The brand seemed to make a difference for me.. i want to say I was on Cariummune or something like that initially.. had the rash, meningitis etc.. we swtiched to Gammunex (they say it's a "cleaner" IVIG), and people tend to have less reaction to it.... sometimes insurance makes you "fail" other brands of IVIG before approving Gammunex, as it is more expensive than a lot of other brands..

How are you doing?
