From what I've read online a typical IVIG regime is 5 initial treatments followed by single treatments every 4-6 weeks. The infusion itself takes about 2 hours. My neuro, however, requires that I have a urinalysis and blood work to assess renal function with results obtained prior to each infusion. I'm usually at the infusion center for about 4 hours. I know that some people actually do their infusions at home, but my neuro prefers that they be done at the hospital.
