Hi, I was on Entocort for quite awhile but I never experienced a side effect like that - pretty much the opposite for me, when I tried to taper but my body wasn't ready for it, the diarrhea came right back for me. Do you tend to have constipation rather than diarrhea? I would mention it to your doctor and see what they have to say. Is the constipation painful? Are you getting other symptoms like cramping or nausea?
