I started out having only mild reactions a little headache, fever, rash. But on my second year of IVIG I started becoming very sick afterwards. Now I take it in 3 days at 120mg. rate, the pediatric rate! I’m not sick anymore so who cares! I would do it even if it did make me sick. It helps that much.
I have a tendency toward low iron, so phenergin doesn’t work for me, I get terrible reaction to it when my iron is low.
Be blessed, you are not alone.:p
