"Drink plenty of water!! You have to be very well hydrated with this laxative, otherwise, you will experience severe cramping, nausea, and vomiting. My very first time taking it, maybe 4 years ago, I thought I would finish my life in my bathroom. This time, I read reviews, and I hydrated with fruit and water all day before taking it at 6:30 PM. Because I hadn’t gone in almost 7 days, it didn’t kick in until 4:30 PM the next day. I still had some cramping, but not nearly as painful as my first experience."

"If you want to experience your guts evacuating your butt, this is the medicine for you. 100% effective at relieving constipation. But in my experience, in no way worth the agony I encountered through the night, as well as a massive bout of vomiting. I am good when it comes to pain, and this was like nothing I have ever encountered. I would rather have a month of Sundays' worth of constipation than take this again."

"I normally take Miralax when I'm constipated because it just softens my bowels and regulates me afterwards, but I couldn't find any in the store, so I bought Dulcolax for the first time. Well, I took two tablets at 11:30 at night, thinking I would wake up late in the morning and use the bathroom-no problem. No. At 4:30 AM, I woke up and felt like someone was punching me in the stomach, and I thought I was going to vomit. I then had diarrhea, and then the 'peeing from my butt' experience."

"I am on prescription opiate pain medication, which makes me constipated on a regular basis. I have tried every laxative on the market aside from enemas, and this is the ONLY one that relieves me. Yes, I do experience cramping a few minutes before 'it's time to go,' but it definitely does its job every time."

"I've been constipated for over a week. A friend recommended Dulcolax. I took two tablets with several glasses of water, and about 2 to 3 hours later, I felt a normal urge to go to the bathroom and did. I've read reviews on here about terrible cramps. I had none. Will use again, if needed. Maybe drinking a lot of water helps."

"I had not had a bowel movement for a couple of days, so I decided to try Dulcolax. I took 2 tabs around 6 PM and went on with my usual routine, which included exercise, lots of water, and a bath. I went to bed around 9 PM and woke at 12:30 AM with intense stomach cramps. The pain was almost equivalent to the time I gave birth with no pain meds. This pain went on for a couple of hours. I was sweaty and laying on the bathroom floor naked when my husband found me. He helped me to the toilet where I finally went to the bathroom. It was pure liquid. This went on for several minutes. I also ended up throwing up several times. I was so sick I had to call into work. After 24 hours, I was still weak and could not eat much. I will NEVER take this product again!!!"

"Oh, this product works alright. I took 2 around 11 a.m., and right now it's 3:45 in the morning, and I am experiencing the worst stomach pain ever. Seriously, if you're going to use this, just take one."

"Okay, so I did the worst possible thing and not read the packaging. Thought they were an instant fix, not hours, so when after half an hour I took the first one and nothing, I took another two. And then after an hour, another two. I repeat: READ THE PACKAGING. Two hours later, I had the worst diarrhea of my life visiting a sick relative. Since then, which was 7 hours ago, I haven't been able to get up off the toilet. These work, but please don't be an absolute idiot like I was and take that many. There is nothing left to come out of me, but it's still coming. It feels like Satan is trying to rip my heart out through my anus."

"Had been constipated for the past 5 days and was tired of feeling like crap (no pun intended), so I decided to give this a try. I'll do a little more research next time, but I'm quite happy to say that it worked. Took 2 pills at 12:15 PM and had bowel movements at 4:15, 5:15, and 6:15, like clockwork. I believe what you do before and after you take the pills definitely affects how you will feel when it hits you. I had veggies, a fiber bar, and an energy drink for breakfast, two fiber bars for lunch, and drank a liter of water when I got home. If your body isn't ready, then you can expect to feel terrible because your digestive tract has nothing else to pull from. I'm a 5'4'', 125 lb woman and didn't have any horrendous side effects."

"Took 2 Dulcolax tablets at 8pm for relief. Got no relief at all. Relief I actually survived the ordeal. By 3am I thought I was going to vomit. Cramps so incredibly strong. Nothing happened. Laid on the bathroom floor cover in cold sweat. Could not move, even to sit on the toilet was risky as I was extremely faint and lightheaded. Finally had a release. Thought my whole insides ended outside. Thought that had to be all, but no, another 3 hours of incredible pain, cramps and sweats. Ended up sleeping on bathroom floor to cool down. Two days later and I can’t seem to eat without getting massive pain in my stomach area. Have a recurring cramping nearly every 30 minutes that has me hunched over in pain. If doesn’t stop tomorrow will need to see doctor. Hopefully not twisted bowel due to tablets."

