For Constipation "I had surgery that went bad leaving my system kinked. This caused me to have nothing but problems with straining and constipation for several years now. I am so happy to be able to use something that makes me feel normal again."

For Bowel Preparation "I wonder if people recounting stories with vomiting and terrible cramping are also using the Miralax prep with Dulcolax, which can be known to cause these issues. Been prescribed Miralax ONLY prep (no Dulcolax or other laxatives) now twice: once for colonoscopy, once for abdominal surgery. Both times it is the easiest prep I have ever done, as someone who has had done 3 colonoscopies prior and had to take other prep. I, like many of you, am in my 20s and still have an intense fear of vomiting. There is absolutely no nausea for me taking the Miralax-only prep. 14 caps in 64oz, so a LOT of liquid, which helps as it draws water to the bowel and cleans you out. I was never advised to do split prep, so all in under two hrs. When mixed with Gatorade, pretty easy to get down, not the best tasting but a breeze in comparison to other colonoscopy preps I’ve had to do. No cramping or pain, the only discomfort I feel is the bloating and fullness from the amount of liquid consumed!"

For Constipation "Last year I had constipation really bad. I was going to the doctor many times. Then my doctor recommended MiraLAX. I took it for a while and after I got normal again my doctor said I could stop. I was going regular, now I haven't been in 6 days and have been using MiraLAX for 3 (today's the 3rd.) It hasn't worked yet, but I'm hopeful it will!"

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 7pm 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 Constipation, Acute "I suffer from Syringomyelia. This is a condition that severely effects your Nervous System. The stools that my Digestive Process produces kind of changes 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 Bowel Preparation "I have always used miralax, plain with water, I just drink and get it over with. The dulcolax tabs work too so I don't ever have problems, but the magnesium citrate 6 hours before procedure, for me, is the worst. That 10 ounces of bitter salt water taste takes forever to finish - I'm already clean and still have to drink it. I tried Moviprep and pain, stomach cramps were awful. But with colon cancer years ago, I'm grateful each time colonoscopy is fine and a little nite of miralax is nothing."

For Constipation "I have constipation due to irritable bowel syndrome. After using many other laxatives that helped for awhile, 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 Bowel Preparation "I used this for my first colonoscopy prep this past week. I was so happy with the experience after hearing horror stories. I followed a low residue diet for four days then a clear liquid day. Mixing the miralax in Gatorade was tasteless and very easy to drink. I was able to do a split prep so even the volume I had to drink was tolerable. I had no cramping, no pain, no nausea. My doctor rated my prep as “excellent”. Would highly recommend this prep approach."

For Constipation "Been constipated for years and only have a bowel movement once ever 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 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 "I have chronic constipation due to medications mainly my pain medications and I take miralax on occasion and it works but for me 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."

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, saline's, 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 "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 methodone and my bowel movements aren't nearly as painful but still give me problems. After taking miralax my bowels motions would come out with absolutely no pain but if you don't do it everyday it will keep happening"

For Constipation "I have taken Miralax since I was 3 years old due to a medical condition. The product does what it should, but after about 3 years it acquired a flavor that I can't stand. I mix it with other drinks and over time it ruins those drinks for me also. If you can get past the flavor it is a miracle product."

For Constipation "I was prescribed Miralax in the ER. I have been in HORRIBLE pain since Tuesday. I've taken Miralax since Wednesday and haven't had a bowel motion since. This product severely constipated me. The opposite of what its supposed to do. I am STILL in pain and I was normally regular. Not anymore. "

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 Bowel Preparation "I came on here to read reviews because I wanted to know what other people's experience was with this colonoscopy prep. I got so scared by reading some of these reviews that I built up a crazy amount of anxiety about my entire procedure. Obviously everyone will have their own experience. A colonoscopy prep is designed to make you poop a lot. I had ZERO bad side effects. In fact this prep was a pretty gentle one. Yes, I did have a sore butt but that comes with any colonoscopy prep. Don't let the negative reviews scare you. I took 4 ducolax and then drank the Miralax mixed in Gatorade. I did 8oz every 15 min until I finished the entire mixture the evening before. In the morning I only had to drink 32oz. I mixed that in water. It did have a very slight taste in water but it wasn't bad. I did prefer it in Gatorade but it was a lot of Gatorade to drink the night before. Anyway, all went very well. No bad side effects. I was a little cold but seriously nothing unbearable AT ALL! Good prep."

For Bowel Preparation "Rare side effect (high blood pressure spike) encountered: My doctor recommended that I use Miralax to prep for my colonoscopy. The instructions were to take 8.3oz (roughly 15 doses) the day before and then another 4 doses four hours before the procedure. Everything went as expected until I got to the appointment and as they were getting me checked in and ready for the procedure discovered I had dangerously high blood pressure (I.e. over 200/100). I wasn’t nervous about the procedure and had just had my BP checked a week earlier and it was around 150/80, still not the best, but nowhere near where it was after my prep. The only thing that had changed between the lower reading and the higher one was the colon prep with Miralax. WebMD lists it as a rare side effect, so likely it happened to be one of the rare cases. I wanted to share in case anyone else runs into this and can’t figure out why their BP went sky-high after using a high dosage of MiraLax."

For Bowel Preparation "First colonoscopy for me and I was really sweating this prep. I decided against the pills, and chose the MiraLAX/Dulcolax prep. Did tons of research. For 5 days prior to the 1-day liquid diet, I went on a low residue diet and started drinking coconut water and Body Armor (not gatorade). I'm certain this helped!! Took the dulcolax and although not prescribed, I also took a dramamine and a gas-x. I did the split-dose and started drinking the first 32 oz. mixture the night before (with BodyArmor, on ice with a straw, 8 oz. every 15-20 mins.) , and also drank chicken bone broth and coconut water in between. A little over an hour later, the games began. 4-1/2 hrs. later, I felt like I could relax. Slept like a baby. I had no cramping and only slight discomfort. Next morning, same. You will want to stay close to the bathroom! You won't be able to hold it. Doc said clean as a whistle, so I will definitely do this prep again."

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 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 8:30am 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 "I've been taking MiraLax, as my mom tells me, ever since I switched to formula. I'm not a good eater so I'm always constipated. However, MiraLax works pretty much all the time. It would get a 10 except that it failed today. I took my usual dosage and I was still constipated. I guess it's because I've been taking it my entire life."

For Constipation "I take Miralax every day and have for about six months, per my doctor. I have an abdominal hernia, inoperable. My complaint is your new POUR SPOUT. I HATE IT WITH A PASSION. My last purchase did not have that feature and it was a real pleasure. Why in the world did you think that would be a good addition to the bottle? I wish you would stop that and go back to just the regular bottle. Miralax is my God send. I have a lot of problems with my bowels and this helps me greatly. I have recommended Miralax to my friends. Surprisingly, some already use it. That is my say for today. Sally Wiese"

For Bowel Preparation "This is the second time I took Miralax and had an allergic reaction to it. I was on steroids before my last colonoscopy so it did not bother me. The last time I took Miralax the Dr. could barely see, almost like a poop storm without wipers. Not good prep for me. So I have to reschedule to get another polyp out. And don't ever use the word constipation or they will place you on a 3 day no food regiment. Then Draino."
