For Bowel Preparation "I will not use this product again. First dose of Plenvu was unbearable, took me an hour to finish and thought I would vomit afterwards. Second dose just as bad, but so much nausea I’m unable to finish the entire jar. I get the reason we all elect to have the colonoscopy, but there had to be a better way! They can send a man to the moon, can’t they make this process better? Just hope I get through the night without throwing up."

For Bowel Preparation "I gave this a 10 for effectiveness because it is unbelievably effective and powerful. That is the only good thing I can say. I have so far used the first part of this prep. Within less than 10 minutes, I was running to the bathroom. Sat for over an hour before I could safely get up. The cramps and stomach pain were terrible. The taste is horrible. I used a straw to try to avoid the taste and still gagged with every drink. Still trying not to throw up. I would never recommend this stuff."

For Bowel Preparation "I'm 26, this is my 1st colonoscopy. I have nothing to compare the prep to. Dose 1 is FOUL. Gag with every sip, even when chased with ice water. Projectile vomit twice, one halfway and one when done. I had to lay down and shut my eyes because of the nausea. I had a migraine all day, so that probably contributed. I was bloated, but did not have a BM until I started dose 2. Whoever suggested a hot bath is a SAINT because I felt so awful after dose 1. I didn't know how to cope, the bath helps. Dose 2 is much more tolerable. Less powder, less thick. Flavor is better. Still very salty and needs an ice water chaser. The liquid BMs have been really frequent since starting dose 2. It's been hard to drink in between. However, there is no abdominal pain involved. It is amazing compared to the awful pain I have had that has driven me to get this done. All in all, I was scared to death about dose 2 because of how awful dose 1 was. But that made dose 2 seem kinder."

For Bowel Preparation "This was the most disgusting thing I have ever drank in my life. I've had 3 colonoscopies with no problem before, but I could barely drink the first dose, and although the second one tasted a teeny bit better, I threw everything up and had to have an enema instead. If I had known this beforehand, I never would have used it. It was really gross."

For Bowel Preparation "Ok, it's 2:30 a.m., and I am working on part 2 of Plenvu bowel prep. So, here is my experience. Part 1 tastes awful. You should never make a medication drink taste like mango! NEVER! But I got it down. Was on the pot for 4 hours. Woke up at 2 a.m. for part 2. Taste is a little better: fruit punch. Still hard to get down. Will update when I am finished. Lol. Ok, get over halfway done with part 2 and threw it all up. Still feel nauseous."

For Bowel Preparation "I would highly recommend this prep, which I chose for my first colonoscopy. It's the lowest volume option (less to drink), and while I suspect they all taste horrible, I was able to drink this without issue (kept it cold, used a straw to minimize contact with taste buds, and sipped water to clear the aftertaste immediately). I get an upset stomach easily but didn't experience that with this prep. It was effective but with no cramping or nausea, and I didn't have to get up in the middle of the night. I did scale back on certain foods a few days prior, however, (red meat, anything with skin (onions, grapes, etc.). Doc said prep was excellent."

For Bowel Preparation "I used Plenvu yesterday evening to prep for a colonoscopy this a.m. The Plenvu prep was simple, and I was cleaned out for my colonoscopy, which was the objective. The first stage at 6 pm was 16 oz of powder mixed with water to be completed in 30 min., followed by 16 oz of water in 30 minutes. I recommend cold water and a straw. I started passing liquid stool upon finishing the plain water and was to the bathroom 4-5 times. At midnight, I began the 2nd half of the prep, which was 2 packets mixed with 16 oz of water in 30 minutes, followed by 16 oz of water in 30 minutes. I had a need to get to the bathroom before finishing the plain water. I had liquid stools for 2 hours and was clear when my stools stopped. I describe the prep as “harsh” and effective, as a successful prep typically is. I was nauseated at times and took a Zofran to ease the nausea. I had an insatiable thirst before going to sleep at 2 am and drank ice water. No prep is pleasant, but this prep worked."

For Bowel Preparation "Just carefully follow your doctor's instructions on how to take this, and you will be fine. The taste was not great but bearable. I just had some other drink ready to chase it down with. I also used a straw to help drink it. Be sure to stay very close to the toilet about 30 minutes later. It took me about 3 to 4 hours to finally feel like it was through. Be sure to wear something old and easy to get off in case of accidents. Even though I was taking the second dose at 3:00 AM, it didn't really bother me as far as nausea. Just make sure you stay very close to the toilet."

