I'm on Pentasa and have been for 6 months now. No side effects that I have noticed other than spotting a feww of the white mini capsules at the other end....
I like you went on at the same time as I was on steroids for a flare, however i got no nausea.
Not sure if that helps

p.s. I still feel new and full of questions and I 've been here for over a year now (not v active though!) Tend to really abuse the site when I'm sick and then ignore the site and the disease when i feel better. I'm a user - sorry!
