There are different brands,was your rate too fast? Hope you are feeling better. I reacted badly to two of the brands and the dip nurse ran it too fast. I developed severe rashes, sick as a dog etc. The third brand, I did not react to. Less preservatives etc. and my doc said it was better. I will post the one I tolerated tomorrow, Not saying you can use it but just fyi.
It was Gamunex.
ps did they check your blood work for IGA also?