"I have suffered with chronic constipation my entire life..I have had scope tests, tried all the things I read about and what the doctor says, but after awhile everything stops working and I have to take a store bought laxative..I bought Dulcolax for women because it said GENTLE overnight dependable relief..what a crock..this product almost killed me..at 11 pm I took 2 little pills..by 2 am the cramps started, by 4 am the pain was getting severe and I was up every 20 minutes..by 6 am I was vomiting and the pain was excruciating, by 8 am I had to call for my husband because I was sweating profusely, my skin felt clammy, my legs were tingling and my head started to spin like I was going to pass out. The pain just kept getting worse. I was a full 36 hours in sheer agony. It did move my bowels, but at this cost, it is not worth it. I actually thought at one point that I was going to die..this product is dangerous and should not be sold to anyone."

"Do not take this!!! Was recommended to me when I called the nurse after delivering baby because the pain meds they gave me had me severely constipated. Was finally home and healing from all the tearing three days after baby, but no bowel movement and getting desperate. Did one dulcolax suppository and felt like nothing was happening when all of a sudden it started to rock and roll. Talk about contractions! I was convulsing and going into full body curls and spasms. My body took over and I had zero control! Way worse than my delivery just days before and I was severely traumatizing the perenium all over again. Felt like I was ripping everything a second time. I can’t believe this was recommended to me and I can’t believe this is on the market. Lasted hours and I was almost about to call emergency because I thought this was a severe and unexpected reaction, but decided to wait because I couldn’t make it to the phone anyway. It was violent and messy to say the least. Scary stuff."

"OMG. Save yourself. Do the enema. Holy smokes. My diet was off and I knew it. After 3rd day I figured I better do something. My abdomen was huge. I'm not a big guy & don't take meds of any kind willingly, so when it said I could take 1 to 3 of these tiny time bombs I opted for 1. ONE. The cramps started about 6 hours later. Got me out of bed. I spent the next 2 hours doubled over in pain so high I vomited. No joke! Both figuratively and truthfully. No BM yet. I figured if it hurt that bad I must have a real problem. bowel obstruction? Cancer? I thought I was dying. I lay on the bathroom floor in a cold sweat only getting up to vomit or try to crap. Once it finally happened, it took 3 days to be over. My body kept trying to turn my anus inside out. Poor butt bled for 24 hours. My stomach still isn't right at 4 days later. Save your bootie! Don't do it! Anything but ducolax... that part on the box that says "Gentle dependable relief" there ain't nothing GENTLE about it!! POOPERS BEWARE!!"

"I haven't had a bowel movement in about 8 or 9 days. I took two pills around midnight and woke up around 5 a.m. to a bowel movement. It helped my constipation. I went back to sleep and woke up about 7 a.m. to an immediate bowel movement. It is now 7:45 a.m., and hopefully this is over. Works great though."

"Took 5 mg of Dulcolax going to bed at 10 PM. Woke at 4 with excruciating abdominal cramps, then started having heart palpitations, sweats, nausea, worse pain than childbirth... then I fainted! Woke up on the tiled bathroom floor with 4 children looking at me thinking I was dead... have a head injury from the bang on the tiled floor, soiled myself 'cause I hadn't the energy to lift myself to the toilet seat... profuse diarrhea for 30 minutes... bed-ridden for 6 hours after the faint... NEVER again will I take this medicine... on the bottle, it says 'for gentle relief of constipation'... nothing could be further from the truth. I'm actually traumatized."

"Had taken Dulcolax in the past with moderate luck and no side effects... until now. I took it last night because I ran out of Miralax, which I have to take every night for my IBS-C. As with other reviewers, I am in some of the worst pain of my life, AND in the past, I have been carted off to the ER in an ambulance twice. I am having bowel movements irregularly with increasing pain, even though I am expelling waste. I feel nauseated to the point where I think I might throw up or pass out. I have broken into a feverish sweat and cannot stop shaking. To address other reviewers: yes, I drank the water and no, it didn’t help; and I have taken at least 3 other laxatives before with no severe pain, so the pain is NOT necessary to sit through to have a bowel movement. I say sit, but I have no strength to keep myself in any position but lying on the floor due to the pain. I will return to my trusted Miralax. This medicine is poison and should not be sold to anyone for any reason."

