I did 84 PlasmaPheresies on a weekly basis but had to get off because of me getting anemic my Iron and RBC were getting extremely low...so now I've been on IVIg for a little over a year every 3 weeks 80g infusions and doing ok, it's not as good as my PlasmaPheresies but keeping me a float and really helped me fight off viruses and infections, my Iron levels are back up and my RBC are 160, when I was on PlasmaPheresies I got shingles!!! real bad because of my system being out of balance. I'm also on a heavy dose of Mestinon and 200 mg of Imuran/Azathioprine daily plus 10ui VitD daily and maintaining a descent lifestyle.
