Bisacodyl for Bowel Preparation "I took two at 8 pm (was supposed to take 4 but didn’t because I was already feeling the effects of the Miralax prep). I’m so glad I only took two because I’d probably be passed out with 4. I woke at 4 am with intense gurgling, burning, and nausea. I thought I was having a panic attack, and maybe I was having one because I was still not prepared for how this medication would work. I’ve had pressurized watery stool 4-5 times in the last hour, and I don’t have a clue where it’s even coming from, all the while my stomach was burning like it was going to melt. This isn’t gentle. I plan on letting my gastroenterologist know that I’m too sensitive for this medication. It worked, but at quite the cost to my mental health."

Bisacodyl for Constipation "This was my first time taking this medication, Dulcolax. I was constipated from Saturday until Wednesday the next week. I gave this a go without reading reviews. I took 2 pills at 2:30 pm. At about 6:30 pm, I had the tiniest, most insignificant bowel motion (BM) ever, followed by another at about 8 pm. I fell asleep at 10 pm and woke at 12:40 am with the most painful stomach cramps/gas pains I'd ever experienced. I sat on the toilet in the dark, pushing with each stomach cramp. I must have been more focused on the pain because, to my surprise, I had been passing the largest pile of semi-solid stool in my life. These cramps came and went as I passed 3 more massive piles of stool. I have a very high pain tolerance, but these cramps were BAD! By 1:45, they ended, and I felt like I could fall back asleep. Overall, I probably would only take this if you absolutely HAVE to take a laxative. But be prepared for cramping."

Bisacodyl for Constipation "I'm a recovering opiate user. I'm used to the occasional constipation that comes from my addiction, but I entered a methadone recovery clinic, and this is when my constipation became severe. Long story short, after almost a week and a half, I was miserable and needed relief fast. My mom had Dulcolax and gave me THREE. I went to sleep thinking all would be okay. Only to wake up four hours later with SEVERE stomach cramps. So severe that I woke my grandmother sleeping in the next room. She was so worried about me that she was actually in the bathroom with me, putting cold towels on my head and back while I was on the toilet and started throwing up in the trash can in front of me. I finally passed the stool but had diarrhea for 24 hours after this experience."

Bisacodyl for Constipation "I took one Dulcolax last night at about eleven p.m. I have taken it before without the problems I am having now. By four a.m., I was having severe stomach cramping, but no bowel movement. I experienced horrible cramps, nausea, bloating that would not relieve for hours, and now it is almost six p.m. the following day, and while the cramping is much less, I still have an upset stomach. I considered going to the emergency room last night, but I really could hardly move and knew there was little they could do for me there. I will not ever take this stuff again! The packaging says it is 'gentle.' Good lord, no, it isn't!! I've taken magnesium citrate before and did not experience the type of cramping and pain I had for hours early this a.m. with Dulcolax. Will never take this again, I am still not feeling well almost twenty-four hours after I took the one pill."

Bisacodyl for Constipation "The first time using this product was after having not gone for about 5 days. Needless to say, I was a little desperate to get something that worked. I took 3 pills, which were effective within 3 hours, accompanied by pretty bad stomach cramps, but nothing I couldn't handle. After having the same problem, I decided to try Dulcolax again, having it been successful the last time. WORST DECISION EVER. Not only did it take almost 16 hours to start working, it came with severe nausea and cramps before any success. It's been a day, and I still can barely eat without experiencing serious diarrhea! I'm definitely not constipated anymore, but it wasn't worth constant bathroom trips at school. Only use if you're okay with the side effect, and ONLY TAKE ONE."

Bisacodyl for Constipation "I suffer with IBS. I usually use Senna laxatives but was recommended Dulcolax as a stronger option. I took one just after 12 and was woken up at 4 am with strong stomach cramps. I remained constipated for at least another hour but was unable to sleep as the pain in my stomach and back was too much. I turned grey in the face, began sweating, and feeling so weak I thought I was going to pass out. I received some relief eventually, but it was really not worth any of the symptoms I went through. I will stay with Senna, they give better relief with less pain."

Bisacodyl for Constipation "Took two Dulcolax tablets at around 8 or 9 pm. It has helped with constipation, but I am in some serious pain from the stomach cramping. It's 3 am now, and I have not slept due to the cramps! Yes, it somewhat helped with the constipation, but the stomach cramps I'm experiencing are ten times worse than my discomfort beforehand!"

