I normally get 5 treatments over 3 weeks but I just had some kind of infection (minor) and I have switched from Imuran to Cellcept and Prednisone. The infection knocked me on my butt (very weak) so my Dr just scheduled me 2 IVIG treatments a week for 4 weeks (8 infusions). My last IVIG was in Nov. It appears to me I need IVIG about every 6-8 weeks but my Dr hasn't said that.
