Why up the dose?

I guess I didn’t quite understand your question, has the current dosage of IVIG quit working? Because Brandy is right, IVIG is based on weight, giving more will not make things better. Is that why that want to try other immunosupressants? If possible I would try to avoid using any of these on one so young, there will be frequent blood tests & worrying about possible liver damage. Also, try to stay away from steroids on one so young. But again, I don’t know is current condition or how the IVIG is working…
