I’ve used it twice. One is a horse with a severe bone bruise in the coffin bone – vet actually suggested Tildren along with other treatment but I opted for the cheaper Osphos (which he thought was a good alternative). Can’t say for sure if it did anything or not as the horse is still lame after 6 months of rest. The only way to “see” what is happening would be to do another MRI of the foot, which won’t be happening.
Other horse has cervical arthritis that has responded to injection in the past, but he’s IR/EMS and I was reluctant to put any steroids into him again so we tried Osphos to see if it would help. He also had stifle OCD surgery that has needed injections in the past, so there was some hope the Osphos might do some good without risking steroid injections. I think it did help him some – it wasn’t as dramatic as the change when we injected his neck, but he did improve.
Cost was something in the neighborhood of $370 for the Osphos, plus farm call. One of them did get slightly colicky not long after injecting and was resolved by walking for a bit. My vet said if they were going to react like that, it would be fairly quickly, like in the first 4 hours or so post-injection, so we had timed it so he’d be here doing other work or in the neighborhood at another farm. But I did not need to do more than walk the one.
