Dulcolax (bisacodyl) "I feel like my experience would be different to someone who only suffers from occasional constipation. I unfortunately get constipated to the point I can’t remember the last time I had a bowel movement. Dulcolax works for me but it is the most intense painful experience EVERY single time. And yes I have used it more than once because clearly I have a death wish. Within 2 hours the cramps start. The type of cramps where you can’t lay down, but also you can’t sit up straight because they are ripping apart your insides. By morning I am awake at 7am unable to sleep because of cramps. It usually takes 2 hours of excruciating pain to be able to actually go to the bathroom, and after that your running to the toilet once an hour quite a few times. Fun fact 24 hours after I took this stuff I trusted a fart and crapped my pants :) so taking this is not a fun time, but everyone’s experience is different. Just ... don’t trust your farts for a while."

Dulcolax (bisacodyl) "Whoever created dulcolax - well I don't know what they were thinking. I took three pills at around 3:30 pm. By 7 pm I started to feel ill, I had a stomachache and felt like I was going to throw up. Flash forward 3 1/2 more hours and my lower back felt like it was it on fire, my heart was palpitating, my legs were shaking, I had horrible cramps, and felt so feeble that I could barely move. A half an hour later is when all hell broke loose. It was a five hour ordeal. I was butt naked on my toilet seeing stars unsure if I was going to throw up or poop at any given time. During these five hours I migrated between writhing around on my bathroom floor and sitting in the toilet. I would have called an ambulance but I couldn’t walk to get my phone from my room. I thought life was going to be over."

Dulcolax (bisacodyl) "I am a healthy 23yo female, 5'6'' 132 lb. This time I had incomplete evacuation for over a week and a change in schedule, so I felt blocked up. I took a Dulcolax at 11:30 hours and drank the usual amount of water I do in a day (I drink over 130oz on a normal day) and added some lemonades to help my intestines pull in electrolytes. I did feel some rumbling but that was very mild but no BM. The next morning I had 2 BMs within 3 hours and I was all clear. No side effects, no diarrhea either! Guys, BIG ADVICE here, always under dose - start with one if you're self-prescribing or go with what your doctor says. And drink huge amounts of water. Throw in some juices, electrolytes, and you'll have the gentlest evacuation ever. I hope my review helps those having popped a few pills and waiting up for the 'lighter' day! Drink water while you wait, cheers :)"

Dulcolax (bisacodyl) "After I took Dulcolax yesterday afternoon I got online to check reviews and ended up TERRIFIED, so I felt compelled to leave a review too! I took 1 pill at 3:30pm yesterday, and had a soft BM at 4:30pm. I made sure to sip 25+ oz while I waited for it to work. Bed time came and I was scared to sleep. I woke up at 3:30am to tummy rumbles (but no cramps or pain), and had another BM around 5:00am, this time even softer. Again at 7:30am, and at that point it was diarrhea. Overall, I would say it's been an okay experience. It did what it was supposed to do. I have a headache this morning, and I'm tired, but I think it's because I stayed up reading reviews and was stressing myself out! So for the people like me, who are doing the same exact thing right now, I wanted to leave a good experience here too. :)"

Dulcolax (bisacodyl) "NEVER using this stuff again!! This stuff is awful!! I wish I read the reviews before taking this. So here’s my story, I can never poop I’m lucky if I go twice a month, and I had enough and wanted relief. I tried miralax and benefiber and neither worked so I decided to try dulcolax. I took 2 of these teeny tiny bombs at 9pm, woke up at about 4am having the WORST cramps ever, felt like I was in labor. It lasted all up until 7am and I got up to try to poop, I couldn’t even push because I was hurting so bad. Then finally it all fell out. Complete diarrhea, then at the same time I got SUPER nauseous and threw up I got super hot and clammy and got super dizzy and saw stars I actually passed out on the bathroom floor mid crapping. I couldn’t get up I was so weak and everything was spinning. For the entire day I had diarrhea every hour or so, it wouldn’t stop. I had to call into work I was so sick. I could barely eat anything. I then got a raging migraine from it all."

