Ahh Prednisone, the best and worst drug there is out there.
I have been on it since early October and tend to respond pretty well to it but for some reason this time I got down to 5 mg and started to flare again. Very frustrating. I called my Gastro guy and he put me on 50 mg of Azathioprine daily which seems to have helped. I'm about 4 days away from getting of the Prednisone all together and am feeling 99%.
I haven't actually had a dicussion with my doctor about the Azathioprine (all this has been done over the phone) but so far I haven't had any notable side effects. It looks a little scary on paper and I'll admit I was a little freaked out when the pharmarcist dropped everything and asked what I taking it for, but so far the results by far outweigh potential side effects.
Ask your doctor about it - and again I haven't had a lengthy discussion about it with my doctor but so far it seem to have helped.
