Last month I was diagnosed with PACNS, or Primary CNS Vasculitis. I've been taking daily prednisone and the plan was for monthly infusions of Cytoxan. When I visited my rheumatologist this month, he recommended switching to daily Azathioprine instead of the Cytoxan. I've only had one infusion of the Cytoxan so far and didn't have any major side effects. From what I've heard, Cytoxan is the most popular treatment plan.
Has anybody tried Azathioprine? What were your experiences with it?
