Yes, I've been on it. This is my second time. Apparently, it was first used successfully with IBDs, then they did some successful trials with Microscopic Colitis (collagenous/lymphocytic C.). I've not seen any info about it with IBS, but I don't see why it shouldn't be tried if you're unresponsive to OTC and Prescription meds. Being a corticosteroid there are risks, its low, but real. Its still much, much safer than Predisone. [Edit: I should add that ideally, they use a course(s) of Entocort in the hopes of achieving a remission that 'sticks' after withdrawal. Hence the pulse treatment approach.]I've had Dx'ed microscopic colitis for nearly 11 years now. Bloating/gas, nausea, abdominal pains, big time D.Just tried Entocort for the first time in late 2009. The GI prescribed a tapering 4 month course, which I stretched to 6 months. Within 24 hours of starting the drug I saw/felt results. I felt great while on it, even at the minimum 3mg dose 1x a day. Sadly, within a few weeks of ceasing treatment all my symptoms came back. No worse than before, but its very frustrating.Now I'm seeing (yet again) a new GI. He put me back on Entocort starting at 9mg 1x a day. He has said that he'd like to find the minimum effective dose and keep me on it long term, like a maintenance drug, instead of the pulse treatment that its commonly used as. I've read that some folks have been on a continuous low dose for years, yes, years, with no ill effects.The only side effects I ever experienced were a slight facial flush after dosing, and some 'steroid mania', both of which subsided within the first two weeks. I would advise you to take them first thing in the morning, or whenever you start your day. Otherwise they can effect your getting to sleep.My experience with Entocort is here, if you're curious. Some great info links are posted by Kathleen and Elizabeth, some studies I found about Entocort, and a link to a site I found that focuses on MC. They had/have some good info/experience with Entocort and were a bit of an inspiration for me to push this GI to consider long term dosing.
