This poster has posted this same question in three different threads she’s started, and has gotten the same answers every time. I’m really not sure what you’re looking for, Horses, with each additional thread with the same basic question and answers??
Scope the horse, look for ulcers. If you can’t do that, put the horse on ranitidine or an omeprazole that’s proven to be effective. Ask your vet how she has determined efficacy of the omeprazole she’s prescribing for your horse. If she doesn’t have a good answer (and that answer SHOULD BE “I have done scoping studies that have shown this to be effective”) then find a new vet. If you like her otherwise and don’t want to bother with finding a new vet over this issue, go to wal-mart and buy their ranitidine. Start the horse on it tonight. If you want to treat with omeprazole, then order from Abler today but ALSO start the horse on ranitidine now, as shipping from Abler can take some time.
If you want to treat the hind gut, use something that’s been proven to do that–and I don’t think l-glutamine on it’s own has? Equishure and Succeed are the general go-tos for that area of the gut. The Succeed people have a 2 month challenge where they will reimburse the cost of the product if it’s not effective. (Read through all the rules and such first, and save the boxes–someone here posted that you do need the UPCs off the box to get your refund.)
This is really not something to waffle on and not treat appropriately. You’re seeing behavioral issues and the horse isn’t eating–which is suggestive that his stomach is pretty bad. You can’t know for sure how bad he is without scoping, but horses CAN die from gastric ulceration if the ulceration is bad enough to hemorrhage. It’s an unlikely result, but a good reason to either scope the horse and see exactly what you’re dealing with, or to just treat the horse with an appropriate drug that’s proven to work.
You’ll notice that “proven efficacy” is a sticking point here. Omeprazole is degraded by the acid in the stomach and needs protection to get through that environment where it can be absorbed by the body. Without an effective buffer or coating, you’re throwing your money down the tubes. The only SURE THING with regard to omeprazole is GastroGard/UlcerGard, which is pricy but effective. There are various other compounded products and things produced by other companies that are very much a grey area–some have had good results (like the Abler products, lots of discussion here about their “blue pop rocks”) and some vets have done scoping studies on compounded products from certain pharmacies (I have a vet that’s done this.)
There are a whole lot of red flags coming through from your vet. It’s certainly up to you how to proceed, but keep in mind that treating for 2 weeks with a compounded product that hasn’t been proven to work (now we’re back to scoping studies) is basically a gigantic gamble…and I don’t think there is any research that will show two weeks of anything–even GastroGard–will be effective to treat a stomach full of ulcers.