For Bowel Preparation "This was my first colonoscopy, and I will admit that after reading some of these reviews, I was worried, but overall, I had a good experience with Plenvu. I followed the exact instructions that my doctor gave me for prep. The taste was not too bad. Dose two was harder for me than dose one, and I did feel a bit nauseous, but it passed. It worked great, and I had no abdominal cramps or pain. I took my first dose at 4 pm and the second at 8 pm for an 8:40 am colonoscopy the following day. I did not eat any food at all the day before the procedure and just drank the clear liquids suggested. I would recommend this prep. I am going to ask for some anti-nausea medication next time, but will request Plenvu again for my prep."

For Bowel Preparation "This is my second colonoscopy and my first time using this bowel prep. Took the first dose around 5 pm, and it was a horrible “mango” flavor, but managed to get it down. Stayed on the pot and was pretty confident I was cleared out by 11 pm. Second dose at 5 am tasted so bad it made me throw up a small amount several times afterward. Managed to get it down finally, which resulted in severe stomach pain and cramps up until the time of my procedure. The procedure itself went well, but a full day later my stomach is still tender and sore from the bowel prep cramps the second dose gave me. The pain and gas appear to be dissipating, but I would not recommend this product to anyone. I don’t remember the name of the bowel prep I used last time, but it was cheaper and didn’t have as many horrible side effects."

For Bowel Preparation "Dose 1 of Plenvu was started around 5 pm. Mixed with 16 oz of water, you have approximately 30 minutes to finish the dose. You will need it! This stuff is thick, and the taste is undesirable. I choked it down within the 30 minutes and was nauseated for about 2 hours. It took about 45 minutes for the first bowel movement, and the abdominal pain during that time was excruciating. On the plus side, it cleared me out well. Once you start, stay near a bathroom because you will certainly be using it. Dose 2 consisted of the last 2 dose packs with another 16 oz of water. Still hard to choke down, and lots of nausea. The moral of the story is that it tastes awful, causes abdominal pain and nausea, but it does what it is supposed to."

For Bowel Preparation "Was prescribed the half-dosing method. Drank the 1st half in 1.5 hrs, and it's been 4 hours and nothing. Stomach pain, headache, nausea, and sporadic chest pains. Drinking lots of water, thinking it will help, but it is just making me more uncomfortable. Dread drinking the 2nd half tomorrow and hope I don't have to reschedule. It's not been a good experience."

For Bowel Preparation "I wrote my last review after my first dose. Well, four hours after my second dose, my thoughts have changed. The first one was easy. The second dose made me nauseous about halfway through. I didn't finish the liquid because it would have made me vomit. Not that it mattered. I've spent the last four hours on the toilet. My backside is raw. It hurts so bad I cry every time I have to clean it. And I'm very dehydrated. I could keep myself hydrated with the first dose because I could drink, but I couldn't drink past midnight. Which meant I took my second dose by itself. Telling someone to take a second dose during a time when you're not supposed to drink is just cruel. Does it work? Yes. But I'm not sure it's worth it."

For Bowel Preparation "Took this stuff, Plenvu, for colonoscopy. It is without a doubt the worst tasting bowel prep treatment I have ever had (I have had 3 colonoscopies). The combination of sweet and salty is awful, and even after the colonoscopy is over, I almost get sick every time I think about it. I have a pretty tough stomach, but this stuff will make you nauseous. It is ridiculous that bowel prep medications are so foul tasting. Ask for something else."

For Bowel Preparation "After reading all the negative reviews, I was really worried about taking Plenvu, but it was nowhere near as bad as I’d feared. First impression was that the taste was better than expected - yes, it's a weird mix of salty and sweet and not something you’d drink for pleasure, but if you mix it up ahead of time, refrigerate it, and drink it through a straw, it’s entirely doable. I took 2 Buccastem anti-nausea tablets around 2 hours before each dose as a precaution. Also followed the consultant’s advice to drink it slowly over the course of an hour to avoid nausea, so divided each dose of 500ml into 4 glasses of 125ml and used a timer to make sure I finished each one within 15 minutes. As you need to drink an additional 500ml of clear fluids, I made ginger tea (peeled raw ginger root steeped in hot water) and drank some of that after each mouthful of Plenvu. Didn’t experience any nausea, and results began around 30 mins after finishing the first dose. Very effective."

For Bowel Preparation "I took this in preference to Klean Prep, as the quantity to drink was much less. This was the only difference. I took Motilium on the tongue before both doses, which stopped nausea. However, the taste and thick consistency made this very hard to swallow, and only great resolve got me through. My restricted low fiber diet was such a help. As my consultant said, what goes in has to come out! Following the first dose, I had two movements only and felt well. Same after the morning dose - which was worse than the first - but about four watery movements and just a little cramping, and that was it. However, the only way I could get this down was the lesser quantity. I could not ever take it again, and very thankfully I won't have to, as I'll be 76 in 10 years' time and no tests after 75! Great money to be made by someone who can come up with a bearable solution."

