Reply To: 40 days and no response to ivig – can it still work?

It may be that your doc needs to increase your dosage. Your story sounds a lot like mine years back. I was on 450 ml. every 4 weeks. No improvement. I was nearly crippled. Then my doc doubled the dosage to 900 ml every 3 weeks. Now I’m back on feet and back to work after being out on disability for over year.
