For Irritable Bowel Syndrome "I have long-time IBS with two diverticulitis attacks within the last 4 months. This medication does quell my pain (10mg) within one hour of taking it. For this, I would rate it at 10, however, the side effects are very bad. Double blurry vision, extreme dizziness, lethargy, and disorientation. Do not make any plans outside your home if you plan on taking this. I only use it when the pain and discomfort becomes extreme. So thankful my wife is a former EMT-I and a CRNA. She helps me much."

For Irritable Bowel Syndrome "I have a stomach bug (gastroenteritis) that has lasted 3 days so far. I was prescribed Bentyl and Zofran on day 2. I do not take pills well, I'm always worried about side effects. I decided to take one after being prescribed Bentyl anyways. I am a 28-year-old female weighing about 175. Bentyl made me a bit dizzy for about 2 hours, but not too bad. Make sure you take it with a full glass of water and lay down. Day 3, I took another pill, thinking I'll be fine with just a little dizziness. I was wrong. I did wait too long between doses, I'm not sure if that's what caused bad side effects (18 hours in between) or because I can't handle muscle relaxers. Either way, exactly 30 minutes after taking Bentyl this time, I was slowly becoming 'high' but not in a fun way. I sat down, had some soup, and as soon as I stood up to walk, I felt really low to the ground like gravity was pulling on me pretty hard. I was very nervous from this point onward until it wore off by the 2nd hour."

For Irritable Bowel Syndrome "After starting Bentyl, I had severe vertigo and had to figure out myself it was Bentyl (I am a nurse). Please take this medicine only if you make yourself aware of the side effects, especially any major change in physical condition. I also have GERD, which I found out is contraindicated."

For Irritable Bowel Syndrome "I've been on Bentyl for a little over a month now. At first, it was great, helped with the painful attacks I was having. Now I'm so dizzy from it that I can't function, even as a stay-at-home mom. I can't drive to my doctor's appointment, and all I do is sit at home in a daze."

For Irritable Bowel Syndrome "I take Bentyl for irritable bowel syndrome flare-ups, and it does work for me. I would suggest taking it at night before bed or make sure you're home because it can cause drowsiness, dizziness, and dry mouth. This is an antispasmodic, also known as a muscle relaxer. So be careful when taking this. It really does work wonders."

For Irritable Bowel Syndrome "First, I want to thank you all for your reviews. These reviews helped me to finally be brave enough to take Bentyl for IBS. I was sick for months: constipation, bloating, sudden diarrhea with syncope sometimes, lost 35 lbs. without trying, and highly sensitive to various foods. I logged everything I ate, drank, and every BM for 5 months. I was tested for everything under the sun... multiple blood labs good, multiple stool labs good, good upper & lower GIs, CT scan. I had nothing physically wrong with me to be found. My primary care recommended I try Bentyl. I avoided it due to some of the horror stories I initially read online about possible side effects. Months later, I finally tried it after reading some of your reviews on this website. For the first 2-3 days, I had some minor dizziness and felt tired. But after sticking with it for a few days, those side effects went away completely, and I feel absolutely normal. I only wish I'd had tried Bentyl sooner."

For Irritable Bowel Syndrome "This worked like magic on my horrible, knife-like abdominal cramps and bloating. Within 30 minutes, my tummy felt great! But... Bentyl leaves me unable to work and barely functional. When I would take it, it would make me so confused I couldn't remember where I was, why I was there, or what I had just been doing. I would stop talking to someone mid-sentence and not remember what we were talking about or how I got there. I often couldn't answer simple questions. I also became very dizzy. I would only take it again if the IBS symptoms occurred at home and at bedtime. Such a shame. Nothing took away my pain like Bentyl did."

For Irritable Bowel Syndrome "I went back to this due to side effects with another medication. Bentyl is cheap and works, but the side effects make me dizzy and tired. I'll keep taking it because it's the only thing that works. Must take 2-4 times a day to not have cramping, but definitely works for cramping like nothing else."

For Irritable Bowel Syndrome "Within 20 minutes of taking Bentyl 10 mg, I had blurry vision, dizziness, and depression with suicidal thoughts. Reduced my abdominal pain by about 80%, but the side effects were unbearable."
