I am not pregnant or on Pentasa, but do take the sister med Asacol. These are the mildest meds to treat Crohns. Many women on this board have had babies while on Remicade and Imuran. And all their babies have been completely healthy. Stef17 is one who comes to mind. In my humble opinion, if they can have healthy babies on immunesuppresants like that, I am sure Pentasa would be completely harmless to the baby. Good luck and I am sure others will be along soon to share their stories.
