Im sure you have read this all already but in case you havent. There is a possibility of allergic reactions to the IVIG, so I believe they give you benadryl before they administer it. Infusion rate is also important to avoid side effects. Nurses have a tendancy to want to get finished and I have read posts where the infusion rate was speeded up to the detriment of the patient. There is poster in www.neuropathy.org named Eugene who has a lot of experience and information about the side affects and infusion rate for IVIG. I think he has had CIDPsince 1968!. From your previous posts it sounds like Alan is in pain but is able to go to the gym and live a relatively normal life. Ivig isnt a cure , its a 30 day treatment which helps alleviate the symptoms of CIDP or other autoimmune conditions. If it were me Id think long and hard about trading off 4-8 days a month of infusions and side effects if my CIDP werent a major threat or impediment in my life. If it got worse of course I would try it, but I would wait until then . Ive been offered it but it seemed to me to be swatting a fly with a shotgun approach. In the meantime I would try various things to alleviate the pain. I know im bucking the tide of the postings in this thread but I felt the need to add my 2 cents for what its worth.
