For Constipation "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 childbirth. 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 being's system."

For Constipation "After many trips to the doctor, urgent care, and more, I finally discovered the wonders of Dulcolax. Every other laxative 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."

For Constipation "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 4 pm, and it is now 10:30 pm, and the pain is truly unbearable. It feels like your insides are being 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."

For Constipation "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 grimaced 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 poop, their toilet obliterated, and their favorite child dead.' If you have any desire to force yourself through hours of grueling spats of gas and poop, this is for you. Hope you've got some Desitin."

For Constipation "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 to 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."

For Constipation "Every time I eat pizza, I really get bunged up, so this time I took a Dulcolax after eating said pizza, which was delicious, by the way. Twelve hours later, lying in bed, I did some really stinky trumps, and I got a twinge in my lower region, which I initially thought was mild period pain, but I realized it must be time to poop, so I ran as fast as I could to the toilet, and as soon as I sat down, the whole world fell out of my butt. A mixture between runny and soft poops, the whole toilet bowl is pebble dashed, so make sure you have bleach handy. I would definitely recommend it, but to those taking two or more tablets... what were you thinking!!??"

For Constipation "DO NOT TAKE THIS..... I had been constipated for a week and needed something to help with that. I took Dulcolax 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."

For Bowel Preparation "I wanted to weigh in on the bowel prep experience. I read a lot of these comments and was terrified about what might happen. I stayed well-hydrated all day and took 4 Dulcolax at 3 pm. Then, at 5 pm, I started the process of drinking a whole bottle of Miralax. By 3:45, I had a standard BM. From then on, I had slight bubble guts and an occasional gas pain. By 7:20, I had completed my Miralax prep for the evening. I had two small watery BMs around 6 and 6:45 pm. The serious action started around 7:45 with large, urgent, watery BMs about every 5-10 minutes until about 8:30. One more at 9:30, and a smaller one at 11:30. During that first active window, I felt pretty rough. I felt nauseated but never threw up. I was exhausted and couldn’t really focus. I stayed as hydrated as I could. So, bottom line is that it’s no picnic, as I was certainly emptying my bowels fast... but neither was I writhing on the floor in pain. Whew!"

For Constipation "Took two of these Dulcolax at 4:30 pm as I had been suffering from constipation for a few days. Had a normal bowel movement at 6 pm, and I thought they'd done their job. That is until I woke up at 12:30 am with the worst cramps imaginable. This was followed by numerous further explosions at 2:30 am and 4:30 am, 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 11:30 am the next day, and my stomach cramps are still very much there. These work, but at a high cost!!"

For Bowel Preparation "I've taken Dulcolax before, but the most at one time was 2 tablets. I'm having a colonoscopy in a couple of days, and I absolutely cannot believe the instructions. Two days before the procedure, I am supposed to take 5 tablets at 4 pm, 5 tablets at 6 pm, and 5 tablets at 8 pm. The same the next day, followed by two enemas on the day of the procedure. If people are having terrible pain taking 4 tablets, how on earth am I supposed to take 15 within 4 hours? I was given a prescription of Zofran for the nausea, but I'm afraid I will end up in the ER if I take 30 pills in two days. I'm thinking about cutting back on the Dulcolax dosage and adding Miralax or Magnesium Concentrate. Has anyone ever been given instructions to take such a high amount like this, and did they survive?"

For Constipation "This laxative is positively wretched. I took 2 pills around 8 am this morning due to feeling icky after only a few small BMs over the last 10-ish days. Three bottles of water/2.5 hours later and I already have an excruciating headache, nausea, chills, cramps, and increasing lower back pain. I decided to check online when my hands and face started 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 on my bathroom floor shivering and 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."

For Bowel Preparation "I have used the product over 7 times now, and it has worked like a charm each and every time. I take 3, and drink about 24 oz of water. I take 3 because I'm 280 lbs. Take it on a Sunday afternoon, don't make any plans to leave the house, and by the evening it's all done. I usually end up going to the bathroom 3-4 times. First 2 are usually soft movements, any after that it's just getting rid of the excess water. I think people that are getting bad cramps is they are not taking enough water with it. Try more water, see if it helps! I have had zero side effects using this product."

For Constipation "I took two Dulcolax pills at approx. 10 a.m. with a glass of water. Then I read the reviews and was terrified at what I was in for. But for the entire day, I felt absolutely no symptoms and no bowel movements. I wondered whether this was going to work or not. Finally, at about 2 a.m., I had tummy rumbling and gas, but really that’s it. But at 8 a.m. the next day (22 hours after dosing!), I woke with my tummy rumbling and feeling the urge of diarrhea. I rushed to the bathroom. A few minutes later, I still had the urge to diarrhea again. I’d say between 8 a.m.-1 p.m., I had diarrhea about ten times. It was a lot. But the good thing is, any discomfort was minor (my stomach rumbled all day, and I kept feeling the urge to diarrhea), so I stayed home until the feeling finally passed. I did not experience nausea, vomiting, cramps, or anything like many reviewers. Other than the 5 hours or so of diarrhea and tummy rumbling, this was really painless and effective!!!!"

For Constipation "I took 2 tablets with my meal (6:30 pm) 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 quickly 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."

