For Constipation "I took these pills at 9 a.m., and by 1 p.m. I was overcome with intense stomach cramps, shaking, sweating, and diarrhea. Since 1 p.m. I’ve had multiple bouts of diarrhea, and I’m extremely nauseous. It’s now 6:30 p.m., and I’m literally afraid to leave my bedroom for fear I may not make it to the bathroom. Constipation is better than this. I will be throwing this product in the trash and advise others not to use it."

For Constipation "OMG, I took two, thinking, oh, I will be able to get my bowels to start working. 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 "Took two Dulcolax before bed because I had been constipated for a few days. All good until about 7 am the next morning when I woke up with the WORST pain I have ever had. I would like to mention I birthed two babies over 9 lbs :) this pain was way worse. I threw up, had sweat pouring off my body in agony. End result, it finally worked, but was not worth the severe stomach cramps. I truly thought I was going to pass out or die. Don't take it - save yourself :)"

For Constipation "I used this after an appendectomy to counter the constipation from that and pain meds. Took two and had no adverse reactions and a good BM 12 hours later. Things were still not quite back to normal, so took 2 more after a couple of days. Within 2 hours or less, was overcome with intense stomach cramps. Another BM at that point, but no relief from the cramps. Started to feel sweaty and pale, and it hurt so bad I was afraid it was an adverse effect from the appendectomy, so called 911. Normal vitals, so was advised that laxatives can have this extreme effect. Constipation is way better than this."

For Constipation "The medication was very effective, however, the excruciating pain I experienced while taking the medication was not a fun experience. I took two tablets at 9:00 a.m. Two hours passed, and I didn't feel anything. Then it hit just about noon, and I started getting terrible stomach cramps. If you are a first-time user, take one."

For Constipation "I have been battling constipation for a week now and had finally given in and bought Dulcolax laxative tablets (worst mistake ever). I took one tablet at 9 pm, woke up in a cold sweat at 2 am, and experienced stomach cramps (with the urge to go but couldn't) and horrendous vomiting. Finally settled back into bed around 3:30 am. I am now up again at 8 am, back in the bathroom with the worst case of diarrhea and stomach cramps. Product is somewhat effective but plan to take it on a Friday night with no other weekend plans!"

For Constipation "Well, I’ve had really bad, painful constipation for days now. I was able to go a little, but I hate to admit I mostly pushed (which I know you're not supposed to do, but I was desperate!). Anyway, I got my fiancé to go get the Dulcolax pink. Took it in the afternoon, and nothing happened. Figured it wouldn’t work. I read all the reviews and was horrified, thought I was going to die with these terrible cramps that people said would come my way. Woke up a couple of times through the night with light cramps, but nothing. Got up at 8:30 a.m. because holy moly, I gotta poop. Cramps were there and wow! Helped me out so much like you wouldn’t believe. Yes, my stomach is sore and I’m nauseous, but the cramps really aren’t bad at all. This drug is different for everyone, but I do recommend it. Drink lots and lots of water after taking it! I saw a review saying you won’t get the bad cramps if you drink like 10 glasses of water, so I did, and I’m fine!"

For Constipation "Awful and not worth it. Intense stomach cramps and nausea. More came out of my mouth than my behind. Worst night of my life. Similar to all the other reviews. Do not use this product, it should be taken off the market."

For Constipation "DO NOT TAKE. I’ve taken this once before around 9 pm and had woken up around midnight with severe stomach pain and cramps. Took hours for them to go away, but they finally did when I was able to explode like a water hose out of my butthole. A few months later (last night), I decided to take one since I’ve been constipated and bloated for 3 days. WRONG. I couldn’t even sleep from the amount of gurgling I felt in my stomach all night. Finally decided to get up and try to go do the deed. Nothing but extreme abdominal pain again. To the point where I’m doing breath work and rocking back and forth like I’m in labor. My upper stomach is bubbling, and my lower stomach feels like I have the worst period cramps of my life. Seriously feels like my lower abdomen was cut open. Actively trying to Google search 'how do I get laxative cramps to stop' and can’t find anything besides other people's horrid experiences with Dulcolax. Not worth the pain."

For Constipation "Oh. My. Lord. I have used Senokot in the past to help relieve bouts of constipation and never had any problems. Today, I had to get Dulcolax as Tesco was out of Senokot. I took two around 6:30 pm, it is now 12 am, and I have been sat on the toilet for near on 1.5 hours, never had stomach cramps like it. I’ve been having to throw up in the sink next to me. I’m that scared of moving, as I finally had a very violent BM, but still feels like the worst is yet to come. Will never, ever take again, and the box is already in the bin."
