"Worked 2 hours after taking it and removed all of the formed stool before I did the Miralax Gatorade prep. I felt totally fine from the time I took it until 17 hrs later. Woke at 7:30 a.m., before I opened my eyes, my body felt like it was on fire/felt really funny. I remembered the reviews, so I had Emetrol on standby, took some. Then took myself to the toilet, had no poop to evacuate, so I laid on the bathroom floor with ice, felt like I was literally going to die. I was burning up, numb, tingly sweats all over my head/entire body, dizzy, sick, dry heaved twice, so pale I looked like a corpse. After 10 min/pooped some water, it passed. I was so bad I knew I wouldn't make it to the hospital in time before potential death from whatever it was. It had to be Dulcolax."

Bisacodyl "I purchased this as part of a colonoscopy prep. I had issues with diarrhea prior to this and then was constipated for 4 days, so I wasn't sure what to expect. I read the negative reviews and my thought was, 'Why are they complaining? Follow the instructions, drink a quart of water, and wait 12 hours for results?' I have gastroparesis, so my wait was more like 18 hours than 12, but it wasn't explosive, no cramps, and did the job. To add to my potty story, while I was waiting to complete the initial prep, my GI doc called and canceled the procedure. Well, at least I'm cleaned out!"

Bisacodyl "Had bowel issues, so took 2 Dulcolax around 2:45 pm, then drank plenty of water. Also had some carom seeds (ajwain), a herbal remedy with some water, then laid on the bed for 2 hours. Suddenly, I heard growling stomach sounds, so I knew that the tablets were working. Then I had an urge for the toilet and went and sat on it. It was a bit painful, then diarrhea later did go once or twice, but relief not much. Do drink plenty of water, if needed in an emergency, will take it, but after (ajwain) carom seeds, they may just do the job."

Bisacodyl "Ok, so this is my third attempt at getting a colonoscopy. Had bowel issues all my life. First 2 times were with a liquid, first in was a giant jug of chalky white stuff. Had such a bad reaction after one glass. The second one was a powder to put into juice, pop, or Gatorade. Again, a terrible reaction. Made it to the second of three packs before my husband called an ambulance. That was 10 and 5 years ago, respectively. The fear of the prep kept me from trying for a long time. But this time, I got the Dulcolax-2 every 2 hours from 8 am the day before. I was terrified, but I didn't become sick! I had very mild nausea and frequent watery BMs. But no terrible cramps, no vomiting, no need for medical attention! Sorry to everyone who had bad experiences, but this is the prep I will recommend to anyone I know."

"I was prescribed bisacodyl as part of my colonoscopy prep. It came as part of a colonoscopy prep kit. I am not someone who normally has constipation and had never had this drug before. At 2:00 pm, I took the first dose of 2 pills. By 3:30, I was vomiting so hard, I could barely breathe. I looked on the package and online and did not find any cautions about this drug causing vomiting, so I thought maybe my hunger (had already been fasting at that point), coupled with a Tylenol I had taken and the bisacodyl together had been too much for my stomach. Fast forward to 9:00 pm, time for the second dose of 2 pills. By 10:30, I was once again vomiting extremely hard. I began to be worried that the colonoscopy prep was too much for my system and that maybe I was on the verge of having a medical emergency. I was sweating and had chills. It was traumatizing. I will never, never, NEVER take this medicine again."

Bisacodyl "I have IBS-D, so when I did my colonoscopy prep, I was very nervous about taking 4 Dulcolax and then the 64 oz of Miralax solution. I wasn't going to take the 4 pills after reading all these reviews, but I decided to listen to my doctor. I did not experience any of the symptoms everyone is putting on this forum. No cramps or pain, just that feeling of having to go to the bathroom quickly. I ate lightly 2 days before the prep and made sure I had bowel movements on those days. So when it came time for the prep day, I felt that I didn't have a 'load' in my intestines and colon. After 4 pills and 32 oz of Gatorade/Miralax, I was cleaned out. I started taking the second half of Gatorade at 2:30 am, but could only get 1 glass down due to feeling bloated and full, plus I was still going to the bathroom after taking the first half and had to travel 20 miles to get to the hospital. Didn't want to have an accident on the way. Colon was clean."

Bisacodyl "I took 2 tablets at 9 am, as instructed for colonoscopy prep. By 11:30 am, I was in extreme agony with excruciatingly painful abdominal cramps. I sat on the toilet thinking that I had to have a bowel movement, only a tiny amount came out. Cramps continued with a vengeance, as well as nausea and extreme sweating. Finally, after an hour, an explosion of very liquid diarrhea, which has continued every 15 minutes since. It's now been 1 - 1/2 hours since the cramps began, and they seem to be easing slightly. I have to do this again tomorrow according to the instructions on the bowel prep sheet. Can't wait!"

