For Constipation "I have had constipation for years, tried so many things. This was prescribed to me even though I'd tried it on my own over-the-counter. I decided to use it everyday and see what happens. I did not use it alone, I was also using natural supplements like cascara sagrada and Senna. I have found that I have to switch it up because whatever regimen I am using stops working after a while. I am here reading these comments because after using Miralax for about 2 months everyday. I started having urinary incontinence. I have a constant pressure in my bladder and I have to go to the restroom more often. Also when I need to go I can't hold it, it's very uncomfortable if I try. I was working for constipation, that's why I had been using it everyday. I was already checked for infection, UTI, and other issues. So because of that I started to think about what I was doing differently. It was this Miralax, it is affecting my bladder. I just hope it's reversible."

For Constipation "Within hours of taking the recommended dose to help with post-op constipation, I basically got to relive the experience of a bowel prep all over again, but this time with violent gas pains, cramping, and bloating. I woke up at 1 AM and spent the rest of the night and following morning staggering back and forth from bed to the bathroom in agonizing pain. When the waves of cramping hit, I could barely stand or move. Excruciating! The worst part was, the consistency of my stools was so weird that I just kept having to go very little amounts at a time. It felt like the misery would never end. Especially after my poor insides had been scrambled around during surgery, this was one of the painful things that could happen. I even passed out for one hour in between all the madness and had a vivid nightmare that I was deceased and no one could help me. That is a pretty fitting summary of what taking one dose of Miralax felt like post-op. This stuff is pure awful"

For Bowel Preparation "Prep: From 5 pm until 7pm, it went down fine with the Gatorade. Around 7pm, I was doing a lot of tooting. At 7:30 pm, I started with three bouts of semi solid stools. At 8 pm, I had a few room cleaning toots and felt like I was going to throw up from all that liquid I had to drink alongside the prep (I ate Jello and drank a lot of clear broth to keep my strength up.) I completed the prep mixture as instructed. Then, nothing but watery, murky sludge from 8:30pm until 4am in 15 minute spurts. Your butt will start firing off some lava sludge after the first few bouts. It is a normal part of the prep, and it causes a definite rash where your external sphincter is. I slept from 4am until 9am and did one more sludge bout but the sludge was more yellow and only a few flecks were visible. I felt like I was going to go again on the ride up but no more sludge happened when I went to use the bathroom before my procedure. The doctor was satisfied with how clean my colon was for the procedure."

For Constipation "I have battled constipation on and off for over 20 years. Recently it has gotten bad again no matter how much water I drink or how much fiber is in my diet. I workout 6 times a week and for the most part eat really healthy. My doctor recommended I take Miralax. It has been pure nightmare. Yes it worked, but if I even feel slightly gassy I had better get to the bathroom fast. I have not had a solid bowel movement in over 2 weeks, (I stopped taking the miralax a week ago) I am gassy, poopy and have to buy stock in flushable wipes as I've gone through so many. It's like "fire in the hole." I would have thought after being off this medicine for a week things would have gotten back to normal, but it is anything but normal. I can't even go on a car ride for more than an hour as I need access to a bathroom at all times. I took it once a day and did not exceed the recommended dosage."

For Constipation "I was diagnosed with IBS-C and chronic constipation about two years ago. The doctor simply wrote me off with a prescription that didn't work. Tired of tons of prescriptions that didn't help me go and gave me have horrible symptoms, I ventured out on my own and drastically changed my diet but even that didn't work! Finally I tried Miralax because it was the only thing left and my doctor kept urging me to. I am so glad I did! I go two to three times a day and have normal stool. Sometimes my stool is on the runnier side or I get stomach cramps before a bowel movement but I am very happy with this product! It dissolves very well in any kind of drink. I recommend people to try it and give it about two weeks to work. Also, drink your water!"

For Constipation "This medication is heaven sent! We suffer from bad constipation in my family. We eat healthy and a very high fiber diet, get plenty of exercise and drink lots of water and still get constipated. Miralax is our solution for this problem, it is even gentle enough for my kids...I do not recommend taking it daily because you could get very loose stools. You could take it two days in a row to empty out and then switch to every other day or even every two days. This works for me and I have really bad constipation."

For Bowel Preparation "I used this Miralax prep last week along with Dulcolax and I will NEVER use it again. After the third dose I still had not had a bowel movement. Then all at once I broke out into a profuse cold sweat and felt as though I would pass out. I headed for the bedroom to lay down then and after about 3 minutes a wave of nausea hit and I barely made it back to the bathroom before projectile vomit occurred. This was my 3rd colonoscopy/endoscopy and NEVER AGAIN WILL I USE THIS PREP. After I vomited the poison from my system, I felt better and continued with the process. I was able to have the procedure but I told my doctor the what happened and he said from now on he would use Moviprep or Suprep."

