Severe IBS and Crohn's Disease...how to tell the difference?

Hi Bobafett, Welcome to the IBS board!  I feel for you... I can't imagine having IBS and IBD.  There are, however, a couple members on this board that do have both.  Hopefully they'll be around to share some tips. Sadly, there aren't too many meds out there specifically for IBS.  The main ones seem to be antispasmodics and even anti-depressants/anti-anxiety meds.  Others are more basic like fiber and probiotics.  Here is a list I had posted in a separate thread: Antispasmodics - Levsin, Bentyl, Donnatal, Pamine, etc. Antidiarrheals - Immodium, Lomotil, Calcium Fiber supplements - Psyllium, Metamucil, Citrucel, etc. Laxatives - Miralax Anti-Depressants - Elavil, Paxil, Prozac, Effexor, Zoloft Anti-Bile - Questran, Welchol For constipation there is Tegaserod (Zelnorm) that is supposed to keep the bowels functioning properly and regularly.  It treats constipation, bloating, and abdominal discomfort. -- THIS MED HAS JUST BEEN PULLED BY THE FDA For diarrhea there is Lotonex.  It reduces cramping, discomfort and urgency. Probiotics - Promotes a healthy gut flora... it is "good bacteria" that helps push out the bad. Digestive Advantage is for all IBS symptoms: bloating, diarrhea, constipation, abdominal discomfort
