Hallo I'm new to this group. I was detected with Crohns three years back. Today I started Humira . Can say still very apprehensive as I live in South Africa and TB is a real problem.. I cannot take the anti viral drugs to protect me cause I have bad allergy to them. So I have choosen To go ahead with Humira and take the risk..... Any one out there in the same situation and if so what precautions do you take?
