Clenpiq and Vomiting: What Users Say

For Bowel Preparation "For 2-3 days prior to prep day, I ate very low fiber foods. Prep day, I did liquids. At 5pm, I drank the first bottle. It was okay and I sucked a lifesaver while I drank it. I used a straw and was able to finish it fairly easily. I then drank 24 ounces of liquid. About an hour later, I got a headache and was nauseous. Then, I began going to the bathroom regularly. From about 7 p.m. to midnight, I was running to the bathroom and I did dry heave a bunch. But by midnight, I was pooping totally clear. I was so nauseous that I decided, since I was totally clear, that I was not going to take the second bottle. I decided not to tell the doctor I only did one bottle of prep since I was still pooping totally clear. I am 5 feet and 116 pounds, and the doctor said I was 100 percent clean and did a perfect job. I am not saying everyone should only drink one bottle, but if you feel you absolutely cannot continue AND you are pooping clear, I can say it worked for me!!!"

For Bowel Preparation "I have had several colonoscopies and various preps over the years. This one is the easiest in terms of the amount of liquid required, however, after an hour or so after the second bottle, the vomiting began. The taste is not great, but since the bottle is so small, it is manageable. The bowel movements started about 45 minutes after the first bottle. I had no issues with cramping, etc. I also didn’t need to spend every waking moment in the bathroom, and the prep was effective (the doctor said the cleanout was excellent). I plan to request this prep for the next procedure (for me, it’s every 2 years). I usually do not post comments, etc., however, I did research this prep prior to utilizing it, and based on the reviews here I was apprehensive about it. It honestly is not as bad as some of the reviews indicate, so I wanted to share my experience in the hopes it will help relieve others' anxiety about the prep."

For Bowel Preparation "Just had a colonoscopy screening this morning after Clenpiq prep. I hope this encourages others with anxiety about colonoscopy prep. I was terrified of all the possible negative side effects - headache, cramping, nausea, and vomiting, and not being cleaned out after all of that. I have a sensitive stomach and don't drink a large volume of fluids. Ate a low-fiber diet for 2 days prior to prep day, and I took Zofran (anti-nausea medicine) 30 min before each prep dose. I easily drank lots of fluids yesterday - and I am NOT a chugger - and I was not hungry. My nurse said I could sip the prep - better to take 30 minutes to finish it than drink too fast and risk nausea/vomiting. It didn't taste BAD, just very sweet. The prep resulted in clear, pale yellow elimination with no cramping, extreme urgency, or other side effects. I took one Clenpiq dose at 3pm and one at 9pm yesterday. My procedure was at 7:30am today. I am SO thankful I did it - screenings are so important! I will choose Clenpiq again!"

For Bowel Preparation "For bowel preparation: This is definitely NOT a one-size-fits-all. I weigh under 115 lbs (5'1). This was the most barbaric and traumatizing prep I’ve ever done. I would not recommend it to anyone, ever, for any reason! Severe cramping, vomiting simultaneously while cleansing the colon, shaking, trouble breathing, numbness in legs and arms. Absolutely terrifying. I thought it was going to be the end of me, alone on my bathroom floor! I was given the same quantity/prescription that a 200-400 lb person would receive. This stuff is toxic! Never again. The prep caused serious internal inflammation."

For Bowel Preparation "I am 80 plus years old. I have had several colonoscopy preps. I have always had a nauseous stomach. This is the easiest prep I have ever done. The others make you drink the prep with a gallon of water, which I would immediately vomit up, and they tasted horrible! With Clenpiq, one x 2 bottles and a glass of liquid every hour for 5 hours is a piece of cake. Yes, it is sweet, but so are the others. It worked for me."

For Bowel Preparation "This stuff is awesome compared to the nightmare preps I've had in the past! Easy to drink, no nausea or vomiting, no cramping. I was so surprised considering I have only had violent reactions to laxatives in the past. The taste is salty and sweet and kind of lingers in your mouth, but it was a small amount to drink. I just chugged it down without an issue and followed with a full glass of water. I was pleasantly surprised at how easy."

For Bowel Preparation "I have used every bowel prep on the market, and I could tolerate none of them. Clenpiq was actually the first prep where I could complete both doses with no vomiting or gagging. I was shocked at how much better this prep was compared to the standards. Easier to get down, worked immediately. Second dose a little harder, but I was exhausted by that time. Have your doctor give you an anti-nausea drug and take it 1/2 hour before each dose. Take your time, slug a dose, and chase it with a beverage of choice. The volume is so much smaller and quicker to get down. It is not that bad. Flavor not awful, I was pleasantly surprised. I would highly recommend."

