What I though was a flare up before remicade, was a side effect from Asacol. My daughter was having pain and loose stools about 10 days before her remicade dose. Called the GI and he told me to stop Asacol and see what happens. One day with out it, loose stools gone. Pain started to decrease and after 4 days gone completely. She did have her Remicade today. Everything went good. Some blood test came abnormal, Need to talk to Doctor tomorrow.
