For Irritable Bowel Syndrome "In 2000, I was initially diagnosed with ulcerative colitis. I was on one drug for 18 years and had three colonoscopies with three different GIs. About four years ago, I began vomiting and having diarrhea a lot during the summer. One year, it was about every other week. Just this past year, I began experiencing severe constipation too. I thought my UC was getting worse, or that I was not tolerating the heat well. Another symptom was profuse sweating. My new GI looked at my scope results and the recent history and determined that I was misdiagnosed. Instead of UC, it should have been IBS. He said the vomiting and sweating were related to the vagus nerve. I quit the UC drug and began hyoscyamine sublingual. So far, I have had good results. I am sometimes not sure if I should take it at the slightest hint of a stomach cramp, but I’m not taking chances. I go for a follow-up soon to see if the doctor’s new diagnosis is correct."

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 "This medication works for me for a few hours, most of the time, when I get in a bind and have to leave the house, but I experience a wicked backlash of increased diarrhea for days after the one dose wears off."

For Irritable Bowel Syndrome "I originally was prescribed this for a 'nervous stomach' due to diarrhea from severe anxiety. It works to control my bowels and stop the cramps. I have been on and off the meds for about 10 years, using it to help with flares - it is now known I have IBS. If I take it more than 3 days - 3 times a day as prescribed, I have severe constipation. I use it as needed, taking a single dose every day, and more if I have a flare, stopping for a few days only if I have harder stools."

For Irritable Bowel Syndrome "Made my diarrhea even worse. If it contains sulfa I’m allergic to, why would my GI doctor prescribe it?"
