I am on Immuran since November 2011 and have not seen any real side effects. Haven't posted in a while because Jan. 15 I had emergency surgery for a perforated gangrenous gallbladder. I never had any symptoms that I know of proir to this. If not for the MG, I would be well now. It is taking me a long time to get my strength back. I had a terrible time convincing the nurses to call my neurologist and pulmonologist but they finally did and I was started on IV Neostigmine and Iv steroids. The nurses just don't know. My ph dropped to 7.25 and I had to be on bi-pap for about 48 hours(good old mg). It is by the grace of God that I am here today and I thank him for that.