It tastes disgusting, and I wish I had listened to everyone’s advice about using a straw, sipping something other than water in between gulps, etc. The prep worked, and I had my procedure. But it’s 10:30 p.m....9 hours after my procedure...and the prep is STILL WORKING!!! I’m still stuck on the toilet."

For Bowel Preparation "On the day before the colonoscopy, I woke up and took my high blood pressure pill with a sip of water. I ate 2 gelatin at 3 pm and drank a glass of Welch's white grape juice. I mixed the GaviLyte solution the day before so it could get nice and chilled. At 5 pm, I drank the 1st 8 oz every 10 minutes for the next 3 hours until consumed. To my surprise, it went smoothly. I didn't experience any nausea or vomiting, but I felt a bit lightheaded at first. The trips to the bathroom came after about 45 minutes, and I was able to catch a few zzzz's later in the night w/o too many interruptions. (I had a colonoscopy last year and found some precancerous polyps, so I'm going back for another checkup today). GaviLyte G with lemon pack is the best!!!"

For Bowel Preparation "Took my first dose, it was horrible tasting. I could barely take a sip without gagging in disgust. I got a method of a sip of the medicine, then a sip of apple juice going, and that worked. About 8 hours later, I started my second dose, which surprisingly tasted even worse than the first dose. I drank half, and after 5 minutes, projectile vomited everything. I waited about 10 minutes and finished the rest and laid down, thinking I would be fine. Nope, as soon as I got back up, I projectile vomited the rest again. Hopefully, I will still be able to have my procedure, but seeing as I threw up all of dose 2, I’m not sure how that will go. 0/10 would not recommend, if you have any other options, please go with those."

For Bowel Preparation "Very effective way of emptying bowels. I am 18 years old and had my first colonoscopy today. The worst part of Plenvu was the taste, and I struggled very hard with finishing the liquids. I did not have any side effects such as nausea or discomfort, but I did spend a solid 12 hours in the bathroom. I still felt the need to have bowel movements even after my colonoscopy, even though my colon was perfectly clean."

For Bowel Preparation "This is the most disgusting stuff ever. How can anyone swallow this? Such an intrusive taste that you can’t tell whether it’s most sour, salty, or extremely sweet. So confusing to the brain that you need to throw up. I’m not sensitive, but this was too much. The procedure could not be performed."

For Bowel Preparation "I vomited half of the GoLYTELY prep along with most of my insides! Started drinking it at 11:30 am the day before the colonoscopy and got that half down. At 4:00 pm I tried drinking the other half and vomited it all and then some. My friend brought me an anti-nausea suppository after I vomited the anti-nausea pill and managed to get the last quarter of the solution down. Headache, nausea, chills, I feel like I drank rat poison. Never again!"

For Bowel Preparation "Ok, it does taste awful. This is what helped... First, hold your nose while you are drinking it. Also, breathe through your mouth. Second, have some Sprite or other drink ready to chase it. Third, have something in which to vomit, because you may vomit. Fourth, be near a toilet. Fifth, have some really soft toilet paper ready. A lot of toilet paper. Overall, it wasn’t the worst thing I have had to do, but it is definitely on the list. I did feel extremely nauseous after and weak. My entire digestive tract felt like it was on fire, and my anus was very sore."

For Bowel Preparation "This stuff tastes absolutely horrible. Was able to choke down the first dose, however, I threw up the second dosage but was still able to absorb enough to complete the procedure. It acted very quickly for me (in about 50 minutes) and actually didn’t hurt my stomach too badly at the time. I’m recovering now, and my stomach hurts very badly, and I feel pretty terrible, but it did the job. Overall, it’s effective but pretty unpleasant."

For Bowel Preparation "3rd colonoscopy. 1st one 9 years ago, 2nd 3 years ago. Previous Golightly and Suprep. This one (Plenvu) is awful. I think the thickness is the most repulsive part. Held my nose with each gulp through a straw and followed with iced tea, which I also mixed with the 1st dose instead of water. Second dose at 2 am mixed with water only. Not as thick, easier to get down, chased with iced tea. Couldn’t finish the last 2 oz. No cramps, not explosive, passing water BUT...it’s the color of iced tea and not sure if it’s fecal matter or just due to my drinking tea. Some preps say nothing 2 hrs before the procedure, my doctor’s office said 3 and the nurse said 4, which is it??? My husband took pills for his and it was easy for him. My doctor offered and I should’ve tried them....no more liquid preps!!! Nice if this could be administered through IV. Solitaire on iPad on the toilet helps pass the time."