For Bowel Preparation "CLENPIQ is by far the worst medication I have ever taken! The taste is pungent, acidic, and still penetrable while holding my nose! I could not swallow once without gagging! Then there is an aftertaste that lingers for many hours. It feels like it has infiltrated your gums, tongue, and mucous membranes. The only decent thing I have to say is that it was effective. With all the strides in medicine that have been made, and colonoscopy being a routine procedure, there must be something better than this product. I don't think any person should be subjected to this, ever! I had a colonoscopy 10-15 years ago and the prep was no big deal. If it were like this experience, I may not have had a second colonoscopy. I have been through surgeries, births, other medical procedures, and many, many medications. Some have been painful or uncomfortable, but I would choose any of them over this! If this is prescribed for you, please ask for something more pleasant!"

For Bowel Preparation "Horrifyingly bad! I never had such terrible cramping, even while giving birth to two children naturally. On top of that, I had explosive diarrhea and vomiting all at the same time. I truly felt like I was going to die from the trauma that was unleashed on my body. The doctor said to go to the ER, but how do you get to the ER when you are expelling from both sides of your body and doubled over from cramps? This all occurred after ingesting the first bottle. Needless to say, I never took the second. I won't be using it again. Ever. I would give this a 0 rating if they allowed."

For Bowel Preparation "Took first dose at 6 pm. Started bowel movements about an hour later. Done by 10:30. Woke up at 4 am for second dose. Half an hour later, felt nauseous. Another half an hour and vomited everywhere. Vomited three times in an hour. Must have vomited it all out because it did not do its intended purpose. Felt like I was so ill for five hours. Had to cancel the procedure because I wasn’t cleared out and nauseous."

For Bowel Preparation "I've had probably 7 colonoscopies since 1995, and this CLENPIQ prep is BY FAR the best-tasting prep I've ever had (aside from the pills, which is still my number 1, but they won't give them out anymore). It sort of tastes like five-hour energy's in the little red bottle. I always have major anxiety and basically gag before I even taste the prep because I already know in my head what it's going to taste like, and I have a really hard time getting it down. But the CLENPIQ was seriously super easy to get down. I had the cranberry flavor. I never understood, with all these advances in medicine, why they couldn't make a better-tasting prep! FINALLY! My doctor gave me this from his office, so I don't know what the cost is."

For Bowel Preparation "I would definitely do this prep again if they don't come up with something even better by my next procedure. No cramping, no vomiting, no feeling like a lot of liquid sitting in my stomach. The taste was not good but tolerable (drank it down and sucked on a lemon drop to get the taste out of my mouth.) I read a lot of reviews on preps, and I think the low residue diet three days before helped a whole lot. I wasn't sure it would clean me out because I didn't have near the BMs like when taking other preps, but I was cleaned out. No warning sign for bathroom time, muscles seemed to just open up. I would try to up my electrolyte drinks next time because they had to give me some, although I drank lots of liquids (for someone who doesn't like water.) I had read so many negative comments on this prep, but it sounds like it just depends on the individual."

For Bowel Preparation "Did not work for me. After the first dose, violent cramping, wicked headache, nausea, vomiting, chills. Could not take the second dose and had to cancel the procedure due to incomplete cleansing of the bowel. All in all, a miserable day of clear liquid diet and attempted cleansing for nothing."

For Bowel Preparation "First dose Clenpiq: stomach pain and nauseous; visits to the bathroom were no more than 3. Second dose: after 15 minutes of the intake, felt nauseous and like in seconds and on my way to the bathroom, I vomited all of it. I don’t think I will be okay to have my colonoscopy and will never ever use this product again."

For Bowel Preparation "Clenpiq is a cranberry-flavored liquid that you drink directly from the bottle. It is very sickeningly sweet and viscous, and I kept having to drink water in between as a chaser. Within an hour, I started pooping, which was fine. Then, after 4 hours, I started getting chills, then felt hot, then felt like I was going to pass out! Knowing that I would have to take another 5 oz dose at 11 PM didn't help. I stared at the bottle at 11:05 PM and took a few swallows of Clenpiq, then immediately started vomiting white foam. My husband kept encouraging me to finish the bottle so that I would be cleaned out. I tried a few more swallows and again started vomiting. There was no way that I would be able to drink that second bottle! In my case, I think that one bottle was sufficient for me because I had been going to the bathroom quite often, and Clenpiq was very potent for my system. I'm not sure that I will ever undergo another colonoscopy because the prepping process is a terrible experience!"

