Thanks for the info! I am getting maint. doses. I was getting them every 4 wks an now every 3. I have never been on prednisone not for gbs. I do pre-meds of tylenol & Benadrly. Even with the pre-meds I will still get headache/nausea. They also give me zofran prior to infusion and infuse over 6 hrs. When I receive 5 days if ivig I get deathly ill weith meningitis symptoms, high fever, BAD BAD headace and N/V.
