IVIG is not a cure for mg. It is simply a way to support your body so the mg affects you less and it does wear off over time. The most common way IVIG is given is monthly with a dosage of 2 gm/kg of weight monthly (spread over 5 days). However, if this doesn't work for you, you can change up the dosage and timing. I have been on IVIG for about 10 years and am currently doing .50 gm/kg of weight weekly. I work with my neuro to do what's best for me and I think I've had every combination possible over the 10 years.

IVIG doesn't work for some individuals, but I believe the majority of us who do use it, use it help manage our mg and I can't imagine what my life would have been like without it.

Hope you find what works for you and you get your mg under some sort of control.