For Constipation "I have Small Cell Cervical Cancer, a very rare cancer with an aggressive form of treatment. I had to undergo an intense amount of chemo and radiation therapy which was aimed directly at my bowels due to the field of treatment. This being said I had a lot of cells that died off in my GI tract with all treatments. I also developed an internal hemorrhoid that literally has been HELL for the last 3/4 months. Miralax has been the ONLY thing to help cure this dreadful pain during bowel movements and keeps them coming loosely every morning! This is a hugely successful. Anyone who has ever suffered from hemorrhoids during cancer treatment to that area (impossible for it to heal & miralax made it possible!) THANK YOU!!"

For Bowel Preparation "I drank the miralax in 64 oz Gatorade for colonoscopy. No other laxative used. Drank entire prep between 7 pm and 1130 pm. Nothing happened until 1230 am. Was up entire night on toilet until my colonoscopy at 630 am including at doctor office. However my prep was super clean and don’t need for another 10 years so it was worth staying up all night for. I recommend - it wasn't that hard to drink no cramping or pain just bloating feeling. Tasted fine."

For Constipation "Be patient -- it may take a couple of days -- but you will get results. Follow the instructions and take your capful each day in a liquid drink -- I use apple juice. I absolutely cannot taste any difference. You will feel the urge and there is absolutely no straining. It is a miracle OTC remedy!"

For Bowel Preparation "I just had my first colonoscopy and I, like many others, was terrified of the prep. I was prescribed a split dose which involved 2 Ducolax tablets an hour before drinking 32 ounces of prep the night before the procedure and 32 ounces 6 hours before my procedure. I am here to tell all of you that may be worried, it was a BREEZE! I started my low-fiber diet 6 days prior to my prep and followed the instruction given to me by my doctor exactly which included taking a cap full of Miralax before bed 3 days prior to my prep. I took 2 Ducolax 2 hours before I started my prep and 1 Zofran (for nausea) and 1 Gas-X (for bloating) an hour before I started drinking the Miralax solution and was done cleaning out in less than 2 hours. For the second round, I did exactly the same thing and sailed right through. I am here to tell you not to be afraid. Go get your colonoscopy - it could save your life."

For Constipation "Until about 5 years ago (when I turned 40), I very rarely had any problems with bowel movements. Then I got a toe infection which required antibiotics to clear up. It worked, but after that I started having problems with constipation. I tried more bran and fiber. It did not work. I tried eating more fruit and vegetables. It didnt work. It was getting so bad that I started get hemorrhoids that bled bright red blood when I wiped. It was scary. I had to strain and strain just to get to the bathroom. I tried prunes and prune juice, and when it did work, it gave me the runs and lots of gas and cramping. I tried magnesium, and in order for it to work, I had to take so much that it gave me the runs unexpectedly. Miralax worked for me."

For Constipation "The first day I took MiraLax just once it wasn’t working so the second day I took it again and it still wasn’t work. On the third day I took it again then now on the fourth day ( today ) I can’t stop pooping. When it first started working I loved it but now I can’t stop pooping. Don't get me wrong I’m glad I’m pooping because I was so backed up - but now I’m not back up and I’m still just pooping all the time. "

For Constipation "I've had chronic constipation since I was four. It was so bad that I literally had to see a "poop doctor" until I was about 7. I started using Miralax whenever I was constipated at that point, and never once has it failed me. I once had a 2-week period of constipation, my worst period of time ever, so I began taking one capful twice a day. Two days later, I produced two toiletfuls of stool. It ached a bit afterwards, but the process was very, VERY quick and you could NOT believe how relieved and relaxed I felt afterwards. I'm in my late teen years now, and I still take it whenever I haven't gone for at least 3-4 days. It usually takes a day or two to work, but it's completely worth it."

For Constipation "Just been on this for 2 days. Don't know if I'm gonna go but one cap=1000 facts!! If this can make me go without the pain I experienced with ex lax I'm all in :) Took xlax a week ago and 12 hrs later every inch of my body was sweating from my eyebrows to my Nuckles. I didn't know knuckles could sweat. After an hour of extreme pain and making baby Jesus all kinds of promises I finally went. I started the miralax the next day and I have not gone but I'm sure it's coming.... The problem with the gassy side effect is I work with one other person in an office. Who do you blame it on?"

For Constipation "This drug was effective for me. I went through a bout of severe anxiety and panic for about 3 weeks. I lost 25 pounds and did not eat much of anything for 2 weeks. As a result, my digestive system basically shut down. When I began to eat again, I did not have a bowel movement for 15 days. I took a Dulcolax pill and had extreme cramping, dry heaving, full body sweats, and painful bowel movements where I needed to be close to a toilet all day. I went another 8 days without using the bathroom and I tried Miralax. I only took 1/4 of the dosage and within a day I had 3 bowel movements. I did have some minor cramping and I did sense an urgency to go and could not have held it, but it produced soft movements, not explosive painful ones."

