yeah, that doseage does seem high. clinical trials showed that there was no benefit in upping the dose beyond 9 mg, which is why the manufacturer's instructions list that as the highest dose that should be taken.
entocort worked great for my daughter...in remission nearly two years. nearly one year, at only 3 mg daily. she has a stricture, too, but it is a problem only when she flares, which happened only when she tried to go off entocort.
