What made you decide not to take the sulphasalazine?
Supposedly some of the various arthritis types are diagnosed by the way your bone degenerates - which means it can be seen in an x-ray. I also psoriatic arthritis, but my doc now just calls it RA. He wasn't w/me the years of flares that were beyond feet and joint pain that all pointed to P.A. Doc now says, "it doesn't matter specifically which you have, you'll be treated/medicated the same either way."
I have never taken Imuran, but it seems there are few people here who do.
Good luck. It sounds like your body is on a rampage.....have they done a full panel of blood work to make sure your body isn't fighting something else causing such massive inflammation right now?
D-Rule, I know you are hoping for someone to answer who actually is ON the medicine, but I found this on the web...you probably know this already, but I wonder, do they use RA as a general term for various forms of it?
I found this at: http://www.netdoctor.co.uk/medicines/100001329.html
"Imuran tablets and injection contain the active ingredient azathioprine, which is a type of medicine called an immunosuppressant. (NB. Azathioprine tablets are also available without a brand name, ie as the generic medicine.) Azathioprine is used to dampen down the activity of cells in the immune system...."
"...This can result in various disorders known as autoimmune diseases. For example, in rheumatoid arthritis the immune system attacks the joints, causing pain and inflammation. In systemic lupus erythematosus the immune system attacks the skin and internal organs. The activity of the immune system can also be a problem following organ transplants, because it recognises the transplanted tissue as foreign and attacks it, causing the organ to be rejected. In situations such as these it is useful to suppress the activity of the immune system...."