For Bowel Preparation "Unfortunately, I did not have a good experience with Clenpiq. The first bottle went down fine, as well as all of the water required immediately afterwards. But when I drank the second bottle at 5 a.m. the next morning, I was only able to keep the contents in my stomach for 5 minutes before experiencing severe nausea and vomiting. Unable to keep any liquids down despite continued attempts over the next 2 hours, I experienced dry mouth and skin as I dehydrated. My colonoscopy had to be canceled due to inability to complete prep."

For Bowel Preparation "First, I will confirm that I followed all my doctor's instructions precisely. After the first dose of Clenpiq at 5 pm, I had a terrible headache. Forty minutes after taking the second dose at 10 pm, the nausea and vomiting started. From 10:40 pm to 3:36 pm, I was sitting on the toilet throwing up in the trash can. I was mostly, but not completely, cleaned out. The doctor wrote on the report that the colonoscopy was difficult because there was 'retained stool.' That was no surprise since I'm sure I puked up most of the second dose."

For Bowel Preparation "I gave it a 10 out of 10. Best bowel prep I have used! There are 2 small bottles of super sweet liquid. Took it in sips with lots of other water/liquids. Not hard at all (considering I had vomited up prior high-volume preps). Not a fan of sweet drinks, so mostly drank chicken 'not your average bouillon' in between, with water, tea, etc. One dose in the evening, the other early the morning of. Easy as can be. Rate 10."

For Bowel Preparation "Ok, so this was my fourth colonoscopy, and while different for each of us, I have to say I will be mildly inconvenienced by this in order to avoid getting colon cancer. That is what gets you through it! I have had different preps, and I liked this the best, and by best, everything is relative as they are all disgusting! But the volume of this is much lower. It doesn't taste like cranberry but instead like a sweet solution of something nasty. I gave it 9/10 only because I got very nauseous once and threw up, but I was very cleaned out for my procedure. And it also dehydrated me terribly, maybe because I didn't finish all of the required water, but I was drinking like a fish for a week after."

For Bowel Preparation "One hour after drinking the first bottle of Clenpiq, I went to the bathroom and vomited for over an hour constantly. Bowels didn’t move for another hour or so. I was freezing and wrapped a blanket around me. Next, the horrible sweats started. My hair was soaked. I was so miserable I couldn’t get comfortable. I started shaking, and I had tingling in my feet and hands. I could barely speak because my teeth were chattering. I asked my husband to stay close because I was really scared and, at one point, thought I might be having a stroke because my left leg felt numb. He handed me the phone, and I called the doctor on call. He said I would be fine and side effects like this are rare, and he would cancel my colonoscopy. After starting to evacuate my bowels, the horrible side effects started to ease. I did some more vomiting and finally was able to lay down for a bit. It’s 12:40 in the morning, and I’m still pooing, feel weak, have a headache, and can’t wait to never use Clenpiq again."

For Bowel Preparation "Awful experience. After drinking the first bottle, I vomited within 20 mins nonstop until it was completely out of my system. I did not have a bowel movement. I was nauseous and felt awful the rest of the night. I tried again in the morning, this time drinking it slowly, but vomited it up. Clenpiq is expensive and not worth it. If I had taken it earlier instead of 6 pm, maybe I would have had enough time to recuperate to switch to MiraLax. Ugh, such a bummer to have to reschedule and go through the prep again. I wish I had read reviews on it before taking it."

For Bowel Preparation "First dose worked about 45 minutes after taking it. Had to go a few times throughout the evening, but it was manageable. Went to sleep and woke up at 3 am with chills, a terrible urge to vomit, spent the last hour in the bathroom, couldn’t get off the toilet, it was a terrible 1 hour. It’s now just after 4 am, just took the second dose. I feel much better, but I’m dreading the effects. I’m hoping everything is good for my 8 am colonoscopy. I don’t ever want to do this again!"

For Bowel Preparation "Worst experience ever. Followed instructions to a tee, ate/drank only clear liquids. Drink plus water made me completely want to vomit. Started peak elimination about the time for my procedure. In and out of the bathroom in Johnny with IV. Excruciating headache still hours after the procedure, and my rectum is bleeding and so inflamed it feels like it’s on fire. And I’m still eliminating. I cannot believe they charge what they do for this poison. This was my third colonoscopy and my worst experience. Why do doctors prescribe this? So they can keep you coming back for more $$$$!!! Do not take this garbage!"
