question: I was diagnosed with Wegeners disease 2 weeks ago after being in remission for about 4 months. They just startedme on Cytoxan which I am to start tomorrow, and  My doctorhas prescribed intravenous Rituxan to be started next week. I am allergic to prednisone. Is there a different med to take in its place? I read all the side effects for Vatican and Rituxan.  Also, what are granulomas?? Should I be havinga second opinion as far as these drugs that have been prescribed.  I am 59 years old and the anca is 1_640.Thank you
