Hi has anyone experienced an allergic reaction to Gammunex c? I had a pretty bad reaction at my last infusion hives, heart rate went up to 135 BP went up to 145 over 83 which is high for me (norm is around 98 over 70) i found out later that the pharmacy said it was a "Bad lot number " and therefore they were throwing out that batch. Uuuggg. Im still experiencing palpitations 5 days later. Has anyone had Gammunex c? I looked up their website and it looks like they've had this problem
