Minimum yet effect dosage of IVIG

hi all,

I recently finished my first set of 12 doses of IVIG. I was receiving 1 mg/kg of body weight. While it seems to have halted the de mylenation progress there are are lot of side effects, namely the feeling like you have the flu.

my clinician just changed the prescribed dosage to .4mg/kg of body weight.

while this should help with the side effects, i don't want to find out that it was not enough, and that i have lost more nerve.

Has there been a consensus reached of what the minimum yet still effective mg/kg of body weight the dose should be?

any feedback would be greatly appreciated
