Dosage is figured by weight. It's usually 5 mg. per kg. (2.2 pounds) of body weight, but can increase to 10 mg./kg. if needed. I'm on 5 every 8 weeks, myself.
Moderate to severe left-sided UC diagnosed 2001.
Current meds are Colazal, Azathioprine and Remicade. Completely off steroids for more than a year now! In remission since April, 2006. Remicade has been my wonder drug.
Now tapering Azathioprine, please pray for me.
