I've been taking for months now but it doesn't feel like it's making a difference. Consultant says to give it time, but not giving an indication of how long. I was diagnosed in Sep 2011 and steroids made a quick improvement. I then went on azathioprine and was able to reduce steroids. I really felt a positive change but it didn't agree with my liver. I've had to increase steroids since taking Mycophenolate and also seen a resurgence of symptoms that had gone. I'd appreciate hearing anyone's experience please? Thanks.
