HI,
I never got a rash but did get severe flu symptoms that are the typical, side effects, the first time I had IVIG. I have MMN. After 2 years of differential DX of
ALS or MMN. Doc is sure it is MMN. My premeds do exist of benedryl and predisone (IV form -solumendral) and tylenol. In addition for the prevention of headache which I had for a week after the first treatment (and I have had maybe 8 headaches in 60 years except during my second preganacy), I get prescription composine.
All the extra meds come with my IVIG treatment, which I get at home, except for the compozine which I have a prescription for and get about one script per year as I only take it prior to treatments every 3 weeks. These meds take care of the side effects completely. I am a little red faced the day after, which for me is tomorrow, and I am a little hyper from the steroid, which is of course a nice change. Sorry for too much information, and now that I said that, I am sure it is the prednisone talking.
Best Wishes, Peg
