For Bowel Preparation "Terrible product. The Gatorade and Miralax prep was much better without the side effects. Plenvu was awful tasting and caused severe nausea. The nausea lasted into the second day after the colonoscopy was completed. I plan to tell the doctor that I do not want to use this product again."

For Bowel Preparation "This was my first time using this prep for a colonoscopy. One hour after the first dose, I started having explosive diarrhea. This continued through the second dose and throughout the night. I got no sleep. I started becoming nauseous, weak, and began having burning pain on my skin wherever the diarrhea fluid touched the skin on my bottom. By morning, I could not touch the skin without excruciating pain. I was so weak by the time I got to the surgery center for the procedure, I requested a wheelchair. Having done previous preps for colonoscopies, I cannot recommend Plenvu. It was much too harsh on my body. It is now 2 days since my procedure, and I am still recovering from the pain and exhaustion from using Plenvu."

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 too had a negative experience with Plenvu. The taste was horrendous. It started working within 15 minutes of finishing dose 1. I was so nauseous and clammy I thought for sure I was going to pass out. I couldn’t finish the second dose as the same thing happened. My blood pressure was also very high for me after the second dose. I was crampy and bloated for weeks after and still don’t feel as good as I had before this prep 6 months ago. I wouldn’t recommend this prep to my worst enemy."

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 "First, I'll say that my Boston Prep Scale score was a 9, which is the perfect score and means that your prep worked and your colon was optimal for visualization. As far as effectiveness, Plenvu did the job. That said, if I ever have to have a colonoscopy again, I will ask to try a prep other than Plenvu. The taste of dose 1 was so vile, but I kept it down and it did its job. Dose 2 was less vile tasting, but my stomach expelled it in 20 minutes in the biggest projectile vomiting I've ever experienced. I hope to never have to have another colonoscopy."

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 have had three colonoscopies, and this prep was by far the worst, BUT very effective. I started the first dose at 6 pm and had a hard time drinking it all. Within 20 minutes, every negative side effect started ... bloating, nausea, runny nose, chills, feelings of nervousness, and need to vomit, which I did. It kicked in relatively quickly. I drank most of the first dose but not all and went to the bathroom until about 10 pm. I called the doctor, and he gave me tips, including drinking ginger tea. I tried to sleep before the 1:15 am dose #2 but could not fall asleep. I tried to finish before the side effects started again but could not. I left about 1/4 that I just could not choke down. All the same side effects. I went to the bathroom until about 4 am and tried to sleep but could not. I went to the bathroom another 5-6 times before the 8 am procedure. Even though I did not finish and vomited the first dose, I still had clear discharge before the procedure."

For Bowel Preparation "First time for a colonoscopy, had PLENVU prescribed and took it, but nothing to compare it to. Dose 1 the night before was like drinking fruity seawater, but I got it all down. In less than half an hour, the floodgates opened—success! It works!! (No “false alarms” with this stuff, so be near the potty ;-)). Felt nauseous with it but figured it’s all part of the process. Slept fine that night, next morning on to dose 2. Flashback to last dose. After finishing dose 2 (and during), nausea started again but knew that was normal. Unfortunately (or fortunately, as the case may be), projectile vomiting of dose 2 commenced, luckily into the toilet. A LOT. But some must have made its way through my system as the projectile “squirts” commenced as well. Sure felt better after the vomiting, though!! Called my doc’s office after this vomiting of dose 2 episode and was told don’t worry, just keep pushing fluids. So I did. No problem with colonoscopy being done. And that was it!!"

For Bowel Preparation "Plenvu split dose: Easy to use. Taste is perfectly acceptable. Dose 1 better than Dose 2. Worked very fast on me. Bowel prep is not a pleasant undertaking, but Plenvu is lower volume, so taking it is not a matter of ingesting a lot of liquid. I had short-lived episodes of nausea with both doses. They were both fleeting and very tolerable. If you do a good job with diet a couple of days prior to the actual bowel prep, your experience with Plenvu should be just fine. Remember: You're cleansing your bowels, it's bound to wreak a little havoc on the gut."

For Bowel Preparation "My first colonoscopy. I'm 52, so it was time. Took the Plenvu with 16 oz of water at 2 pm the day before my procedure. The taste was horrible-like someone mixed melted gummy bears with ocean water and some pepper to boot. I could barely get it down. Thirty minutes later, a fire hose of hot liquid lava flushed out of my ass. Every time I thought I was done and could finally flush and attempt to stand up, another round of open faucet drainage came from my butthole. I was not aware the anus could flush like that, but it can. I was dreading the second dose, which was at 10 pm (the night before the procedure). I was right to have dread. The second dosage evoked an immediate gag reflex-as if my body yelled, 'I've seen this horror flick before, and I'm not going to watch it again!' How I didn't throw up, I don't know-perhaps it's because all my bodily fluids left 10 hours earlier. With the second dosage, I was on the toilet well past midnight, fearing I would permanently ruin my mattress if I laid down."

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 "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 "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 worst tasting prep I've ever had, the taste is so bad I was gagging the entire time. I had chills from trying to tolerate the nausea it caused. It took hours for it to get better. The first dose worked an hour and a half after taking it. I could not finish the first dose. The thought of the second dose had me in tears. Never will I take this again in this life, NEVER!"

For Bowel Preparation "I was glad I only had to drink half as much prep as I did ten years ago, but the nausea, vomiting, and chills were unexpected side effects. I know there is some really bright person who can develop a better prep that doesn’t include drinking horrible liquids that cause such nausea and vomiting and a general feeling of being ill. I am not exaggerating when I say this prep tastes horrible, and the thick salty sweet is almost impossible to drink. I hope it works, and I can have the procedure tomorrow morning. If not, I won’t repeat this prep again and will ask for the older stuff that was bad but didn’t make me sick."

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 "It was painfully rough drinking the Plenvu solutions. I suffer from gastritis, and this gave me such nausea that I can't help but wonder why I was sent this poison. It is effective since I keep going to the bathroom, but drinking the solution was absolutely excruciating!"

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 "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 "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 "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 "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 "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."
