My doctor put me on Robinul (as needed) along with a proton-pump inhibitor and Carafate (sp?) for gastritis. That fixed some of the symptoms but the cramping, bloating, and gas continued so after a negative CT he is calling it IBS episode. He gave me a new probiotic and told me to take the Robinul every 3-4 hours (ie. by the clock, not by the symptom). I'm hoping the improvement is from the reduction in stress (from clean CT) and the probiotic, because the Robinul gives me really bad dry mouth and dry skin. And oddly enough I think it's contributing to the constipation that is categorizing this IBS episode (I'm usually more IBS-D)If my symptoms continue to stabilize, I'm going to ask if I can cut out the Robinul. But was wondering about other folks experience with this drug? Is there another drug in the same category that doesn't create dry mouth?