For Constipation "WOULD NOT RECOMMEND. I took 3, like the box said (10 pm). I took it because I haven't been able to potty for a week. Around 2 am, I woke to my stomach cramping so bad. I got up and went to the bathroom, and nothing happened. 30 minutes later, I felt even worse, so I went back to the bathroom. At this point, I'm nauseated and very lightheaded, and once I got to my destination, sweat was literally pouring off me like I've been digging holes in the desert with a temperature of 115 outside. With all of this going on, I went into an anxiety attack, which now it's hard to breathe. Thankfully, it FINALLY released itself. The next morning, I felt like I've been run over by an 18-wheeler and exhausted beyond belief and shaky. Definitely not ever taking this again."

For Constipation "I'm an alcoholic, so I am prone to constipation from dehydration. On the Bristol Stool Chart (that is a chart the doctors use to classify your poo), I’ll often have type 1 stools, which are like passing rocks out of your butt and take an eternity while tearing your rectum apart. So I took 4 Dulcolax pills, and over the course of the day, things improved, but I did feel some nausea, and I had 4 BMs. So it will definitely make you poop. I normally drink coffee in the morning and then just go every morning once. On Dulcolax, as I wrote, I went 4 times in 1 day, but it did change the stool shape positively. On the Bristol chart, I probably ended up at type 3 (normal) by the evening, so I generally think it’s a good product if you suffer from pooping rocks like I do. That is the worst feeling in the world, and this will fix it, but you will go multiple times in the day. Regarding the other reviews, I think you need to be type 1 constipated for this product to be useful. Otherwise, it'll likely cause massive diarrhea."

For Constipation "I tried it and took 2 pills with lots of water and ended up staying up all night, crying from severe abdominal pains. Then throwing up with the pain becoming worse. Finally, 12 hours later, while still in pain, I had the most painful bowel movement. I'm still on bed rest from the cramps, and it hurts to stand upright. If you choose to take this, please be careful. It's effective but at a painful cost."

For Constipation "I had been constipated for several days and decided it was time to try a laxative. I picked Dulcolax because it advertised as 'gentle relief.' This was the beginning of my doom. I took two at bedtime because of the suggested dosage. I woke up a few hours later in a cold sweat with some of the worst stomach cramps ever. I rushed to the toilet and had a massive explosion of diarrhea. I honestly thought my organs were leaving my body, it felt like a never-ending evacuation out of my rear end. I felt horrible the whole time and started to get dizzy. I ended up passing out on the toilet and falling into the bathtub. Upon waking up, I stood up to get myself together and I passed out again. I ended up having to call an ambulance and went to the ER, where I had the pleasant experience of explaining to every medical professional I came in contact with that I had passed out while pooping. It did thoroughly clear out my bowels, but I would not wish this nightmare upon anyone."

For Constipation "I hadn't gone for 4 days and decided to try Dulcolax. I am 5'1" and 120 lbs. The bottle says anywhere from 1-3 pills, and my constipation was pretty bad, so I decided to take 2. Worst mistake of my life. I took the pills at 2:00 pm, and by 6 pm I had the most terrible cramps I have ever felt in my entire life. I was shaking, cold sweating, and felt like I was going to throw up several times. Hours later, and I'm still having terrible diarrhea. It works, but the side effects are too much for me."

I thought I was dying. I was too sick and embarrassed to wake my husband up, so I just sat on the toilet, nauseous, crying, convulsing, hurting, throwing up, and dizzy. I was fine by 9:00 am the next morning but very weak and tired from all the labor... I mean suffering."

Boy, I wasn’t expecting the horrible stomach cramps, nausea, bloating (to the point I feel I am a few months pregnant), and I am having a hard time just getting water down. I have put a heating pad on my stomach in hopes this will help alleviate my stomach cramps and the bloating. I will NEVER ever take this AGAIN!! I would rather do an enema than take it!!"

For Constipation "I'd struggled going to the toilet for 5 days, and I'm normally very regular with minimal effort once a day. I grabbed some Dulcolax from the supermarket and took 1 at 10 pm immediately before getting into bed. I then read reviews and instantly started to regret taking it - but I shouldn't have done! I woke up at 5 am with some cramps, no worse than period pain, and some tummy rumbles. I got up to the loo, passed A LOT of gas, and then spent probably 15 minutes emptying my bowels while playing a game on my phone. Solid at first then liquid. 5 days of buildup evacuated - it was glorious! I did feel a bit sick, but once I was done I was back in bed and asleep by 5:30 am and then got up at 7 to start my day as normal. No further issues. It did the job! Definitely only take ONE. I'm writing this review for anyone else who, like me, has bought/taken Dulcolax and read these reviews and is now consumed with fear/regret. Follow the instructions and it is perfectly fine."

For Constipation "This past Friday night, the 21st of Feb, I took one Dulcolax for constipation as per directions on the box, which said 1-3 may be taken. It was about 9:00 pm when I took it. By about 10, the pain and nausea started and grew steadily worse. By 11, I was in agony, sweating profusely, so much so my hubby had to peel my pajamas off me, they were soaked. Finally, yesterday a BM, but still cramping today. It's Sunday, and it's still painful, the nausea and acid bubbling in my throat, sweating, and those cramps that I can feel in front up to the bottom of my ribs, so it's probably intestines, and even my back feels like I was hit with a bat across the ribs, same location, under the ribs. Please take care using this product, drink plenty of water. Most of us on these reviews have given you the basic info we felt we needed to call 911. As women, we are strong, but this brought me to my knees. I took it only once, and it was the lowest amount, just a horrible experience."
