Dicyclomine 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 "I have had surgeries that led to a few different infections in my bowel, which has led to severe 10 out of 10 pain when passing bowel motion. The theory is scar tissue has caused this condition, but after all the tests, there is no way to verify because it is in the small intestine. Years of pain, three trips to the ER with horrific pain, and a decade later, a doctor put me on this. This medicine has been a miracle, I have never had any pain since. I went from suicidal to being able to function and even go on vacation. However, there have been side effects. I have had blurred vision, I am generally lethargic at all times, and nausea. All said and done, the side effects are nothing compared to the other pain, but they are bad at times."

For Irritable Bowel Syndrome "This actually helped my stomach move things through at a proper pace. With gastroparesis, I stay constipated without the help of daily Miralax (sometimes that isn't enough), and when I do go, it's always one end of the poop scale or the other. But, with dicyclomine, things moved through perfectly, and I was regular again. However, I could not take it on an empty stomach as prescribed without it causing extreme nausea. I was able to take it with food. But, after a few weeks of taking it, I realized I was not only having really bad dreams but had been incredibly anxious and paranoid. When I stopped taking it, my mood returned to normal. I now only take it occasionally when things are particularly backed up."

For Irritable Bowel Syndrome "This medicine works great for my abdominal pain, but it doesn't stop it completely. I still feel nausea almost every hour of the day, but I do have a slight appetite back compared to before I started taking this. I can tell that it's working because I will start feeling more sick and more pain and realize it's been four hours and need to take another dose. A downfall that is almost making me want to stop taking this is that it makes me so tired I can't focus on anything, and I can barely function. My memory is horrible, and it bothers me a lot when I am in the middle of doing something and forget what I was doing."

For Irritable Bowel Syndrome "In 2011, I was admitted to the ER after vomiting blood. Performed an upper endoscopy (negative) and was discharged with antibiotics. From 2014 to 2017, I could not function. Vomiting/nausea, diarrhea, severe constipation, body tremors, in tears due to abdominal pain, and many expensive midnight ER trips with my worried boyfriend. I performed an H. pylori breath test (positive). I took antibiotics, but I was still having all my symptoms. I was fired for calling out sick. Referred to a GI specialist and diagnosed with IBS-C. Been on dicyclomine for 2.5 months (20mg 3x), religiously follow low FODMAP, and Miralax. I can function. Side effects: drowsy, headaches, nightmares, bloating/cramps, gas, anxiety, and mild nausea (Promethazine Rx). It's so worth it."

For Irritable Bowel Syndrome "I had severe head trauma at 20 years old, put on Bentyl at 24 after having a cyclic vomiting episode and abdominal migraines. Since I have head trauma, it affects my stomach, I feel like I'm being ripped in half. I told the ER doctor this, they gave me this IV. It stopped most of the pain and nausea immediately. Also, I never knew it wasn't uncomfortable for everyone to have a bowel movement and that cramps were abnormal. I thought it was just 'gas.' On 20 mg, 2-4 a day as needed, but I wait as long as I can to take them, it seems to last more than a day with me. With these, if I am on the toilet with cramps, I take the pill, and the cramps go away after that. I take them more as needed, but that is because I know what will trigger mine, which is some food, stress, commitments, money."

For Irritable Bowel Syndrome "I have now been on dicyclomine (Bentyl) for 3 weeks now, and it has its pros and cons. It definitely takes my stomach pains away, even without my pain medication if I don't have them on me. Most of the time, it gives me a relaxing feeling as well. But the only downside is the couple of side effects, sometimes it will make my nausea worse, so at times I will have to double up on my nausea medication, and there have been a couple of times where it made my anxiety worse. But I'm hoping these symptoms will fully go away the more my body gets used to it. I was on Librax, but the stomach medication in Librax didn't work for me, just the anxiety part of the medication in Librax helped, so there was no point in taking it. Thanks, Bentyl!"

For Irritable Bowel Syndrome "This medicine doesn’t sit right with me. It causes pretty severe side effects. (It literally feels like I’m on acid.) I have hallucinations, nausea, brain fog, shakiness, and absolutely no appetite. It didn’t even help my stomach pain. :/ Needless to say, I won’t be continuing to take this medicine."

For Irritable Bowel Syndrome "My doctor prescribed this after he decided, out of the blue, that he wasn't comfortable prescribing me Donnatal anymore. Donnatal was a 10/10 in terms of relief and lack of side effects, but Bentyl has been awful. Blurry vision, nausea, coordination problems, flushing of the skin, hot flashes, extreme dry mouth and eyes, and maybe half the time very slight relief from cramping and pain. The negative side effects absolutely outweigh the minimal benefits, especially the added nausea on top of the nausea from my IBS. I'm supposed to take 4 per day, but even 2 per day and the side effects are unbearable. I can't drive after I take this either because of the vision and dizziness issues. Hands down, one of the worst poisons I've put in my body."

For Noninfectious Colitis "Have been diagnosed with ulcerative colitis/Crohn's disease for just over a year now. Took dicyclomine from the very beginning. It seems to work pretty well getting rid of the abdominal pain. However, because I am on so many different medicines (10), I cannot say for sure which medicine helped with what or caused whichever side effect. I have experienced nausea, lack of appetite, drowsiness, dizziness, insomnia, dehydration, and severe headaches."

Dicyclomine for Irritable Bowel Syndrome "Just recently started taking. About 2 weeks now. I'm beginning to have some side effects, but, in general, it has cleared up some of the stomach drama except the nausea. I don't like being sleepy all the time, but I feel better, but not 100%."

For Irritable Bowel Syndrome "I have IBS with severe cramps, nausea, and sometimes vomiting, with episodes waning and waxing over 1-3 hours. On this medication, dicyclomine, the cramps may not be as severe, but the nausea lasts longer - which means I usually end up vomiting eventually. Cramps are not as severe, but last 4-8 hours. Would rather suffer through the episode and get it over with than take this med and draw out moderate symptoms for most of the day."

For Irritable Bowel Syndrome "Crohn's for 16 years, recent IBS diagnosis. This medicine was very effective 18 months ago. I went off it for 2 weeks 6 months ago to see if I still needed it, and thought it was still helping. I didn't know the nausea, extreme tiredness, and weird head symptoms (like I drank too much coffee/high, dizzyish) could be related to this med since I'd already been on it for a while. The nausea and weird head symptoms got progressively worse and more persistent where some days I'd just need to nap right after waking and was not functional, while trying to raise 4 young kiddos. Thank God, I finally eliminated the dicyclomine after changing many things about my life. Now those symptoms are gone. Still IBS symptoms that I will deal with for now."

For Irritable Bowel Syndrome "Very effective, but the side effects can be unpleasant. I usually get a very dry mouth, a little nausea, and a mild headache. But I'll happily take that over excruciating cramps."

Dicyclomine for Irritable Bowel Syndrome "I have been on this for at least ten years, and to this day it still gives me nausea and dries my mouth out terribly. They wanted me to take up to 4 a day, I can barely take one."
