Trifexis Side Effects

Added December 2012: This article has collected a LOT of comments from people concerned about Trifexis side effects. I am torn on how to report on this issue. The fact that hundreds of you feel that Trifexis has been harmful to your pet is disturbing. However, if Trifexis is causing these serious side effects then I should be able to find a lot of discussion about this on places like Veterinary Information Network where tens of thousands of vets talk about their cases, and I am not. If your pet has suffered Trifexis side effects then PLEASE have your veterinarian file a report with the FDA.  If there is a problem with the medication the only way the FDA will act is if they get enough reports of Trifexis side effects from veterinarians.

Does Trifexis have serious side effects? Is Trifexis safe? (more…)...
