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 am 65 years old and suffer from diverticulitis. I ended up being hospitalized and did get better, but not totally. One day, I was in horrible pain and vomited. I had an impaction. The doctor gave me high doses of antibiotics and prescribed MiraLAX. That was a few months ago. I only take as needed, as the pain on the left side signals trouble. As long as I don't get constipated, thanks to MiraLAX, I am okay. This stuff works for me. I buy Costco brand since it is cheaper."

For Constipation "I have constipation due to irritable bowel syndrome. After using many other laxatives that helped for a while, MiraLAX (RestoraLAX in Canada) is the only one that has helped me have a regular bowel movement every morning without cramps, gas, and bloating. I've been using it for about 6 weeks with no side effects. I take RestoraLAX every mid-afternoon and drink lots of water all day."

For Constipation "I took the normal adult dosage of MiraLAX because the medication I’m on for my gastroparesis is making me constipated. Here it is, around 4 hours later, and I’m nauseous, dizzy, my heart rate is up over 100, and my stomach hurts. Plus, I am still constipated. I’m laying in bed on a sunny, beautiful day when I could be outside because I can’t even lift my head up off my pillow without being dizzy and nauseous. I’m never taking this stuff again!!"

For Constipation "I haven't used the bathroom like I was supposed to in the last month. I have taken Fleet and other laxatives, but they just did not work. I felt so bloated, and I never stopped eating. Finally, I couldn't take it anymore, so I went to the doctor, and she prescribed me something to take. The medicine that she prescribed for me wasn't covered by my insurance, so I went to Walmart and saw that ClearLax had almost the same ingredients. I bought some apple juice and mixed it together. About an hour later, I really used the bathroom, and I feel great. If it works for me, it is some good stuff, and I am serious."

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 instructions 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 "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 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, 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 what happened, and he said from now on he would use MoviPrep or Suprep."

For Constipation "I have had normal bowel movements most of my life. Then I turned 29, and it started slowing down dramatically. Genetically, my father had gastrointestinal issues such as IBS, and he had food sensitivities. I am now learning all about this and had been suffering for 2 years with constipation. Stool softeners were so harsh on my stomach, but I took them because they worked. Metamucil wasn't effective for me and still left me with bad constipation, as well as laxatives, salines, and suppositories. My gastroenterologist recommended MiraLAX, and I initially had to wait almost 3 days. Then it was diarrhea because I was so backed up. So now I have a happy medium. The amount I take every day that gives me relief, comfort, and regularity. I go anywhere from 2 to 4 times a day, soft to semi-loose stools. I couldn't be happier and healthier, I recommend trying this ASAP!"

For Constipation "I have IBS-C, and over the years, have tried just about every laxative out there. My doctor prescribed me MiraLAX in 2008, and I took it daily until 2014. This is a very gentle laxative that can take several days to work. It's completely flavorless. The only side effects I noticed were minor bloating and gas. Eventually, my body got used to it, and MiraLAX stopped working. But for six years, it was painless, dependable therapy that I was grateful to have."

For Constipation, Acute "I suffer from syringomyelia. This is a condition that severely affects your nervous system. The stools that my digestive process produces kind of change from day to day. Since I am already on a whole foods diet without any dairy or wheat products, sometimes I'm regular. Other times my stool will either be too hard to get out and thus will stay stuck inside of me for a few days, resulting in terrible gas/bloating. Other times my stool will be completely liquid, and yet because my nervous system is not responding correctly, I just can't flush it out of my intestines. Whenever my bowels are not functioning correctly, all I need is a small dose of Miralax in a cup of water, and within 20 minutes, I'm able to go no problem. Highly recommended."

For Constipation "It actually works really well for me. Especially when I was an opiates user and didn't take any laxatives, my stools were so hard and big that I would resist going as long as I could because I was so afraid of the pain. On average, I wouldn't go for 2 to 3 weeks, and there was once I didn't go for 2 months and had to go to the ER. I'm now taking a medicine to get off opiates called methadone, and my bowel movements aren't nearly as painful but still give me problems. After taking MiraLAX, my bowel motions would come out with absolutely no pain, but if you don't do it every day, it will keep happening."

For Constipation "Been constipated for years and only have a bowel movement once every 4-5 days. I've been taking this for 5 days and still haven't gone. It's made me extremely bloated to the point where I look 8 months pregnant, and I usually have a pretty flat stomach. Maybe I need to try a stronger laxative, but this just doesn't seem to work for me."

For Constipation "I've been taking ClearLax for a little over a week now. I kept complaining to my wife for years about bowel movement troubles. She told me if I'm having so much trouble to buy some Miralax. I found ClearLax with the same ingredients as Miralax. Anyway, my constipation was driving me crazy and was painful. I was having trouble with hemorrhoids, stomach cramps, bowel movements, and etc., you name it. I no longer use Preparation H and feel great."

