Thank you for your reply.
Sorry to hear you had a terrible reaction to IVIG. I had minor cough and itchiness the first few minutes into the infusion but they stopped the treatment and gave me max dose of Benadryl. Waited about an hour and then they restarted the IV at a much slower rate that worked and was able to finish the full dose but just took longer.
You may be very allergic to these types of infusion medications. I hope you are feeling better too!
