I haven't had it done in over 17 years but when I did I was inpatient for a week, but then that was long ago. My Dr. wanted it done again now but the hospital that does it in my area is concerned because of infection in the shunt area {I don't have a shunt} but the Dr. is afraid to give me one. Sadly I think I am going to have to go for it because I can't take any medications so plasma exchange is my only option, at least I know it works