For Constipation "I have been taking MiraLax for 2 months now due to constipation and hemorrhoids such a blessing to me! Before MiraLax, I used a Docusate Sodium for 6 months and it stopped working for me which caused me to be constipated again and it was leading me to extreme depression. I used MiraLax and it has not let me down at all!!! I love it and I highly recommend this to anyone who is suffering from straining and constipation!!! Thank you MiraLax :)"

For Constipation "If your constipated it can take a couple days maybe even a week it all depends. . Keep taking it till you get a bowel movement and keep taking it if your someone who deals with constant constipation for whatever reason. I was on opiates for 10yrs unfortunately.. but some people need them but if you need them for life long pain then you better never plan on getting off them cuz you'll experience the worse thing in your life physically and mentally even when your clean you forever deal with severe depression/ anxiety along with body pain.. I ended up having to get on methadone cuz I couldn't handle being off opiates, so that also gets me constipated but I use this 1cap day havent been blocked up since! Stool softeners dont work, only miralax"

For Constipation "I hadn't had a "satisfying" bowel movement for weeks. Just a little bit here and there. I weight lift and monitor my calories and weight so I knew the constipation was getting serious when my weight was up by at least 5 lbs despite being on a "cutting" diet. I took miralax over two days (two doses total )- and wow, it really worked. Once I went to the bathroom, it was like a floodgate opened (sorry for the graphic description). But it came out firm yet soft. I had no painful urgency or side effects, just a natural urge to go. The only negative side effect I had was painless gas. Lots of it. But totally worth getting back to a regular state. I'm going to keep taking this for a few more days just to make sure I get back to regularity."

For Constipation "From a combination of stress and a poor diet, I experienced some constipation last week. I did not have a solid bowel movement in a week. After seeing multiple ads on TV and reading reviews online, I decided to give Miralax a try. I found this drug very effective. I experienced results after just two days taking it. I would mix a pouch of Miralax in my morning fruit smoothie for twice the stimulation. Today is day 5 of my one week trial and Miralax continues to work. I am so relieved to no longer be constipated. I have a lot less abdominal discomfort as well."

For Bowel Preparation "I am 74 years old and today was my 5th routine colonoscopy. MiraLax was the easiest prep that I have ever consumed. I mixed it with Crystal Light and it was just like drinking lemonade. There was no additional taste, flavor, or consistency to the Crystal Light. I had no nausea, gas, cramps, or any side effects. My doctor said my colon was clean and easy for him to see inside. The only negative is you must consume 32 ounces at 2 different times. I found drinking through a straw helped me drain it quicker than drinking from a glass. I have never tried the pills. I did not want to consume 32 large pills. Compared to Suprep and other liquids I have had, MiraLax was hands down the best liquid prep for me."

For Constipation, Acute "I've been constipated for some time and I couldn't have a normal bowel movement, and then a friend reccomended I try Miralax because they were hospitalized and having problems, but I tried it the first day and I loved it so much that I do it once a day every day to once every couple of days. I highly reccomend this to anyone who suffers with constipation. And it also mixes in well with anything you want to drink, so it's tasteless and easy to drink."

For Constipation "This stuff makes me poop every time I urinate. Once it kicks in, the effects last for several days. I have completely abnormal bowel movements. I can never get it all out, it just sits in my rectum, causing a great deal of "mishaps". I finally had to go and get an enema just so I could have an actual bowel movement and clear everything out, so to speak. I'll never use the stuff again."

For Constipation "My wife was into day 5 of post operative constipation. We were starting to get concerned. We had followed dietary recommendations. On day 5 her surgeon directed her to use Miralax. I ran out and purchased it. No obvious effects on day 5 when she took it (but very little extra bloating, gas, or other side effects). Bingo, at 6 am on the morning of day 6 things returned to normal--happy for her. Thus far she has stayed regular with that single dosage on day 5. I don't think we could be any more satisfied with this product--especially for this specific condition."

For Constipation, Acute "Miralax is amazing! Give it a few days to work. It’s not instant, but it works. I promise. I’m 17 weeks pregnant and hadn’t pooped in 5 days. (Trying to go made me cry, sweat, and bleed. It felt like I was stuffed up with a softball.) I was ready to go to the ER for manual disimpaction :( Then, on day three of using Miralax, I pooped! Yes!! I literally skipped and ballerina-twirled out of the bathroom! I texted my husband and best friend that I POOPED! I can’t wait to gift a bottle of Miralax to all my pregnant friends :)"
