Hi Mike - I do IVIG every 2 weeks, but part of the issue with IVIG is the dosage. The normal dose of .4 grams/kilogram of your weight. I used to get it monthly for 5 days. I now get 1 gm/kg and do it bi-weekly. This give me a larger dose all at once without increasing the overall IVIG. It seems to work better for me. I've been doing this for about 6 months.

Good luck in finding what works the best for you.