"I used my drugstore's off-brand of bisacodyl since it’s the same but cheaper for my sigmoidoscopy prep. I took one tablet the evening before as directed and woke up in the middle of the night, and still nothing. So I took another tablet and by morning still nothing! There was also an enema involved and still nothing! After that test, my doctor said they will set up my colonoscopy and send me different instructions! Take two Ducolax tablets two days before, and they definitely worked! Woke up at 7 a.m. with extreme pain and spent the day in the bathroom following a few other laxatives. Most uncomfortable I have ever been."

"Yesterday I took only one bisacodyl. I thought I would have to wait a few more hours. No, in 15 minutes, it started a horrible pain, deep pain cramps. Felt like I was dying. Nauseous. I couldn’t even talk or focus. The pain was intense, I couldn’t even sit on the toilet. I tried to be strong before calling 911. I don’t recommend it at all. This product should be out of the market. I still have the pain from yesterday. I threw the package in the trash. I will never take this."

"Oh boy! So I took two 5 mg pills at about 9 pm, then waited. (I wanted to clear out my system due to an uncomfortable abdominal hernia, which is made worse when 'full') Sadly, I'm around 200 lbs; that's why I took 2 instead of 1. I wasn't sure if I'd need 3, but found out that 2 was extremely sufficient! In the morning, nothing happened until around 11:30, when it finally worked and without cramps. (Make sure you take this with no plans or place to go the next day, just in case it hits hard) BUT...I have things to do & places to go today, and what I'm stuck here in my bed with is debilitating nausea. I've had it all morning before the drugs worked, but even after now, I have rotten waves of it. I can stand diarrhea or cramps, but NOT nausea."

"Don't let the bad reviews scare you. For me, it isn't that bad! Before taking them, I wanted to see how quick they would take to work, and once I read the reviews, I was absolutely terrified to take them, expecting the worst pain in my life. I took 2 tablets at 8:00 pm Tuesday night, I had a mild pain in my stomach along with belching and rumbling noises. I woke up at 7 am on Wednesday, expecting to be in pain and be running to the toilet... nothing. I went to work and carried on my day. All day I was expecting it to kick in, but still nothing. I got really fed up that nothing was working, so I took two more at 5 pm and 1 more at 9:30 pm. Before I fell asleep, I had stomach pain, however, it was manageable. I drank lots of water and used a hot water bottle on my stomach. Thursday morning (today), I woke up, and FINALLY they worked, small BM around 3-4 times within an hour, no pain whatsoever. I am not sure if there's more to come, as everyone else in the reviews said that it lasts for a while."

"In my prep for colon camera, I had 2 before bed last night and 2 this morning. It's 7 pm now. Needed the toilet immediately this morning only once or twice, diarrhea city, but the morning pills kicked in at 4 pm today and it was far harder to ignore this time. More action than this morning. Overall, a few cramps here and there, but I've been working in an office all day and not suffered much at all."

"So I'm prepping for this hydro colon cleanse, which is the prep for a colonoscopy. I'm usually constipated and bloated, which is extremely uncomfortable, so getting it out is not the worst. The recommended dosage from my GI doctor is 1 pill a day for 4 days, and I start Reglan 2 days before the procedure (along with the Dulcolax... that will be hell). I took the single pill at about 4:30 pm and went a few hours later. First time wasn't so bad, but this diarrhea... ugh. It is almost 2 am!!! I could not imagine taking more than one pill. I'm guessing they should change the dosage information. I mean, 3 pills??? That is insane!!! One pill does the trick, but I was just wondering how long the effects of 1 pill last."

"Needed to do a bowel prep for LDR Brachytherapy to treat prostate cancer. Directions said to take 2 Dulcolax tablets at noon, followed by a Dulcolax suppository at 8:00 and a Fleet Enema the following morning 3 hrs prior to check-in. Since check-in was at 6:30 AM, started prep at 09:30. Nine hours later, still no BM, used the suppository, waited 45 min, and could have easily waited an hour or more, but had to pee so bad, did manage to have a so-so mostly solid bowel movement. Nothing dramatic like I had 15 years earlier when I used Fleet Phospho-soda for a colonoscopy. The oral Fleet solution had me dashing to the bathroom in an hour and continued for several hours with a very cleansing liquid movement. I did not experience any discomfort such as cramps or nausea, as is so prevalent with others who have commented. I did follow many of the recommendations of others and drank plenty of water before and during the prep."