Bisacodyl for Constipation "I took this because I was having an ultrasound the next day, and my doctor wanted me reasonably cleaned out. I took 2 tabs at 8 pm. I woke at 4 am with bad stomach cramps. I moved into the bathroom for the next hour, where I experienced crippling stomach cramps, nausea, and vomiting (mostly dry heaves as my stomach was fairly empty). I actually thought about calling 911. That bad! I was burning up and sweating profusely - and I typically never sweat. It was the worst I've ever felt in my 56 years. The product worked. Several hours later, I'm still with some diarrhea, and the other symptoms are somewhat better, but I'm never, ever taking this poison again!"

Bisacodyl for Constipation "I took three last night at 9:30 pm and went to bed. I woke up at 2:00 am with the most intense, painful cramping I have ever experienced. I was also super gassy, and my tummy was bloated and felt hard. The pain lasted for two hours! I was expecting some cramping, but not to this extreme level. I tried to go #2, but nothing happened, so I went back to bed and was able to get back to sleep at around 4 am. I woke up at 6 am feeling the need to use the toilet, but also feeling nauseous. I threw up and felt so ill, again, no easy BM, just lots of discomfort and cold sweats. I woke up at 9 am and tried to use the toilet, again, not an easy BM, but I could feel I had to go! Finally, at about 11 am, I had diarrhea. I tried again at about 12 pm feeling the need to go, but nothing was coming out... again!! I feel so sluggish and tired, I still am somewhat plugged up, and my stomach is so sore. I will probably stick with Senokot or eat lots of prunes or high-fiber cereal from now on."

Bisacodyl for Constipation "I'm on a diet that has restricted my fiber intake, so I was getting a sore stomach from constipation. I figured a laxative would be a good idea and went to the pharmacy. Honestly, this stuff looked pretty unassuming until 7 hours later. I'm having severe stomach cramps, explosive diarrhea, and nausea. Once I stopped pooping the first time, I quickly went and got my phone and a water bottle because I knew I was in for it. For anyone going through this, I found during the 'breaks' it helps to stand up and drink some water, just to get it over with."

Bisacodyl for Constipation "I have been overseas for nearly a month now and started experiencing stomach cramps every morning for about a week and then continued with no BM. I'm 19 and have never had issues like this before. Possibly from the food I've been eating, not sure. Went to a pharmacy here in Thailand and Dulcolax is what they gave me. Took 2 pills at 7:30 pm and went to sleep and woke up at 2 am with stomach cramps, painful but bearable. A BM followed where it started off normal before ending in diarrhea. Went again about 10 minutes later and am now back in bed at 4 am feeling as though I'll get back to sleep with little pain, although my stomach is still rumbling. Not sure what all the fuss is about, it's done the job and I feel good that my bowels are clear."

Bisacodyl for Bowel Preparation "I read all these reviews before I took the tablet. I have to be honest, from all these reviews, I was in tears, not wanting to do the bowel prep. I took 1 tablet, drank 2L of water, and went to bed around 9:30 pm. Woke up at 7:30, went to the toilet 2 to 3 times, slight stomach ache, but nothing really. Hardly any pain, just needed to poop pain. Do not have this with a meal, do not crush the tablet, do not drink it with milk, and make sure you drink a lot of water. But honestly, it is not too bad in my experience. You can get this drug from the shelf at the chemist, they wouldn't have it accessible if it was truly that bad."

Bisacodyl for Constipation "Hadn't had a bowel movement for several days, so took two of these tablets going to bed one evening. I woke up with stomach cramps that lasted for hours, they became worse and worse and can only be described as rather unbearable. Yes, they made me go to the loo, but the pain was not worth it!"

Bisacodyl for Constipation "I took 2 yesterday at 11:30 pm, then 5 minutes later I read the reviews, and to my dismay, the reviews were terrible. I started to panic and wish I didn't buy it! So I was up all night thinking I'll have the worst stomach cramps and vomiting. I woke up at 4:00 am and went to the toilet. No cramping. Then at 6:00 am, no cramping, but did let everything out! I was worried for nothing, but because of the reviews, I will be sticking to natural tea."

Bisacodyl for Constipation "I took 1 pill at 4:00 and had drunk an entire water bottle prior to taking it. I then came on here and read all the reviews and got absolutely terrified because of how many bad experiences there were. I, however, didn't have a bad experience. With this medicine, you MUST drink a lot of water after taking it. I drank another 3 water bottles after taking it. Around 9:00 p.m., I had a regular BM. The next day, around noon, I experienced on-and-off stomach cramps. They were extremely mild and did not cause a lot of pain. An hour later, at 1, I had another BM. If you drink water, you don't have bad side effects. The one issue I had was that the timeline was not predictable, as I didn't get the full effects until 20 hours after taking it."

