Panzyga

Has anyone taken Panzyga? How long did you take it for? All the literature says six months and nothing is mentioned about after six months. Has anyone had a reaction to it? I an excited about starting it yet at the same time leery since I have over 50 drug allergies. I imagine when I took it as a child there were not so many options. Everything I have read up on IVIG therapy says once you start it your on it for life but what I can gather from this you only take it six months. Which does not make much sense since it does not stay in your body very long. You look at the charts and it barely stays in your system for a month. I have done a lot of continuing education credits on this for my RN degree even though I can no longer work. I have left drop foot but now my whole left leg is dragging having a hard time lifting it. It does not want to work.
