Reviews for Polyethylene glycol 3350 with electrolytes

Plenvu (polyethylene glycol 3350 with electrolytes): “Want to lose 13lbs in 2 days along with all your electrolytes, every single drop of water in your body, and your general will to live? If so try new Plenvu bowel prep, where are motto is "if you didn't have hemorrhoids before, you do now! Dose 1 comes in our great new mango, burned car tire, toilet bowl cleaner sludge flavor! Take it before bed to ensure you get zero sleep and wake up hating everyone and everything. If you survive the night you get rewarded with another dose at 4 a.m. This one comes in the only slightly less repulsive flavor of fruitpunch, saltwater, and enough Aspertame to give cancer to an entire 3rd world country! Side effects include pooping your brains out for days before, during and after your procedure, anal bleeding, severe muscle cramps, joint pain, headache, severe dehydration, and hoping you poop on the doctor who made you wait an hour and a half after your appointment time to begin your colonoscopy.”

Plenvu (polyethylene glycol 3350 with electrolytes): “I was freaked out after reading all the negative reviews. I have anxiety about taking medication and I knew this wasn’t going to be pleasant. But it really wasn’t that bad. With Plenvu I had no side effects other than the wanted diarrhea. No pain. No anxiety. No dizziness. No vomiting. It doesn’t taste great but it’s not horrible either. It started working an hour after I finished the prep.”

Plenvu (polyethylene glycol 3350 with electrolytes): “It works, but I really can’t believe this is on the market. I suggest a liquid diet the day before starting this. It helped. I took the first dose about 5:10pm the day before my procedure. I could not finish it all in the half hour. In about 30 min it started working and I was on the toilet about every 5-10 min for the next hour or two. I fell asleep from 9-10 pm, then woke up, went some more, then slept from about midnight to 430 am when I had to take the 2nd dose. So...the roughest part...the second dose is so awful. I tried a sip of solution, a sip of Gatorade back and forth and it didn’t help. I even shoved a slice of lemon in my mouth at one point - nope. I only got half the solution down then quit because my body was telling me to stop. An hour later I threw it all up but it still had me going clear. Side effects I experienced are headaches, chills, nausea, vomiting, dry heaving, diarrhea - but it was gentle. My advice: if your body is telling you to stop drinking, then stop.”

Plenvu (polyethylene glycol 3350 with electrolytes): “Started prep at 6:00pm night before procedure. Added ice and sipped it through straw. I had ginger ale for in between as needed. It's salty/sweet but not so bad you can't handle it. Drank water and some clear grape juice later on. I had no issues. A few stomach cramps as things started moving. It took about 2 hours for it to start working but was in bed by 10pm and slept great the whole night. Next morning, step 2 of prep. Started 6:00am with water. Things really started to move and I was running all clear by 9:00am. The only part I couldn't done better with was getting more to drink before the procedure because my appointment was running over an hour late and I was extremely thirsty and couldn't have anything until afterwards. All in all things went as smooth as they could've gone. For anyone reading this, don't be scared of doing this prep. My biggest advice is to have light meals the days leading up to your procedure. I really think that helped me as well.”

MoviPrep (polyethylene glycol 3350 with electrolytes): “Ok I hate this stuff it gives me nightmares it's absolutely vile and impossible to finish. The only way I can get it down is chilled through a straw it's like a military operation I have a glass I pour it into then I have mouthwash for straight after each drink to get rid of taste and I try to get it all down in half an hour that's between gagging and eventually throwing up. I think in this day and age someone somewhere could come up with something that doesn't taste so disgusting. It triggers nausea and migraines. Anyone who drinks this deserves a medal.”

MoviPrep (polyethylene glycol 3350 with electrolytes): “Read a number of these reviews beforehand - very intrigued when I finally got round to taking the first 1 litre prep. It didn't taste too bad - chilled it and sucked on a lime wedge before; but nevertheless, it wasn't as bad as some people have made out. Sweet and salty but got the 1 litre down in around 45 mins. Movements started just before the hour mark; about 40 or so minutes of regular 'wee poo' then intermittent trips back for another hour or so. Really - no big deal. Morning prep went down just as easy and as everything was already clear after the first prep (you're looking for yellow liquid), the toilet got less action. Vaseline and wet wipes are a good idea. Remember to hydrate - I matched both rounds with 1 litre of diluted juice and it was all fine. Unless I royally shite myself on the way to the appointment, I'd say it's been a relatively decent experience. Best of luck with your respective evacuations.”

