I recently was diagnosed with MG. After crisis intial tx was Prednisone 60MG daily for 3 weeks. I literally had a psychotic break, no sleep, no filter on things I said to people was readmitted to MGH and spent week in Psych unit detoxing from Prednisone. This is a nasty drug and needs to be carefully monitored. I have been treated with MEstonin and two sets of infusions and for the last month my symptoms have been negliglible. I developeda severe rash all over my body a week ago and it tis itchy and very uncomfortable. So I am on a medication holiday. Stopped the Mestonin. However the heavy head and extreme fatigue symptoms hve sarted to re occur. I have also found that CellSept is not paid for by my Medicare/United Healthcare Supplemental insurance and that there is a generic. Has anyone had experience wih generic or suffered a horrible rash as a hangover from the prednisone?
