For Constipation "Exactly two weeks ago, I underwent major surgery, leaving me immobilized at just 23 years old and confined to bed rest. To manage the pain, I was prescribed opioids, but they caused severe constipation. Despite trying several laxatives and natural remedies, the issue persisted, so I purchased a Dulcolax suppository for quick relief. At 6 pm, I inserted the suppository, and within ten minutes, I was hobbling on crutches to the toilet, bracing myself for a severe bowel movement. It was the most agonizing and unyielding bowel movement I have ever experienced. To top it off, six hours later, I suddenly felt extreme nausea, pain, and began vomiting up everything I had eaten throughout the day. As soon as my stomach emptied of food and liquid, I was dry heaving over the bed, but nothing came out. This was by far the worst experience of my life, and I would rather relive the post-surgery period than go through it again. Therefore, I urge everyone to exercise extreme caution when taking Dulcolax suppositories."

For Constipation "I took 2 pills around 11 a.m. and now I am experiencing severe cramping. I just vomited as well. Worst feeling ever. I only had one BM so far but didn't expect I was going to feel this way. Never trying this stuff again. Big mistake. Smh."

For Constipation "Twelve hours after I took it, I had intermittent cramping, then an urge to go. Didn't go, but did vomit twice. Cramping intensified and I was reminded of giving birth. It really hurt. First poop was average, followed by loads of diarrhea. Make sure you can be home all the next day if you're taking it at night. You need to rush to the toilet. If I ever have to do this again, I think I'll try a suppository. But it worked!"

For Constipation "So first time using this yesterday; I hadn't had a proper bowel movement in almost a week. I took Movacol religiously as a kid, so I assumed two little pills couldn't even budge, but what the heck. HOW WRONG I WAS!!! I took them at 6:30 pm, and by 11 pm I was dripping with sweat & in excruciating pain (I'd always dealt with cramps, but this was a whole new level of pain). I was having severe contractions and tummy rumbles with no signs of movement for hours. Lots of puking and going from couch to floor to try and get comfortable. I got my partner to call the ambulance, as I was convinced I'd ruptured an organ or something ridiculous. The pain subsided, and I called the ambo off and went to sleep, woke up at 4 am and my butt was a literal tap, no more cramps though! Will be throwing this out; this should be prescription only AT LEAST! Also, pro tip for cramps: sit in child's pose and hug a pillow that's folded in half. Or sit under a hot shower, only two things that stopped the pain."

For Constipation "Took one pill at 12 am and was relieved at 5:30 am. Extremely painful intermittently for several times to get the job done (the effect ended by 7:30 am). It hurt so bad it even made me vomit the first several times while I'm on the toilet. Still being grateful that it works for me, but I would not recommend people to try it. I suggest you have a bucket handy in case you need it to vomit into while on the toilet."

For Constipation "I took 2 tablets for constipation. A couple of hours after taking the medication, I began having severe stomach cramping, nausea, vomiting, and diarrhea. While it did help me go, here I am three days later and still vomiting. I will not be taking this medication again."

For Constipation "I usually stay with magnesium for constipation, but this time I was out of town and forgot to bring the magnesium. So I went and got Dulcolax. Man, what a huge mistake. I took 3 pills around 8 pm, thinking that should get things going. Woke up around 3 am with the worst stomach cramps, went straight into the toilet and started to vomit. This lasted about 6 hours with no poop. About 4 hours later (not to be gross), it exploded out the bottom, burned like hell. Finally, after about 16 hours, it all stopped. DON'T EVER TAKE THIS STUFF, IT'S NOT GENTLE."

For Constipation "I don't get your comments, people. Some of you are taking 2 or 3 pills and complaining you're dying, of course, you are going to feel double the effect on that dosage. One pill is more than enough. In fact, to me, it's a bit too much because it gives me mild stomach cramping, so I just take half a pill, and I'm good to go. You people can't blame the drug when you are overdosing on it. Now, don't get me wrong, this is not a mild laxative (unlike what they imply on their ads, and I do kind of feel cheated about that). It's powerful stuff that will make you evacuate explosively (so to speak), but vomiting and feeling like you are dying is not supposed to happen."

For Constipation "DO NOT TAKE THIS!!! I've been losing weight and trying to tweak my meal plan, but I sometimes don't get enough fiber and then become constipated. I took a single Dulcolax before bed and woke up around 11:30 in extreme pain. I went to the bathroom and had a BM, but immediately after, I got so warm. I sat on the bathroom floor thinking I was going to die. I then proceeded to vomit. I will never take this again."

For Constipation "I have irritable bowel syndrome C&D (constipation/diarrhea). Lately, the constipation has been the culprit. Which caused me to try Dulcolax. I took 2 pills, within hours, the normal cramps started. Around early morning, I still haven't had a BM, but I was vomiting, with no end in sight. I lost 3 pounds within 2 hours from vomiting. Over 14 hours after taking the pills, I finally had a loose BM. I can't wait for it to be over! I'll be starting a probiotic so that I can prevent this."

For Constipation "I took two tablets after dinner and went to sleep around 11:30 pm. At 6 am came around, and I had terrible cramps. I vomited a few times and felt better and went back to sleep. 7 am came, and I had even worse pains and went to the bathroom. After that, I was fine. It did its job but was extremely uncomfortable. I don't recommend taking this if you can't be home for at least 18 hours straight."

