I've been on Mobic (Meloxicam) for years; both pre and post gastric bypass.  The only problems I have with any oral meds is that they seem to go through my digestive system long before the medication is completely delivered into my system; ditto for vitamins, pain meds, anti-depressants.  I'm searching for something other than a patch (I'm allergic to the glue that sticks them on and that's where the drug is in the patch!), so I'm trying to find a cream, like bioidential hormones, that can be rubbed onto the skin and absorbed into the system that way.  Other than that, I'm going to have to try to find someting injectible; the needles don't bother me; I'd just rather do something that's not invasive.  If you hear of anything from your querry, let me know.  Good luck.
