Report Combination IVIG/Mycophenolate ( Cellcept ) treatment anyone ? ? in Dysautonomia Discussion Posted September 5, 2017 So happy to hear of your improvements but sorry the last medication did not seem to help. I have a friend that is using IVIG and Rituxan combination. She has been on this combination for awhile. However, she also does a plasma exchange treatment every 3 months to keep lowering the autoimmune antibodies. Eventually, the goal is to stop doing the plasma exchange. Don't know if this combination would be a possibility for you but thought I should mention it.
