Hyoscyamine for Irritable Bowel Syndrome "Unfortunately, I had horrible side effects from Levsin, and it only seemed to make my symptoms worse, caused me to feel nauseous, vomit bile, have diarrhea several times a day for several days on end (not sure if it was bloody or not, but I don’t recall eating anything red in color). It gave me severe dry mouth and made me burning hot. Wouldn’t wish that experience on my worst enemy."

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 "This was the worst drug for me. I ended up using it for a little over four years, thinking it was helping me and my severe IBS, but in reality, it was just slowing my GI tract down to a crawl. So much so, that my IBS worsened. I became reliant on suppositories and enemas to have a BM. The constipation, caused by hyoscyamine, caused bloating, nausea, and GERD, which had me taking more hyoscyamine, which just further worsened the issue. It was like a horrific death cycle I wasn’t able to break free of because I didn’t know the hyoscyamine was causing the problems. I lost so much weight and became so insanely sick. Unfortunately, trying to get off this drug was also awful. My GI system had become so reliant on it that it didn’t seem to know how to digest and work by itself. Still, I quit cold turkey, and after 3 or so months, I was thankfully able to get my body back to a reasonable place so I could find an IBS treatment that actually works. Stay away from this drug."
