Hyoscyamine for Irritable Bowel Syndrome "A gastroenterologist prescribed this for me when I was having very severe abdominal pain from Sphincter of Oddi Dysfunction and IBS. Well, it did everything but relieve the pain. It blurred my vision, made me nauseous, gave me a pounding headache, made me feel very hot, dried my mouth, made me drowsy, and slowed down my heart rate. The pain continued to worsen, and I ended up in the ER. I had several more attacks afterward, and the Levsin didn't work then, either. I was then referred to another gastroenterologist, who prescribed me Bentyl and Doxepin. While I have had fewer side effects with them, they haven't touched my pain, either."

For Irritable Bowel Syndrome "Before I began taking this medication, I had gotten to the point where I couldn't eat anything without getting sick, and just the thought of driving more than 10 minutes, or even taking a route without a convenient bathroom stop, caused debilitating anxiety (which made symptoms worse!). Since taking it, I can travel and eat normally again. Dairy and alcohol still upset my stomach, but other than that, I am living a normal life. Some days I still get sick, usually around my 'cycle,' but the improvements from before the medication are astronomical. Especially since side effects have been minimal-only major one is headaches if I don't keep my fluid intake up."

For Irritable Bowel Syndrome "I'm 18, female. I seem to have drawn the short straw with this medicine. I'm very lightheaded, sensitive to light, and lethargic. On top of that, I've had headaches and dry mouth, and I've lost my appetite. I suppose my symptoms have improved, but things are only better in the hours after taking the pill. Since I didn't have severe irritable bowel syndrome, just cramping and frequent trips to the bathroom, the side effects negate the benefits. I cannot function as well as I would like. My lightheadedness has kept me from moving around much. I'll definitely be asking to have my dose lowered or the medication stopped, because I'd rather be in some pain than be on the verge of passing out whenever I stand."