Bisacodyl for Constipation "I took 2 pills for constipation at 4 pm on Tuesday. By 1 am, the stomach cramps and nausea started. Fast forward 27 hours from first taking the pills, I've vomited 3 times, went to the toilet at least 15 times (12 were only liquid), and the stomach pains and nausea are still intense. I delivered 3 children without any form of painkillers, and this feels as if I were 6 cm dilated in active labor. Do not take this product. Please don't give it to your child or elderly person."

Bisacodyl for Constipation "Dulcolax has helped, but I agree it comes with stomach cramps. For fast relief of constipation, yet I feel much easier on the stomach is magnesium citrate. Find it anywhere. I have also found it very helpful if you feel you have a hard stool to pass. It may take hours, but eventually, it will break down stool, which I find to the point it's not terribly painful to pass. For regular constipation, the results are usually very quick. For hard stool, it may take a good portion of your day, but if you can take the time to plan on being near the bathroom, because you will pass other stools before you pass the hard stool, and eventually the hard stool will break down."

Bisacodyl for Constipation "Avoid like the plague. Took two yesterday midday and woke up with the most unbelievable stomach ache I have ever had. Screaming in pain, hubby wanted to take me to the hospital. Never felt anything like it, it was so bad I can't even put it into words. Then came the nausea and then the vomiting. Two hours later, I am a crying mess and then finally got off to sleep. To add further insult, there was no 'movement', and I have felt bloated and like I have been gut-punched all day. Save yourself the agony and get some prune juice."

Bisacodyl for Constipation "This drug is awful! Gives me bloating and not a very good laxative. I took 1 pill unlike the other reviews, I didn't get terrible diarrhea. But it woke me in the night every time I took it (maybe I took it 4 times) with terrible pain, like my stomach was burning and on fire. So sick, sick, sick and not sure whether I would throw up or what was going to happen. Sweating, shaking... the stabbing pain in my belly was so bad. Anyways, I am going to throw the rest of the package out to avoid taking it again. One time I was so super constipated I took 3 pills, and less than an hour later I got gas and diarrhea, but no abdominal pain. Then I kept waking up in the night and rushing to the bathroom, I almost pooped the bed!"

Bisacodyl for Constipation "I take this every other month when I get constipated, took one last night because I didn't have a BM for 5 days, figured it would be like all my other Dulcolax experiences, just bearable cramps and stuff, but I WAS WRONG. I woke up at around 11 with the worst stomach cramps ever, I barely made it to the toilet, no BM, just the cramps. I started to sweat buckets, I'm not even kidding, like the sweat just dripped like I just finished an hour of interval training. Sat for around 20 mins with nothing but the PAIN, thought I was gonna die. The weird part though was that I fell asleep (or maybe passed out, I don't know), I just woke up and felt like I slept for 30 mins. Thought it was over but got another wave of cramps and then finally had a BM."

Bisacodyl for Constipation "I have regular constipation, so I use Dulcolax about two times a week. I always take 2 tablets and always about 2 hours before I go to bed. Any discomfort is whilst I'm asleep. I wake up in the morning knowing I need to empty my bowels, but no severe stomach ache. If I take it earlier in the day, I do notice stomach cramps, so ALWAYS TAKE AN HOUR OR SO BEFORE BED."

Bisacodyl for Constipation "I beg of everyone to think twice before taking this pill. I am 20 years old and took one of these a couple of years ago after being constipated for a week, and remember laying on my stomach holding onto my bed for dear life with all four limbs-swearing I would never take one again. I proceeded to go to the bathroom for hours-in pain unlike anything else I experienced. This month, I was on vacation and had barely gone to the bathroom for 24 days!! So I decided I'd try this before going to the doctor! I woke up last night with such bad stomach cramps, almost not making it to the toilet before throwing up and pooping myself at once!!! Puking black stuff up-which I am still very confused about!! I have not moved from bed all day, sick as a dog!"

I experienced the worst stomach cramps and projectile vomited a lot! I woke up at 3 am thinking I needed to go to the ER, but then I read the reviews and realized I was not the first person to experience these effects. Don’t buy this medication! Trust me, you’ll regret it!"