Plenvu (polyethylene glycol 3350 with electrolytes): “So it really is the more horrible vile thing I have ever tasted. That being said, you can get through it! It is only 16oz.! I fasted for 48hrs.,broth, jello, popsicles and water. That really helped the “movement” part be a lot less severe. I mixed the stuff in cold water and refrigerated it for approx. 4hrs before I drank it. I alternated small sips of the drink with small sips of ice water. I sucked on spearmint lifesavers in between sips. I took the whole thirty minutes to drink it. No gagging, no vomiting, no nausea. I also started it two hours before directed time of 6:00 pm. I was in bed by 10, up again at 2:00 for second dose and finished in time for the procedure. The second dose was worse as far as the “movement”. It took longer, about four hours. So no sleep, but no other side effects. I don’t know if would do it again, and the product is really awful but you can make it through! Don’t panic! You can do this!!! Good luck to all!”

Plenvu (polyethylene glycol 3350 with electrolytes): “This is the worst experience I have ever had with any kind of medication in my life. Started yesterday at 5pm. mixed with cold water and used a straw to drink. This stuff is extremely salty and over flavored with artificial fruit flavoring. It is very intense and there will be an awful salty after taste. I instantly felt sick to my stomach. I tried to remain calm and relaxed and sat still. Drank plenty of clear liquid behind it. About 45 mins after I completed the first does I went to the bathroom for first BM. During that time of having my BM, I became very hot and sweaty. I started feeling awful. I knew I was about to get sick. I wound up throwing up at least half of what I had drank. Got up at 1:00am to start the second dose. Decided to drink this one even slower to see if that would help me from getting sick again. Took about 45 mins to drink it all this time. Taste is so horrible. Just awful. I made it thru and instantly started feeling very full and very sick.”

Plenvu (polyethylene glycol 3350 with electrolytes): “As with most things online (especially where drugs are concerned) people only tend to post reviews if there are problems. If things go well, they think nothing of it and just move on with their lives. At this moment, I am almost at the end of the prep. I am actually sitting on the throne with my iPad on a chair in front of me. I took twice as long to drink it than instructed - both doses - and experienced no nausea whatsoever. I matched each sip of Plenvu with a sip of flavoured, bottled water - non fizzy. Plus I’ve drunk a lot more water than instructed. A ton more. I feel fine. I’ve used a barrier cream after every movement. Another hour and I hope I will be able to get to bed. The worst part of all this is my back and leg ache from sitting on the toilet for so long! Plan your time carefully. Take longer and drink more - much more. I hope this helps balance the reviews here a little ... Good luck!”

Plenvu (polyethylene glycol 3350 with electrolytes): “This Plenvu is by far the worst tasting prep I've ever had. It has a salty, bitter and thick consistency which makes you want to gag. The nausea I felt was immediate. Adding ice to the container helps a little to alleviate the vile flavor. It's filled with aspartame, which worsens the aftertaste. Surely there has to be a better prep. This is absolutely disgusting.”

Plenvu (polyethylene glycol 3350 with electrolytes): “I'm happy to report, no major issues with Plenvu. No cramping, no nausea, no vomiting. Ate a bland diet on the day before the prep. Ate only clear liquids on the prep day. Started prep at 4pm. Allow the full 2-3 min to let the stuff dissolve. I didn't chug it, but did get it all down within 15-20 minutes. Taste was bad, but not as vile as people have described. Started working within 2 hours. By the end of phase 1, stool was liquid, but still not clear. Went to bed by 10 with plans to get up for dose 2 at 4:30. No accidents or issues. Took my time w/dose 2. As nasty as it tastes, slow and steady (20 min total to drink) worked for me. I followed hot tea to help keep the chills away. Dose 2 worked quickly. Went several times for about an hour and achieved the clear, pale yellow outcome, and went back to bed for 2 hours. Doc said prep was excellent. No problems after.”

