Hi, my guess is that the ammonia smell is because of the protein load that is present in IV IgG. When protein is broken down, it makes ammonia and the body trys to regulate the amount of protein in the blood. this means that if there is a lot of extra protein, it will be broken down.
I also have gotten night sweats with IV IgG infusions. I thought it was associated with cytokines released in response to the IV IgG, but do not know this for sure. It just makes a little sense with the “flu-like” feeling that comes with the infusion.
