Well it is a steroid, and its supposed to have less systemic side effects. But I wouldn't be surprised if the Entocort was given you the moodiness. I am on Pred, just started it, and so far I haven't noticed anything other than increased appetite. Some folks get little to no side effects on Entocort and others do have some side effects. Hope that helps.
