How long is it ok to take preds? I've been on them at varying doses since 2003, with one break for a few months. The lowest dose when on them was 10mg, highest was 40mg as far as I can recall. I've been on them continually for over two years now. I've had bone density tests and I've been assured everything's fine. I did try a special non absorbent type a month ago which didn't seem to work for me, so changed back two weeks ago. I'm still having a flare up with loads of blood and mucus numerous times a day and severe cramping. My doctor says it's ok to be on them, he's like to get me off them but everything he's tried hasn't worked.