For Constipation "I am NEVER taking this brand of lax again. I took one pill around 6 p.m., and around 5:45 a.m., I had the worst cramps ever! I wanted to vomit, and I ran to the bathroom and had such bad diarrhea. This is the second time this has happened with taking only one pill. The 1st time, I was sure I had bad Mexican food, but nope, it's the laxative. The pain was so unbearable! I'd rather be constipated forever than go through that again. I recommend taking Metamucil with 8 oz of water twice a day or fiber supplements. It takes longer for your body to get on track, but it doesn't hurt."

For Constipation "I was having problems with some constipation. I chose Dulcolax because of the word 'GENTLE' on the box. Wrong! I took 1 tablet at night, and the next morning I was in agony! Severe stomach pain, nausea, vomiting, sweats... and finally, in the middle of all this, I managed to have a BM. It is now early evening, and I am still having cramps. I have been in bed all day (only get up to go to the bathroom). I will NEVER go for that 'gentle relief' again!"

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."

For Constipation "So I took 3 pills because I was a dummy, but then I wanted to know how others felt about this product, so I read you need to drink loads of water. I ended up drinking about 10 glasses of water in the 2 hours before I went to bed. I woke up around 1ish having to go badly. Nothing really happened, I sat there sweating like a pig, dry heaving, and wanting to vomit. I had no stomach pains though (possibly from drinking all that water). Then around 4, I was back in the bathroom, and I didn't sweat, dry heave, or anything. It was diarrhea-like, but that I can handle. And I went again around 10:45 am, but now 3 hours later, I feel fine and perfectly cleaned out."

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!"

For Constipation "Took the medicine at 11:30 PM. Decided 2 would be too little since I wanted the full effect, took 3 total followed by water. Woke up at 4:30 in the morning to cold sweats and threw up twice. After cramping in the lower stomach, I went and used the bathroom on and off for 1.5 hours. Next time I am only sticking with 1."

For Constipation "Took the gentle laxative on Thursday at noon, and it's now Saturday at 7:40 am, and I'm still sick to my stomach. It didn't work until around midnight Friday morning when I woke from a dead sleep from the unbearable stomach pain. Finally, after sitting on the pot forever, I went. It was not any better. I was still in horrible amounts of pain. I thought I was done after about an hour on and off and laid down and got a little more sleep until 4 am rolled around and I had to go again 'cause the pain woke me up. This time I went a bunch and also vomited a bit. I NEVER throw up. I will never take this again. It works, but be prepared to feel like you're in hell and question whether it's worth it or not."

For Constipation "As far as easing my severe, almost week-long constipation, it worked within a few hours. I have vomited twice and pooped five times, all within the span of three hours. The stomach pain is terrible. The diarrhea is getting progressively more volatile. If you want to poop, this is the stuff for you. I took two pills. I suggest one for anyone thinking of using it. It definitely works, but the side effects are something you want to experience in the comfort of your own home. Trust me."

For Constipation "Took it for 2 days bowel prep 3 weeks ago, and along with everything else I was taking, it worked. Initial BM was very difficult and painful. Took 2 pills yesterday at about 2:00 pm for constipation. Woke up at 4:00 am sick and vomited several times with terrible pain. Sweating, shivering, and husband found me on the floor of the bathroom at 6:00 am. It took another hour of the worst pain, cramps, and vomiting before I finally went. Then the spigots were open and had explosive, painful diarrhea several more times - sometimes vomiting along with it, but always the terrible pains. It is now over 24 hours since I took the 2 tabs and still cramping every 1/2 hr with some liquid diarrhea. Just trying to keep hydrated. Almost thought about going to ER!!!!!"

For Bowel Preparation "Had to take Dulcolax for a colonoscopy prep. Doctor advised me to take 4 pills at 2:00 pm and at 5 pm to drink the Miralax mixture. My first diarrhea BM was around 6 pm with some slight cramping and sweating. The pain disappeared for the rest of the night, and I thought that was it, not as bad as people say it was. NO! I was so wrong. Woke up around 1 am to excruciating stomach pain that would come in waves of every 4-5 mins, and then on top of that I started feeling nauseous and vomited twice. The pain continued for the rest of the morning."

For Constipation "Never again. Ever. This is probably the 10th time I've taken Dulcolax, and each time is worse than the last. This time I took 2 tablets at 1:30 AM and got woken up at 7:30 AM, feeling extremely sick. Usually, I would lay in bed and wait for it to pass, but not this time. I began to have violent vomiting while my stomach turned upside down! At this point, I was vomiting while trying to not soil myself (which is a very unpleasant experience, especially after first waking up). After BARELY having a bowel movement, I crawled back into bed in the fetal position, hoping it would be over soon. This is when the cramps began. The cramps from this medicine were the worst I've EVER experienced in my life. STAY AWAY FROM DULCOLAX! Stick with Miralax!"

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."

For Constipation "I wish I read the reviews prior to taking this. I took ONE pill at 10 pm and woke up at 5 am in excruciating pain. I was lightheaded and on the verge of vomiting while going to the bathroom. I thought I was sick as opposed to constipated until I read the reviews. It only made me go to the bathroom once, yet the entire day I was on pins and needles because of the feeling in my stomach. It caused me to feel very sleepy, and for the most part I slept. I’m praying the effects will be gone by tomorrow and that I can return to work. I wouldn’t recommend this medication."
