No, she didn't taper too fast. She followed a slow taper schedule:
first, 4 weeks at 9 mg daily
then, 3 weeks at 6 mg daily
then, 4 weeks at 3 mg daily
then, 3 mg every other day (one day on, one day off Entocort)
When she got down to the every other day schedule, she went into full flare on the third of the "off" days and landed in the ER.
That was in July 2006 and the good news is that is the last time she flared. We weren't taking any chances, so she stayed on Entocort for years.
What scared us most was that when she went back on the Entocort, it took longer for it to work for her. This meant that if she went off it again, and then tried to go back on, it might now work at all.
So she stayed on Entocort for years, most of the time, on just one pill...combined with diet changes.
