Dulcolax (bisacodyl) "Read the reviews beforehand and prepared myself to take it. I had constipation for four days, and nothing was working. Felt uncomfortable, so thought it was worth giving it a try. Drank plenty of water and ate plenty of fruit during the day. Took 1 tablet at 9 pm, and other than a few cramps at 3 am, I slept really well. Did drink loads of water at 3 am as I was sweating a bit, but that went off. Got up at 7 am and welcomed relief. Been 3 times, but no pain or cramping. The key is to drink plenty of water, and eating fruit definitely helped."

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."

Dulcolax (bisacodyl) "I took two Dulcolax pills at approx. 10am 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 2am, I had tummy rumbling, and gas, but really that’s it. BUT at 8am 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 AM-1 PM, 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!!!!"

Dulcolax Laxative (bisacodyl) "WOULD NOT RECOMMEND. I took 3 like the box said (10pm) I took it because I haven't been able to potty for a week. Around 2am I woke to my stomach cramping sooo bad, I get up and go to the bathroom and nothing happened.. 30 mins later I feel even worse so I go back to the bathroom, at this point I'm nauseated and very light headed and once I get to my destination sweat is literally pouring off me like I've been digging holes in the desert with a temp of 115 outside. With all of this going on I went into an anxiety attack which now it's hard to breath.. Thankfully it FINALLY released itself. Next morning I felt like I've been ran over by an 18 wheeler and exhausted beyond belief and shaky.. Definitely not ever takin this again.."

Dulcolax (bisacodyl) "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 duclolax 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 worse 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."

Dulcolax Laxative (bisacodyl) "I took these pills at 9 am and by 1 pm I was overcome with intense stomach cramps, shaking, sweating, and diarrhea. Since 1 pm I’ve had multiple bouts of diarrhea & I’m extremely nauseous. It’s now 6:30 pm 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 & advise others not to use it."

Dulcolax (bisacodyl) "DO NOT! JUST DON’T! Took at 9:00 pm. Woke up at midnight feeling like I was in labor, the stomach cramps were so severe. Then the spasms and convulsions started. 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."

Dulcolax (bisacodyl) "Do not use this product in its liquid form. 1 hr after taking the minimum dose, it happened. Good. Fours hours later, it feels like I have been in hard labour, on the side of the interstate, with dust and sharp glass being blown against me. The pain is causing me to hallucinate. I am dry heaving into shower. Please make this stop. DULCA-DON'T!!"

Dulcolax Laxative (bisacodyl) "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!!"

Dulcolax (bisacodyl) "So the dosage says take 1-3 pills for a single daily dose so I took 3 and prayed for the best because I’m going on a beach trip. I’ve literally been either on the floor in my own vomit or curled up in bed with cramps so bad I want to go to the emergency room. This is TERRIBLE. Don’t buy!"

Dulcolax (bisacodyl) "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. 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."

Dulcolax (bisacodyl) "This past Friday night the 21st of Feb I took one ducolax for constipation as per directions on box which said 1-3 may be taken. It was about 9:00 pm when I took it . By about 10 the pain & 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 its Sunday and its 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 its 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 ."

Dulcolax (bisacodyl) "I hadn't gone for 4 days and decided to try Dulcolax. I am 5'1 and 120lbs. 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 2:00pm and by 6pm 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."

Dulcolax Laxative (bisacodyl) "Ok so I have a funny story about this, I was constipated for like 2 weeks, and so I got this medication dulcolax and I took one in the morning and one in the day. Nothing happened for awhile. So then my boyfriend and I went to a party at the lake. (I know I was an idiot) any way I started to get cramps, unfortunately there are no bathrooms anywhere around there. So I told my BF to take me home but while driving I couldn't keep it in it started seeping out haha so I told him to pull over. Then I got out and pulled my pants down and just let this waterfall of poop pour out my butt. Haha my man just covered his face in disgust but I couldn't care!!! Oh and no toilet paper so I had to use old paper food bags that were in the car. We had to pull over 3 times so I could poop. Finally we get home I shower and go one more time. The experience sucked but after wards I felt so light and free. I felt amazing haha any ways hah thats my story"

Dulcolax (bisacodyl) "This has got to be the worst stuff I have ever taken. I only go to bathroom every 2 or 3 weeks it gets overwhelming and just so bloated I need relief. Well ducolax was the last thing I should have done. The pains in my stomach are so intense I feel like something is seriously wrong. It feels like someone is ringing out your insides. I have been dizzy, sick to my stomach, an over all ill feeling. And super nauseated. I would rather have a bloated stomach. Idk what to do! I have been up and down sitting on bathroom floor and to toilet. Not knowing whether to throw up or poop. Worst ever and very scary. I feel like I was going to pass out. I tried laying down and the pain is too great."