Plenvu (polyethylene glycol 3350 with electrolytes): “Never again! This was my second colonoscopy and the first was not this bad. My insurance copay was $60 so I expected it to be “new and improved “. The first dose was tolerable but nasty.. It started working before I finished drinking it (about 15 minutes). The second dose at 3am was horrible. I had about 2 oz left but stubborn me determined to finish even though I was nauseous. Suddenly I started throwing up violently. I went to the bathroom just as violently and so irritated I couldn’t sit. Awful!! My question. Is why is the same dose required for a 300 pound male as a 125 pound female. Definitely felt like overkill like killing a fly with a hand grenade! No more Plenvu for me!”

Plenvu (polyethylene glycol 3350 with electrolytes): “1st time, so worried after reading the reviews. Female, 5'6, ~135 lbs. What I did worked well: - Prepped right before drinking (shook for 7-8 min) - Sipped with a straw over 25 min; repeat for H20. Slightly nauseous (2/10) but started going within 10 min afterward, so got distracted. Within 1 hour, only cloudy liquid and in 2 more hours, <urgency - Next dose 9.5 hrs after 1st. Note - doc's office said 10.5 hrs after 1st (4.5 hrs before colonscopy)- which I would not recommend. Start 2nd dose>=5.5 hrs ahead of when you leave. If I'd started 4.5 hrs before, I would've still been on the toilet. - 2nd dose harder to tolerate - sip slowly & burp Also had 96 oz of cool H20 between 1st/2nd dose+32 more after 2nd dose. Staying hydrated helped a lot. Tastes like a supercharged Gatorade to me, with a thicker viscosity. Very sweet & very salty at the same time. Am actually glad they added the sweet, as can't imagine how salty it actually is if even with the sweetness, you can still taste all that saltiness.”

MoviPrep (polyethylene glycol 3350 with electrolytes): “Despite the side effects of nausea, vomiting and taste, I have to keep in mind that it was beneficial for my overall health. I am a 4 time survivor of colon cancer. I would rather spend a few days out of my life enduring this than going through chemotherapy and loosing the battle to cancer as my father and grandmother did.”

Plenvu (polyethylene glycol 3350 with electrolytes): “I would like to rate Plenvu 0, not even a 1. Worst prep ever, started procedure at 4:00 PM, was still eliminating waste (or water) at 5:30AM. Actually until the procedure at 9:00 AM. It was the nightmare night, no sleep! Ended up passing out a week later from low Potassium. Fell and had 4 stitches in the forehead, very light headed. All because of this product. I've never had a body imbalance like this in my life. Please do not take this! Same product they would give to a 300# man as they gave me and I'm a female weighing way less than half that!”

Plenvu (polyethylene glycol 3350 with electrolytes): “ASPARTAME ALERT! The Plenvu kit came in the mail from a specialty pharmacy and cost me $60. I opened it two days before my procedure as the box top recommended, and was alerted by the "phenylketonuric" warning -- it must have aspartame in it (although that's not listed on the box), and it's an ingredient that gives me irregular heartbeat. After perusing the enormous tissue-paper-thin package insert with a magnifying glass, I finally found that aspartame is an "inactive" ingredient in Pouch 2. I couldn't use this prep and went back to the classic Gatorade with Ducolax and Miralax, and am a happy camper since it was a fine experience. But I'm still out $60 because no one at the doctor's office asked me if aspartame was a problem before calling in the prescription for it, and the pharmacy is only in the business of filling orders, not questioning them.”

Plenvu (polyethylene glycol 3350 with electrolytes): “It three hours post taking the 2nd dose and I not sure if I am finished yet, but I am at yellow output stage. I am writing this before I forget to. Because in reading some of these reviews I was afraid of this as a first time colonoscopy patient. The drinks are gross but not undrinkable. I alternated between the prep and ginger ale. I also used refrigerator cold water to make my prep and drank it through a straw. Last night it took more than an hour for the first dose to work. I started at 4 pm was done well before bedtime. This morning started at 6:15 and it took less than 30 minutes for things to start moving. The morning dose does not give you much warning, stay very close to your bathroom. I think, because it's mostly liquid your ability to hold it is less effective than when it's solid or even diarrhea. I've never done it with the other preps, but as far as I can tell, this is better than drinking the gallon of the other stuff.”