For Constipation "I've suffered from constipation most of my life, using different laxatives such as senna, Dulcolax, milk of magnesia, suppositories, and enemas. They worked, but they would also give me very loose stools and/or horrible stomach cramping. I was having another bad bout of constipation, alternating 3 days before I would have a BM. Decided to give MiraLAX a try after my brother, who also had chronic constipation, recommended it to me. I took it after a meal before bedtime, and I noticed my stomach was gurgling but no real discomfort, I think I could feel the stuff moving everything through the colon. Woke up this morning, and after drinking some more water, I was able to finally have a bowel movement that was firm yet soft and not watery whatsoever. Finally, relief! I'd also like to note that I usually strain really hard to have a BM, but with MiraLAX, all I had to do was relax, and it came right out. Would definitely recommend!"

For Constipation "I was lulled into a false sense about this drug by my doctor and reviews, which said it would work over several days and help me have a natural bowel movement. This is not my current experience. I haven't had a real bowel movement in 9 days, which is the first time in my life this has happened. I have some health issues and have been eating 400-600 calories per day. I took the MiraLAX at 7 pm, assuming nothing would happen for a few days. At 9:15, abdominal pain, cramping, running to the bathroom. Sweating bullets through my clothes and feeling incredibly nauseous, it took a while, but it started working. Almost 2 hours later, I am hoping the worst is over. It was effective because it is working, but be aware it CAN work fast and feel terrible."

For Bowel Preparation "I tried the MiraLAX colonoscopy prep about 3 weeks ago because I didn't want to have to drink the traditional prep, and it sounded less awful. BIG mistake. I did exactly as I was supposed to, liquid diet, etc., and this made me so sick, I was up with diarrhea and vomiting all night. Not only that, my 8:30 am colonoscopy had to be canceled because I was nowhere near clear, even though I had taken all of it per instructions. It has taken me 3 weeks for my bowels to become normal again, and I'm getting ready to do a 'make-up' colonoscopy using the traditional yucky drink. At least the yuck will work. MiraLAX as an occasional laxative is fine, but never for colonoscopy prep, at least not for me."

For Constipation "Smells like Elmer's glue and kind of gives my stool the consistency of it, too. It really works more as a stool softener than a laxative for me. Which is good when I'm having a lot of dry, hard stools, but the somewhat sticky texture leads to some incomplete bowel movements and a lot of unpleasant cleanup afterwards. I'd almost just rather pass the hard stool than have to go through a box of wet wipes every time I poop."

For Constipation "I have chronic constipation due to medications, mainly my pain medications, and I take MiraLAX on occasion, and it works, but for me, it takes a full 3 days for it to kick in and get my bowels moving again. I recommend taking this as soon as you get constipated, for some, it works as soon as 12 hours. I've had no issues with MiraLAX, and it works for me."

It was the first time my prep was not sufficient to proceed with the procedure, even though I followed the instructions exactly."

For Constipation, Acute "I’ve used MiraLAX previously with success. Most recently, after a number of issues, a change in diet, and medication changes, I had developed significant constipation issues. After a few days of discomfort and a fear of straining creating other issues such as hemorrhoids and diverticulitis, I decided to give it a try again. Worked within an hour on a full dose. No major cramping or pain, but definitely a need to go. The most uncomfortable side effect was the excessive sweating. Didn’t last long but was quite uncomfortable. Some mild nausea when it first started, but ended quickly as I continued to have bowel movements."

For Constipation "I had been struggling with constipation since I was 19 from taking Tylenol 3's for pain and had tried every laxative imaginable. I even tried colon hydrotherapy and that did nothing for me. I am now 24 and have been taking MiraLAX for the past month, and I have never felt better. It feels great to be regular again. Prior to MiraLAX, I was going once a week."

For Constipation "The MiraLAX is really easy for me to use. Very effective. The reason for posting is I was wondering if there was a way for a person like myself who has used this product for many years... could have an easier way of pouring it into a water bottle, for example. Much like Crystal Light packets, but in a way so it does not copy the Crystal Light company's idea. Yet it is still effective for people who have a hard time pouring the medicine themselves without making a huge mess. Thank you very much."

For Constipation "My constipation caused a rectal fissure. The tear would reopen every time I had a bowel movement. I'd been on various stool softeners and laxatives trying to heal the fissure, but nothing worked until I started on MiraLAX. Now the fissure is healed, and I am pain-free. I'm so very thankful. Just wondering why I had to go to a colon specialist before I found out about this product. Why didn't the other doctor I went to suggest this product?"