Dulcolax (bisacodyl) "After suffering from 2 weeks of constipation, I bit the bullet and took 2 of pills around 3:30pm. By 7pm I had a solid bowel movement and thought "great, problem solved." How wrong I was! Fast forward to 4am, I woke up soaked in sweat and feeling like my stomach was being ripped out. Barely conscious, I managed to crawl to the toilet just in time. Then all hell broke loose! The world fell out of my butt in the form of what can only be described as molten lava for the next hour and a half. This was followed by bouts of nausea, heart palpitations and feeling like I was going to black out. The next day was spent feeling like I'd been hit by a train. These pills are unbelievable and only a masochistic would take these more than once. How are they legal?"

Dulcolax (bisacodyl) "Sooo after reading all the reviews on here I figured I’d share my story. I’ve taken this drug a few times. First two times I had mild constipation and shared the same experience as most of you on here have had. Horrible cramping, sweats, explosive bowel movements, laying on the floor and overall just wanting lfe to be over! The next two times I had taken it I honestly swore I’d never take this drug again but this time my blockage had lasted over a week. That feeling alone is scary think that your intestines will explode. So I took each time right before bed. Woke up early in the morning with cramping but immediately released in the toilet. Diarrhea for the next few hours but tolerable. So to conclude this is a great product for severe constipation, I’m not talking a 3-4 days without a bowel movement, I’m talking a week or longer. Try other outlets like collace or Metamucil. Ducolax should be a last resort after a long period without. Hope that helps someone :)"

Dulcolax Laxative (bisacodyl) "I took the pills at around 2am and I was awoken at around 7.45am with the sound of a demon noises echoing around my bedroom, in fact the noises was my stomach roaring and bubbling like a volcano about to erupt. I had mild cramping and thought I’d better get to the bathroom. Sitting on the toilet, I began to involuntary heave. This went on for around 20 minutes. I clenched my cheeks together and out came a watery splash of sheer stink. I thought to myself “This can’t be it?”...and I was right. I was back and forth to the toilet all morning and my butt felt like a fire breathing dragon. Every time I got back into bed for a rest, I lay in wait for lucifer himself to take over my sphincter. I lay in bed just reevaluating my life. I had visions of the emergency services coming to my rescue as I lay in a pile of my own excrement begging the lord for mercy. Only take these if you fancy a trip to hell and back."

Dulcolax (bisacodyl) "Took two tablets at about 8am, expecting some gentle movement in a few hours. Next joke? Before 9 I was totally incapacitated with extreme cramps and nausea. This was closely followed by sweat pouring from my whole body, then the explosive diarrhoea described by many others. I genuinely thought I was going to have to call an ambulance, I felt like I was dying-slowly and very painfully. This product should not be sold over the counter."

Dulcolax (bisacodyl) "TIPS: Start with 1 the first time, and never take more than 2. Drink lots of water - if you are not hydrated they will make you feel nauseas. Only take for moderate to severe constipation, if it’s mild you will experience severe cramps. These DO work very well, but follow the above first."

Dulcolax (bisacodyl) "I have taken dulcolax for severe constipation twice. I suffer with constipation frequently and have done my whole life. I take movicol but recently the periods between "going" have been getting longer. The first time I took dulcolax I took 1 and it had very little effect. Yesterday it had been almost 2 weeks since I last moved my bowels so I took 2 this morning. 10 hours later I suddenly began to feel very, very ill. Dizzy, extremely nauseated, headache, terrible stomach cramps, cold sweat, the lot. I tried unsuccessfully to move my bowels 3 times, then on the 4th time an unholy amount of poo left my body. I now feel much better. It did exactly what I took it for. Although the journey was unpleasant it was short lived."

