Different Brands of Immunoglobulin

Has any one else had the experience of a better outcome with a different brand of Immunoglobulin? My son had a better outcome with flabegamma when he changed from Provigen. ? Thanks. Brenda


I had that same thing happen to me. I do best on gammunex I had bivigam (?) and it didn’t seem to work as well. There’s another one that works good for me too but I can’t remember the name it was too long ago. The nurse told me it may have something to do with the glucose that is or is not present in the IVIg. Apparently there are different amounts of this in each manufacturers IVIg. Some people can’t have the glucose so they do better without. I’m not a doctor so you may want to ask the Neuro about that to see what they think.
