Bella, sorry, sounds frustrating.
I just came off of a very long remission and got spoiled, as I almost forgot how gripping this disease can be. Upon looking at my lab work, the doc said that I wasn't metabolizing my azathioprine effectively. He put me on allopurinol to boost the performance of my azathioprine. I've cut my dose of azathioprine in half and am in the process of getting my levels in order. I'm only 3 weeks into this process. Fingers crossed.
I'm dealing with a stubborn flare and am stuck on 40mg of prednisone and corticosteroid enemas right now. I'll let you know if I find some relief from it.
