I have been on 6MP for about 7 years now. I too was worried about the infection part. I have been blessed to not have had a problem with infections. Suprisingly I have been way better with the 6MP than before I was taking it. I too work with kids both at work and at church so it was a concern. I try the best I can to stay away from sick people, but I cannot tell any more infections have come my way since taking the 6MP.
I take 75mg a day. At first I had my bloodwork done weekly for about a month, then I went to monthly for a few months, now I have it done every three months. My doc will not refill my RX without my bloodwork being done.
6MP was by far the best drug for me. Remiciade did not work for me and 6MP got me to remission. Good Luck!
