Yes - my son has received IVIG numerous times and had the severe side effects often. He doesn't use IVIG anymore (we switched him to WinRho a few years ago) but a couple things may help you if you have to get it again:
1. slow infusion. You mentioned this, but don't let them speed it up the second day. You should call/email your doctor to document your reaction, so that you'll be on record and they will stay with the slower infusion rate the next time.
2. stay hydrated. Brady would drink as much as possible at home and then would receive saline before, during and for a couple of hours after the infusion. It adds time to the process, but seemed to help. When you get home, keep drinking - even popsicles help.
3. pretreat with Tylenol, Benadryl and a steroid - they always gave Brady Solumedrol. Then, it helps to continue with the Tylenol and Benadryl throughout the treatment and for 24 hours after you get home. Brady also received Zofran (an anti-nausea drug) sometimes and we would have a prescription on hand once he was home.
4. talk to your doctor about the brand of IVIG. Late in the game, we discovered through this forum that the brand of IVIG can have an effect on your reaction/side effects. Different brands affect people various ways, but it may be worth it to get something different next time.
I hope you feel better soon! Brady would usually get the reaction about 24 hours after the infusion ended and then he would feel better 18-24 hours after than. THen, he would need to rest for a day or so - it really wiped him out. Although I never personally experienced IVIG, Brady's suffering looked unbearable at times so I feel for you. The good news is that IVIG always bumped Brady's counts up in to the 300s, so I hope you get the same great response from it!
