Hello,
I am on IVIG and initially the Dr wanted me to be on a brand that I would do at home however my insurance which was private insurance then approved another instead which I go to an infusion center once a month for, not sure why. I am now on Medicare with a secondary and paid around 250.00 for my deductible the beginning of the year. I have paid nothing else each infusion. I think the first thing is what your provider would like you on then finding what brands are on your insurance formulary. Good luck and I hope you get the help you need.