Dulcolax (bisacodyl) "This is absolutely horrendous stuff! I cannot believe they are able to sell this in shops! I took 2 last night as I’ve been constipated for a few days, woke up at 7am with stomach cramps but managed to get back to sleep, I then woke up at 8:30am thinking I was going to puke, I ran to the toilet and it was like an explosion of diarrhea, I then came over in a hot sweat and fainted on the toilet!! Ears ringing, head spinning, dripping in my own sweat. Absolutely awful stuff, avoid!!!"

Dulcolax (bisacodyl) "Worst experience of my life I've been taking cocodemol, this has caused 10 days of constipation. Bought Dulcolax from Tesco and read instructions which was 1 to 2 tablets when needed. So I took one to be on the safe side. I took at 8pm and by 1am I was screaming in agony with severe stomach cramps that felt like contractions but 10 times worse. Tried to go toilet, nothing happened. Cramps continued constantly and the pain was unbearable. This went on for hours. I cried, rocked and screamed with the pain I couldn't even stand up straight. Finally started going toilet at 4am, sweating, shivers, nausea, i actually saw stars. I was sitting on the bathroom floor sobbing and considering ringing 999. It is now 9am. I'm still getting stomach cramps and been on and off the loo for hours so I can't leave my house, I'm freezing cold and still feel sick. I was suppose to be at work tonight but had to phone in sick because I've no clue how long these horrible side effects will last. Believe me I would much rather have stayed constipated."

Dulcolax (bisacodyl) "I was constipated so I took 2 Dulcolax Saturday night. I started having diarrhea and lots of blood with it. That continued for 36 hours. Lots of stomach cramping and vomiting. I thought it was the end of me. The cramping was exactly like child labor. I would suggest to anyone reading this review to NOT buy dulcolax. It is just so bad and should be taken off the market. I was within hours of having to go to the ER. This product is literally toxic to a human beings system."

Dulcolax (bisacodyl) "I really do not recommend this medicine. I had a pretty major surgery, so I had to take pain medicine. Because of this, I became constipated. I went for a few days without any bowel movements. I think I took Dulcolax once a day for two-three days before anything happened. I woke up, and suddenly felt like I had to go to the bathroom. Then the cramps started. The cramps were horrendous. I was shaking from chills, and sweating, and I was doubled over clutching my stomach. I felt nauseous, and I felt like I couldn’t sit still. Not much was coming out, so I ended up taking a suppository which finally did the trick. The cramps, and constant running back and forth to the bathroom lasted for HOURS. I would rather have my surgery 10 times over than take this medicine again."

Dulcolax (bisacodyl) "Took 2 pills and woke up about 3 hours later in excruciating PAIN! It felt like someone was stabbing me in the stomach and twisting the knife. I probably did more vomiting than number two. Cold sweats, confusing and profuse pain. I just wanted to pass out to get some type of relief! At one point the pain had gotten so bad I asked Jesus to come take me out of my misery. There is no way that stuff should still be on the market."

Dulcolax (bisacodyl) "Idk why this drug is getting bad ratings for effectiveness. It's extremely effective at it's intended purpose. I wouldn't recommend using this unless the constipation has progressed beyond the scope of using a stool softener. Because Ducolax is NOT a stool softener. It's a STIMULANT LAXATIVE. That means your gastro intestinal muscles squeeze really hard to get rid of anything inside Please understand, this is not for tum-tum discomfort, it's for clearing a blockage, and it will ABSOLUTELY clear your constipation. As with any type of medication, one should assess one's tolerance the first time taking this. The directions say 1-3 tablets, so start with ONE. Don't START with 2 or 3!! Also, expect some cramping and other side effects. If you take the right dosage, it will likely be unpleasant, but, tolerable. Don't be surprised if you find yourself running to the bathroom a few times, because this is going to CLEAR YOU OUT. Trust me. Maybe take a personal day lol."

Dulcolax (bisacodyl) "After many trips to the doctor, urgent care and more, I finally discover the wonders of Dulcolax. Every other laxatives would give me excruciating cramping. Well Dulcolax will give you great results. Prepare yourself for a poopy situation literally. It’s like having your own private fireworks show in the privacy of your bathroom. Niagara Falls is small compared to this explosion of internal compost. Definitely a 5 out of 5 stars ⭐️ show."

