it be very safe and effective. The only side effects we have noted are vomiting, occasional diarrhea and, in rare cases, itching. Any medication taken orally can cause vomiting. For our patients that have experienced these side effects, they have been short-lived (24 hours or less) and, based on experience, we typically then decide to use a different heartworm preventive that may be better suited for these particular pets’ stomachs.

Meanwhile, I have continued to use Trifexis with my own pets because of its ease of administration, effectiveness and safety.

What we do know is heartworm disease kills. Period. Our greatest fear is that these articles will incite panic and cause people to stop giving preventives altogether. If you have questions about your pet’s heartworm medication or heartworm disease, please do not hesitate to ask your veterinarian or check out the American Heartworm Society’s website.

We doctors at Brownsburg Animal Clinic always welcome an open dialogue about your pet’s health, medications and any potential side effects. Your pet’s health and well being are always our top priorities. We thank you for your continued trust in allowing us to care for your furry family members.
