Entocort does the trick for my daughter...am sorry it didn't work for you.
While checking out other med options, you might want to try a safe natural remedy, like eating yogurt. We make our own, fermented 24 hours. This makes the yogurt far stronger than what you might find in a store and within 24 hours, bacteria have eaten all the lactose in the yogurt. That said, even commercial yogurt might help. Also lots of fruits plus vegies (but vegies cooked very well, and fruits peeled, keeping in mind your stricture)
