Hello Doug,
I also have MMN, I was 65 years old (Female), when I was diagnosed. Now I'm 69 years old. The IVIG did not work for me. I got mennengitus 2x from that drug. This was back in 2010.
On Feb. 2011 my Neurologist put me on Hizentra, per infusions, done at home. 3 grams (15 ml) twice a day, twice a week. Over time that has increased to 4 grams, (20 ml ) twice a day, 4 times a week. The drug is expensive, but I do have Medicare and Humana supplement insurance, with a co-pay of $860.00 per month. However, I'm doing very well on this drug, so far.
Sincerely,
Maria W
