Rate does matter. The slower the rate, the less luckily you will have a reaction. I had a very bad reaction the first time. They now do my rate at about 5 hours and I switched from gammagard to gammunex and have no reaction. I also do not take the benadryl, I do better without it.


I would ask them to slow it down and also consider a different product. Gammunex seems to have less reaction (more expensive) than gammagard.

good luck
