I'm glad that the other doctor is kicking your rheumy to get in gear with sorting out your RA meds. It isn't right that you're suffering so much! As far as Imuran goes I'm currently taking 150mg of it daily to treat ulcerative colitis and it's working fabulously. It takes up to 3 months to see the full effects but I was a quick responder to it and noticed improvement in 2 wks. My wbcs are just below the lowest normal which is where the doctor wants it to be. Hopefully an immune suppressant will help your RA. Sending you positive thoughts. Jenn
