Just thought I would post an update for anyone interested…
It turns out that the Previcox is most likely not the cause of my horse’s elevated liver enzymes. I did take him off it for several days and discovered that it was covering up mild laminitis. That discovery sent us searching in a different direction. Long story short, I got a second opinion from a different vet and the horse is negative for IR and many other conditions but strongly positive for cushings (PPID). This vet believes that the PPID is the cause of all his health problems. He is currently back on the Previcox and starts the Prascend tomorrow. We will recheck all the bloodwork in a month to see how he is responding to the medication.
The one thing I have to say is that I’m astounded by how well the Previcox works. I was absolutely amazed at how sore my horse was off it and how quickly he seemed better once I started using it again. I honestly wouldn’t have believed it if I hadn’t seen it with my own eyes. In many ways, it was really interfering with getting an accurate diagnosis because it covered up some very key symptoms. Regardless, I’m simultaneously glad it helps so much because my horse is pretty sound when he’s on it.
Thanks for all of the feedback, hopefully my horse will feel much better once the Prascend starts working!
