Reply To: CIDP big relapse vs mini relapse?

I think the use of IvIg for GBS and CIDP is “off label,” but it is nevertheless generally accepted

At least for CIDP, I think IG is FDA approved, at least for some brands. As for insurance, you can appeal denial, but search their medical policies online for IG and CIDP. It was listed as allowable treatment in mine.
