Reply To: Hizentra side effect

I had this happen to me a few years ago on Hizentra, was so strange, as it had never done that before. It probably happened a total of 8 infusions in a row (two months), and then never happened again. I’ve been on SCIG for over 5 years, and those were the only 2 months it happened just like your describing. I honestly was worried I was getting cellulitis/skin infections, but it would always resolve without intervention after a few days. The only thing I could thing of is if it was something about that batch – contamination/different antibodies that caused me to react.. not sure… so I’ve chalked it up to every batch is different.. I hope it improves for you!
