For Irritable Bowel Syndrome "I honestly thought everyone’s stomach was uncomfortable after eating. It wasn’t until I started taking this drug twice daily that I had that revelation. My IBS was getting to the point where I had crippling stomach pain 1-2 days out of every week. I started taking it as needed, but there was little relief that way. My doctor told me to try taking it daily, and it’s wonderful! No bloating and gas after meals (or in between), and I no longer look like I’m 4 months pregnant all the time. If I start feeling a little upset stomach, I can take 1-2 more each day, and that does the trick. I only feel mild tiredness, which is going away as I take the medication longer. I am so excited about the doors opening for me with the pain being put to rest!!"

For Irritable Bowel Syndrome "I have had IBS for about 18 years. Symptoms of bloating, swollen stomach, looking like I'm 6 months pregnant, severe cramps, very loose bowels. Symptoms lasting weeks, making me home bound and in bed. Eating crackers and drinking juice. I have gone to a number of doctors. Finally, my gastroenterologist prescribed Bentyl. I was taking it 3 times daily, then 2 times daily. Because it made me tired, I now only take it when I have flare-ups. I try to take it at night when possible. This medicine has really helped me. I highly suggest it."

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 "Diagnosed with Irritable Bowel Syndrome, was going to the bathroom 10x times a day. Was prescribed this two weeks ago. Take 3x times a day. So far pill works great down to 2x times a day and my stomach looks smaller since I was always bloated. Only side effect I've noticed is it makes me tired during the day."

For Irritable Bowel Syndrome "I had an infection called Clostridium difficile in 2014. Ever since then, my IBS has been worse than ever. This drug is a lifesaver for me. It works within minutes to help calm down the stomach pains. It helps immensely with gas pains. I love this drug. I have been on it since 2016, I had to have a stool transplant, and I had the worst stomach pains ever after that for months. I take it as needed, but lately, I have had to take it more often due to an increase in IBS symptoms again. It does make me tired and causes dry mouth, but other than that, there are no side effects."

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 "I have had stomach issues since I was a kid. I was recently prescribed Bentyl up to 4 times a day. It works great, calms my stomach and digestive system down like nothing else I have tried over the counter in the stores has. It can make me a little fuzzy-headed or tired on occasion, but it doesn't happen every time. I will take that small side effect over my stomach problems any day. I highly recommend it."

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 "After being diagnosed with irritable bowel syndrome with constipation, I was started on Bentyl 20 mg up to 4 times a day. At first, I was not happy with the tiredness, so I only took it twice daily, but now I take it 3-4 times a day as needed. Although it doesn't eliminate all of the cramping and gas pains, it does make a huge difference."

For Irritable Bowel Syndrome "This medication works wonders for me. Tend to get stomach cramps regularly, I miss work sometimes because I am constantly running to the bathroom. If I am traveling, I have to stop and use public restrooms. I never know when it's going to hit me. I am weak and faint sometimes from these flares. The only drawback is that it makes me feel tired and I get blurry vision. It has really helped me."

For Irritable Bowel Syndrome "I've been suffering for two weeks before I got prescribed Bentyl. Bentyl has helped greatly and helped with the urgency I was feeling. I don't like the drowsy feeling it leaves, but I suppose I'd rather have the tiredness than the constant problem of 'going'. Bentyl has been a good medicine for me. I recommend it to others who suffer from irritable bowel syndrome or other problems!"

For Irritable Bowel Syndrome "Double-edged sword for me. I take it for Crohn's disease. If I start cramping up and take Bentyl, it does typically help with bowel spasms fairly well. On the flip side of that, it tends to make me a bit drowsy and kind of lethargic, and occasionally causes panic attacks and anxiety that last for a few hours. Kinda have to weigh the risks with rewards though."

For Irritable Bowel Syndrome "I was prescribed this after gastric sleeve surgery for stomach cramps that I was told would happen. It's been a lifesaver. The first month I took it religiously as prescribed because the pain was the worst. Now I take it as needed (per my Dr), and it helps so much even with an upset stomach. It does make me a little tired but not enough to make me want to go to sleep for hours. I keep it with me at all times in case my stomach acts up."