Plenvu (polyethylene glycol 3350 with electrolytes): “I was recently prescribed Plenvu for my colonoscopy. I was happy to learn that it was only 2 doses of 16 oz each as compared to the other preps that required you to drink much more prep. After my first sip of Plenvu my happiness turned into terror at the absolutely horrid taste of this prep. Think thick and VERY salty with a nauseating fake fruit flavor. I could barely choke it down and would have vomited it up if not for the anti-nausea script provided by my GI. Yes, you drink less fluid but the solution is simply MUCH MORE concentrated than in other preps. Even using a straw to try to avoid my taste buds did little to make it any more palatable. I have had 6 colonoscopies and this was the worst prep I ever used.”

No discomfort at all, worked within hour. Both preps were easy to take and no negative effects. Makes Golightly seem like water boarding torture!”

And you can’t wait til it’s over. Things you should know, Get soft toilet paper. Have disposable wipes. Use Vaseline. Your bum is going to get irritated because of frequency of movements and wiping. Honestly the worst part was the pain from my irritated bum.( outside of the drinking of the prep) I started at 12 pm and did second dose at 6pm. It’s constant bathroom trips. So be ready. But I could honestly say that if I knew to have the things I listed when I started this it would have been a lot more tolerable. I wish someone would have told me...”

Plenvu (polyethylene glycol 3350 with electrolytes): “This is absolutely the worst tasting thing I have ever come across. The "fruit flavors" don't help at all. If anything they make it worse. It's a combination of really sweet and really salty and quite frankly I don't know if there's anything worse. A new formula is absolutely necessary because judging by the reviews, 9/10 patients have mutual feelings towards it. Absolutely disgusting.”

Plenvu (polyethylene glycol 3350 with electrolytes): “I've just finished part one of two part prep. GoLytely was far easier. This took me two hours to choke down. I am nauseated and cold. I just feel sick. I did get a little relief from the suggestion of sucking on lemons after each drink. The taste is repulsive beyond description. I'm scared of the next part when I get up. I will edit this when I'm done if possible. I pray I never have to go through this again. I'm a retired RN and have been in charge of an endoscopy unit.Part 2... so nauseated can't finish all of second solution. Still drinking water. Woke with headache and chills. Chills continue. Dizzy. If I can't have this colonoscopy I don't think I can go through this again. My butt is bleeding. Never been do sick in my life. Never again. Who made this up? Rating 2 because I think I'm cleaned out but the side effects are horrific.”

Plenvu (polyethylene glycol 3350 with electrolytes): “After reading these reviews I was terrified to take this prep but it was all I had so I did it and...not that bad. Of course you are emptying your bowels it's not the most fun but this was not that bad. I have taken laxatives that had me curled up in a ball on the bathroom floor, this was not the case with Plenvu. I feel it all depends on your preparation. I followed the directions strictly and honestly did not eat a ton 2 days before because I knew this was happening. If you follow the directions you should be fine, yeah it sucks not eating but it is worth it. Because of the magnesium Citrate I had two days before my procedure (which was way worse than this) I really only had liquid BM's and I had to go to the bathroom every time I went but I could hold it just fine, I went about every 40minutes after taking the second dose. I hope this helps someone who is scared of taking this”

GoLYTELY (polyethylene glycol 3350 with electrolytes): “After reading all the horror stories I wanted to cancel procedure so thought I'd share my experience. Honestly NOT THAT BAD! Took as directed, added nothing for flavor. Tasted very salty, just a swig of Apple juice after each 8oz dose, every 15 mins. Had no side effects. No bloating. No gas pains. No discomfort. Had only broth on prep day. Had only a chicken omelet afternoon prior to prep. No cramping with bowel movements. Procedure was a breeze, without the "wind". Hope this helps ease someone's anxiety.”

Plenvu (polyethylene glycol 3350 with electrolytes): “My experience was a breeze. Took 1st dose the day before at 2:30pm, had a significant "diarrhea" bowel movement about 30m later, not much. No sitting on the toilet for hours, no soiling my pants... Got up at 4:15am for the 2nd dose, had 3 mostly liquid bowel movements before heading to the hospital. No risk of "losing it" before reaching the bathroom, should have gone back to bed. I was afraid to go back to bed. Last bowel movements clear and yellowish, post procedure notes state that the prep was excellent. Taste wasn't great, Gatorade didn't really taste better. Used a straw, drank the 16oz in 3 big gulps. No biggie. Drank an extra gallon over the prep time: tea, water, Gatorade, chicken stock... Stopped 2h before procedure. Everyone is different, but it was hassle-free for me”
