Yes I was on it for 12 months and lost a bunch of weight due to nausea. My Dr and I both feel it was working. After my body got rid of the Imuran I felt like I was 21 again. That only lasted a couple of weeks. I hope Imuran works for him. I'm now on Cellcept and just sorta stable. Haven't had to have IVIG for a year now so it must be helping. I'm almost off Prednison after 5 years. Please remember we are all different and each of us react different to each drug. I also take mestinon daily but appears to have little effect.