Dulcolax (bisacodyl) "A month ago I had gone three days with no BM and so I took 2 Ducolax pills at bedtime and awoke with a horrific stomach ache in middle of the night and barely a bowel movement next day. It has been a month since that experience and I took a chance the first side effects from Ducolax were a fluke since I have now gone 5 days with no BM. II took 3 pills before bed since 2 weren't effective last month and I just woke up. I can barely breathe so nauseated with a horrific stomach pain and cramping. Too sick to take my dogs outside potty from the nausea and pain. No BM yet, just nauseated with a stomach pain radiating into my back and spine and a little gas. I'm done. This product is awful and NOT gentle. I have been laying here to sick to sleep for a couple hours waiting for the stomach pain to alleviate and so I Googled Ducolax stomach pain. I am surprised how many people suffered like I am. This is my first medicine review but felt I needed to say something."

Dulcolax (bisacodyl) "To be fair, I was a bit concerned after reading the reviews... which I did after taking two tablets. However, I took them at 9 pm. Whilst I woke a couple of times in the night (which is normal for me), nothing happened until 6 am when I had a bit of cramping and a very urgent need to get to the loo. It was at this point I remembered I had put some large bags of cat food and litter in the downstairs toilet. I've not moved 10 kg bags as quickly in my life - I could have given the Scottish caber tossing champions a run for their money. The urgency became a possible emergency situation, and I had visions of writing one of those 'well today was the day I crapped in my kitchen' reviews. Luckily, I made it in time and to not be too graphic, the constipation was very definitely resolved. Felt much better afterwards. Not sure if it's a one-time occurrence or I'm in for more Highland Games later, but so far so good. No sweating or praying for death, so counting as a win!"

Dulcolax (bisacodyl) "Liquid Ducolax seemed to be the fastest - relief at 30 minutes to 6 hours, after all, I do have work tomorrow. I took the recommended dose around 10am. 2 hours, nothing - not even a fart. After waiting three hours total, I took another full dose, it tastes good. 3 o'clock my chicken & dumplings, mashed potatoes and candied carrots were done, we all had dinner. I was starting to get a few rumbles by time my meal was finished, I was happy to know the time was coming & wouldn't be at work for the grand finale. I was finishing my glass of water, stomach flopped, made a loud growling sound & my butt puckered. I ran for the toilet, barley making to let out the most unholy explosion. I swear I just pooped everything I've eaten in the last 2 weeks. I HAD TO FLUSH 2X WHILE STILL GOING. This stuff works, Its been 4 hours since the first attack, I've gone another 6 times. My butt burns from the violent friction caused by the forceful exits. I wish I wouldn't have taken the 2nd dose. Be patient."

Dulcolax (bisacodyl) "Took 2 ... I knew what to expect from previous experience . I love the whole "easy predictable relief the next morning" sales patter . But nothing, NOTHING ! Prepares you for what happens 6-8 hours after taking them . The cramp . That burn . That stagger to the bathroom . That inability to ever trust a fart again. Then it happens . Like a Cape Canaveral launch . You are reintroduced to the xmas dinner from 1992 . You need to buy new clothes because nothing in your wardrobe fits to your shrivelled gollum like carcus anymore. Take when needed. Sleep in the bathroom . And pray to God you have drunk enough fluid to protect your kidneys before the bisacodyl sucks it all into your bowels ."

Dulcolax (bisacodyl) "Female 140 lbs took 2 Dulcolax Tablets at 6:30pm, followed by 3 full glasses of water. Had been constipated for about 5 days prior. Woke up at 6:00am with the feeling of having to have a bowel movement. Passed a lot of liquid /semi soft bowel motions. No cramps, no feeling of illness. Was petrified by all of the other reviews, but thinking drinking water after taking the pills helped. No side effects the next day."

Dulcolax Laxative (bisacodyl) "Omg the stories of the others that experienced this dreadful laxative are hilarious but at the same time I feel their pain. They changed something with the Dulcolax pink. It never used to cause the nausea and stomach pains that it does now. I have to look into a new laxative as I can’t deal with this when I have to take it often due to constipation. I wish they hadn’t changed the make up of this because it never use to cause the pain and nausea dry heaving like it does now. Seriously I wish someone at Dulcolax would read these reviews."

Dulcolax (bisacodyl) "Look, it is a laxative. Yes, it will cause pain. It says it on the box. TAKE IT WITH LOTS OF WATER! Seriously! I cannot reiterate this enough! I have IBD and sometimes I get constipated. This really helps. Yes the pain can be uncomfortable (to some unbearable), but take some anti-inflammatories and you'll be fine. The cramps are a signal that the meds are working like they are supposed to. Trust me as someone that has a bowel disorder and has had 5 colonoscopies before the age of 30, this works. It JUST TAKES TIME! I know poo pain. I know poo cramps. I know the pain! It sucks! It really does! Yet, it is effective. There are some people that may not be able to handle it, but others can. Don't be scared and understand it is good for a reason."

Dulcolax (bisacodyl) "It works, but do not take three! I woke up out of dead sleep three hours after ingesting with SEVERE pain. I have irritable bowel syndrome with internal hemorrhoids so constipation happens often and always hurts. I took three thinking because I'm almost never regular and my last movement was over a week ago three would probably work best. I ended up pooping, but also had a heavy vomiting episode at the same time. Take two at most, do not take three!"