"Using these for a while so learned the best ways around the cramps, you've probably read on here and pooped yourself (you wish). I can't poop for about 5-7 days sometimes so I take them depending on the severity of constipation, if I haven't been for 5+ days I take one before bed and go fine in the morning. If I've not been for 3/4 days I only take half a tablet and go fine. If take a whole one with no severe constipation I've noticed that the poop is more runny and the cramps heavier. I will take one before bed and set an alarm to take a painkiller at around 5am to prevent the cramps, it works!! No cramping= pleasant pooping. I've been taking these once or twice a month for over a year and they do work, I suggest only half of tablet if the constipation is only 2/3 days old and the full 1 for anything over, but don't forget the painkillers for better experience. Happy pooping!"

"I take Dulcolax when I feel like my bowel system is playing up. Or to avoid serious constipation. I usually take it with a glass of water. But it doesn't help with the cramps, ever. It wakes me up at 6 am if 1 pill is taken between 10 p.m. to 11 p.m. Cramps are too bad, but the relief is great. Works almost every time for me."

"For all you "horrible cramps, worst pain ever, bad drug" people. You had a blocked Bowel. The directions warn using it with that, yet the only way I've ever known I had a blocked bowel was when I was writhing in agony. So unless you have your own X-ray at home, I'm not sure how one would know. Anyways, it's not the laxative to blame, it's your condition. Remember why you took it? People always confuse causality. "I took X, then this happened. X is bad and at fault." It's more likely you would have gone through the same experience at a later time, and the laxative just brought it on sooner. I'm pretty sure stimulant laxatives increase the pain and severity of cramps, which is why it's warned for. Yet a blocked bowel is hell. Been there."

"I use this awful drug because I have a paralyzed bowel from a tethered spinal cord. I WOULD NOT RECOMMEND THIS TO ANYONE WHO IS EXPERIENCING JUST OCCASIONAL CONSTIPATION. This stuff is intense and if you don't feel like cancelling all plans for the day and being on the toilet for hours, then this ain't it chief. Extreme cramping, vomiting, fainting, you name it. I'm the type of person that goes hard and takes the full dose (3 pills). Let me tell you don't do that unless you want to be writhing on the ground contemplating if you are dying. Over all the only positive thing about this medication is after hours of intense pain, all hell breaks loose, you see the sunrise on the horizon, a choir of angels starts to sing, and you feel 20 pounds lighter. You get the picture."

"Please for the love of GOD, do not take Dulcolax. It’s 3 am and the only thing keeping me somewhat sane is reading these comments and knowing that I’m not the only one who is going thru this nightmare. The word GENTLE is complete and utter BULL. I took 2 pills around 9pm tonight, and at MIDNIGHT I woke up to the worst full stomach cramps ever. The diarrhea has been pretty much nonstop and so, so painful. I wish I would’ve found this page before taking these pills. They are in the trash and I pray that this will end soon."

"Lord, have mercy. I don't wish this feeling on nobody! I took two tablets at bedtime around 2:30am, woke up to stomach cramps, cold sweat, shaking, nauseated, and feeling faint! I've been on the toilet for an hour, rocking back and forth, praying. Oh my God, I feel like I'm about to die! I will NEVER in my life take another one. I'm so weak and in pain! I feel terrible and am thinking about going to the hospital! I got a trash can in front of me, throwing up and using the bathroom. Never again!"

"Omg y’all. This stuff is seriously awful!! I took two pills at 8:30pm. Thank god I didn’t take 3. At 3:30 am, I woke up with terrible nausea and a bubbly stomach. I laid there and tossed and turned for a little bit. I finally got up, went down stairs so I didn’t wake up my family but horror sounds of poop shooting in the toilet. I was sweating, stomach cramped up and I couldn’t tell if I had to poop or throw up or both at the same time. It’s now 7:50am, I still have bad diarrhea. I’ll be canceling some stuff today because I’ll need to be by a bathroom at all times. Lord have mercy. I’ll stick with miralax next time. Read reviews before taking this! I wish I did!!"
