For Irritable Bowel Syndrome "I am a very tiny 104 lb 21-year-old who's been suffering from IBS-D post-cholecystectomy. Now it's been a year since I deal with trapped wind, intestinal pain & bloating, diarrhea. It is literally my ileum & descending colon that I feel spasming horrendously, I can only imagine it feels like labor. I have a love-hate relationship with Bentyl. I'm an emergency Bentyl user (read the potential long-term use effects). This helps at least 90% of the time. And when it kicks in, I think, 'that attack wasn't that bad'. It stops the spasming and it decreases the pain, score 10, pain during drops to a 2 60ish minutes later. 8/10 because of side effects. Mine include blurry vision and confusion. I had to leave work one time because I was just confused, had blurred vision, and was having an anxiety attack. Believe me. Stay at home for the few hours or take it at night. I honestly hope I helped someone because IBS sufferers need to support each other."

For Irritable Bowel Syndrome "I was 18 when I took Bentyl, had stomach problems on and off for about a year and a half, it was so bad one day that I couldn't get out of bed. About 5 months after that, I was prescribed this medicine. It did NOT help at all. While I understand that it can be a hit or miss for most people, I have to say that the side effects made my pain seem like nothing, and that's not an exaggeration. I took my first dose in the evening (10mg), and within a half hour to 45 minutes, my left arm and lower neck went completely numb, my hands were tingly, my vision became blurred, I had trouble breathing, I felt cold, and I couldn't concentrate on anything. I even took the medicine and was safe about it, did everything my doctor told me to do, but it made no difference. I genuinely believe this drug isn't worth the side effects, especially if you already suffer from mental problems like I do."

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 "Started with a low dose at 10 mg to avoid drowsiness. This was the only option for me after fighting IBS for over 15 years. Works on your first day right away. The only side effect is a little blurry vision. I take one dose right before dinner time. The pill regulates the bowel movements like clockwork. This pill also helped me with my sleep issues."

For Irritable Bowel Syndrome "Meds: Subutex 8mg SL 2x daily (recovering addict), Bentyl 20mg oral as needed up to 4x daily. I have irritable bowel syndrome flare-ups randomly, depending on stress level, caffeine/nicotine/stimulant intake, etc. The first few months, one 20mg Bentyl stopped a flare dead in its tracks. Now it doesn't and I have to double dose, because when I flare, the pain is so severe that I begin vomiting, sweating, shaking, and cannot function at work. The double dose is effective, but causes blurred vision, cognitive impairment, and a general feeling of being 'disconnected' or 'high', minus any kind of euphoria. Going to discuss this with my PCP."

For Irritable Bowel Syndrome "I have battled IBS for years, have seen several doctors with no luck. About a year ago, I had horrible stomach/abdominal pains and diarrhea and ended up in the ER. The doctor gave me Bentyl and Zofran. Within half an hour, the cramps disappeared, and I was able to relax. When I followed up with my primary doc, he put me on a normal daily dose of Bentyl, and it works great for me. I now only take it as needed, and the only complaint I have is that it definitely blurs my vision, but it keeps me functioning and works pretty quickly when needed."

For Irritable Bowel Syndrome "Unfortunately, I have not had a good experience with Bentyl. I've had severely blurred vision after just 3 days of taking 10mg 3 times per day along with extreme bloating. I have been extremely uncomfortable and stopped taking the medicine. Hopefully, there is something else available to help my symptoms."

For Irritable Bowel Syndrome "It was great for the first day or so, but then I was struck by horrible side effects. Cramps in my legs were so bad I could hardly walk, and I literally didn't get a wink of sleep at night due to the pain and restless legs. I also experienced blurred vision and very bad nausea. I would advise a low dose at first to see how it goes, but beware of side effects."

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 "Just started taking it, and it really hasn't helped much at all. One nasty side effect I'm having is that every time I take a pill, I have a fever spike that runs up to around 101, and my vision is blurred. I have no idea why it's doing this to me."

For Irritable Bowel Syndrome "This medication has been huge for me. I don't run to the restroom as often. My pain is way better. The only side effects I have are dry mouth, loss of appetite, and blurry vision."

For Irritable Bowel Syndrome "I took this without ill effect for several years, then suddenly it became a bad migraine trigger. The blurry vision became intolerable, so I had to stop."