Dulcolax (bisacodyl) "Had been having severe constipation so I decided to go to the store and pick up some Dulcolax. Let me tell you, if you haven’t already, DON'T take it. The box said 1-3 pills so I, of course, went ahead and took 3. I took them at 4pm and it is now 10:30pm and the pain is truly unbearable. It feels like your insides are beings squeezed to death from the inside. I’m too scared to even go lay in bed because it is just too unpredictable. Throwing up, diarrhea, overheating one minute to chills down your whole body the next, sweating so much it looks like I just got out of the shower, so light headed, seeing stars, caught myself passing out on the way to get water- luckily I was able to sit down before I lost consciousness. This stuff should not be allowed, seriously debating going to the ER. If you can avoid it, avoid it."

Dulcolax Laxative (bisacodyl) "DO NOT TAKE THIS.....I had been constipated for a week and needed something to help with that. I took Ducalex at 9:30 it woke me up in pain at 3:30. It felt like period cramps at first and I tried to sleep it off but it finally was so unbearable I went to the bathroom and couldn’t go for 2 hours. I was in so much pain that I was sweating and threw up. This is not ideal for just needing a little laxative. I truly do NOT recommend and I will never be taking it again."

Dulcolax (bisacodyl) "I took just one tablet of this monstrous drug and I have not shat my brains out like that since I had food poisoning. There I sat, arms clenching my stomach, head between my knees, defecating all of my pride in endless burning blows. My face was grimanced as war flashbacks from that one bad hotdog I ate at that sketchy waterpark coursed through my mind. All I could think of in that moment was "this is how I die. My parents are gonna find me doubled-over, covered in my own shit, their toilet obliterated and their favorite child dead." If you have any desire to force yourself through hours of grueling spats of gas and shit, this is for you. Hope you've got some Desitin."

Dulcolax (bisacodyl) "Took two of these Dulcolax at 4.30pm as I had been suffering from constipation for a few days. Had a normal bowel movement at 6pm and I thought they'd done their job. That is until I woke up at 12.30am with the worst cramps imaginable. This was followed by numerous further explosions at 2.30am and 4.30am, to the point where I had to lie on the bathroom floor to stop myself from passing out. Pretty sure my bathroom is going to need an exorcism after this. It's now 11.30am the next day and my stomach cramps are still very much there. These work, but at a high cost!!"

A mixture between runny and soft poops, the whole toilet bowl is pebble dashed so make sure you have bleach handy. Would definitely recommend, but to those taking 2 or more tablets... what were you thinking!!??"

Dulcolax (bisacodyl) "This laxative is positively wretched. I took 2 pills around 8am this morning due to feeling icky after only a few small BMs over the last 10ish days. Three bottles of water/2.5 hours later & I already have an excruciating headache, nausea, chills, cramps & increasing lower back pain. I decided to check online when my hands & face stared to tingle. This is truly a gnarly experience. I have taken laxatives a handful of times in my adult life. I wouldn’t describe any of those times as “pleasant” but, never have I felt so awful that I sat in my bathroom floor shivering & reading poop reviews to make sure I’m not going to die. The Dulcolax will be going straight to the outside garage bin as soon as I am able to walk. I’d honestly rather be constipated."

Dulcolax (bisacodyl) "I took 2 tablets with my meal (6:30pm) and then before bed read all the scary reviews. I saw that some said they didn’t have a horrible experience when drinking a ton of water, so I quick downed 50 ounces of water before bed. I woke up at 2:00 am with a slight crampy sensation and loose stools. It happened again at 2:15 am and again at 3:00 am. It is now 8:30 am and the diarrhea is the same but I have no cramping, no nausea, no shaking, and no lightheaded feelings. My stomach is still rumbling to clear itself out, but it wasn’t horrible as I thought. I think the key is to drink a glass of water when taking it, take it with food, and drink a ton of water after. I didn’t have a scary experience. I will probably never do another laxative again though unless absolutely necessary."
