My pushing 30 pony mare was on vet grad(?) Bio-Iso-G Cortaflex for about 15 years, after developing mild arthritis in one ankle. Unfortunately, it became unavailable in Canada last year, and after speaking with several horse folk and a few vets, my choices seemed to be a small daily dose of Bute, or 1/4 Previcox pill.
I went with the Previcox; was instructed by main vet to give 5 days on/2 days off, which didn’t seem to jibe with the official dosing instructions. So, pony has been on daily Previcox for a couple of months. I’m wondering if a should give her a med vacay, or find an anti-ulcer med to pair with the Previcox?
(In the case of an Arabian who went a bit lame at 18, it took a while to diagnose her (in the early stage), and she was okay without a joint supplement for about 7 more years in retirement. Apparently one front knee was bone on bone arthritis, and the vet said bute was the only effective med.
Nevertheless I spent tons of $ trying various new joint products as they came to market, but nothing helped. In my mares last year or two (not in noticeable pain, but getting slower), my vet advised gram of bute in a.m., omeprazole noon, and gram bute p.m. This regimen worked, but was not designed for long term use.
Back to the pony, I’m wondering how other people have treated arthritis in older equines, and see if I need to consider any tweaks or ? Thanks for any advice or comments.
