"I have Irritable Bowel Syndrome with constipation. Before taking Miralax, I would go days without a bowel movement. Nothing but misery. After talking with my doctor about Miralax, she suggested that I take it every day for one year. Upon doing so, I had a bowel movement and sometimes several every day. I got to the point that I sometimes was losing control so started cutting back on how many days I took Miralax. I now take it 2-3 times a week, usually have a bowel movement daily and have control of the situation."

"I had been suffering from severe constipation that couldn't be cured even with laxatives for 2 weeks until my doctor recommended Miralax. I took it with no real progress for 3 days, but on the 4th day, I finally started having normal bowel movements! I did not experience any side effects whatsoever as you do with laxatives. (No diarrhea, gas, bloating, sudden urgency, etc.). I finally had complete relief! Also, I mixed Miralax with cranberry juice. It had virtually no taste and dissolves completely. I highly recommend this to anyone suffering from constipation."

"Some parts of this review may be TMI - so you are forewarned - but I am hoping to help anyone in my shoes. I have had constipation issues since I was 18 (40 now) lately, it has been getting so severe that I ended up in the ER with severely impacted stool (twice). That was a nightmare. I don't like prescription medication so dr told me to try Miralax once a day. Man, this has been a life saver. If I notice my stools are too soft, I will skip the next day and take it the day after. I mix a capful with Gatorade, I let it sit in the fridge for about half hour and when I see it's all dissolved, down the hatch it goes. No taste and works wonders!"

"I recently had a laparoscopic hysterectomy. As some of you may know, anesthesia from surgery can cause the bowels to basically just stop moving. Add to this the trauma of surgery in a nearby region, combined with taking narcotics, and I was MISERABLE. It took 3 days for it to work, but when it did it was a major miracle. I did not realize constipation could be so bad you'd consider that you might DIE. Miralax not only works, but it does not give you the horrible sick cramps you get with stimulant laxatives. Just the best ever."

"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."

"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 :)"

"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."

"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."

"I’ve used miralax previously with success. Most recently after a number of issues, 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."

"I had used other laxatives to regulate my digestive system and many of the other laxatives gave me awful side effects such as nausea, excruciating cramping and others, miralax worked very well without the side effects the other meds had."

"Heart medication has caused acute constipation. When I take miralax, I go get BMs, but the effect is that I am extremely gasey and each time gas passes, small amount of poop comes out. It keeps me running to the bathroom and holding gas day and night. Sometimes I get to where I cannot stand the constipation any longer and try the miralax again... same horrible results and never feel cleaned out."

"So for me I am on a few medications that cause constipation. I also am on a stool softener and a pill called movantic to help me use bathroom. I recently had a colonoscopy and everything looked fine just struggling with severe constipation. There's times when I haven't gone for 2 weeks. I messaged my doctor and asked what to do and he told me to add miralax daily. I know this sounds weird but I just had the best bowel movement I think I have ever had. It was like they described self-serve ice cream and it was a lot! I always drink lots of water and I'm on two other medications for this reason. So adding miralax has made a huge difference! I am very happy with this light laxative. It's safe to use everyday. Also you can play around with the dose depending on what your level of constipation looks like. Mine being severe I've been taking it everyday for a week and I finally had about movement. After having a really really bad day last week of not being able to go I was in such pain!"

"I'm 52 and healthy. Got completely blocked up after eating too much cereal with psyllium husk (even with drinking multiple gallons of water!) and felt like I had a boulder in my colon for a few days. I was going to have my wife take me to the doctor's office or the emergency room for help but then I remembered that after a surgical procedure several years ago, my Mom took antibiotics that did the same to her and her doctor gave her Miralax to solve the problem. So my wife went to the store and got some for me and I immediately took a full dose (17g) with half a gallon of water and a small bottle of Gatorade Zero. Within an hour I could feel (and hear) it beginning to soften the mass inside me. And about 18 hours (and another half gallon of water) after taking that single dose, the problem was a memory with minimal pain in its solution. And though I hope to never have to use it again, I will be keeping a bottle of this stuff in my medicine cabinet...just in case. Recommended. Good luck!"

"I've been using generic Miralax 2-3x a day for years for drug-induced constipation. The problem was that I was either running to the bathroom or in pain from constipation. 2x a day could be too much but I never knew. Finally I decided to get an appt with a gastroenterologist and she suggested that I also dose 2x daily with Metamucil. The combo gives me normal poops most of the time. I really feel it if I get busy and forget. Now unless I feel impacted I take Miralax 2x a day and fiber 2x a day. The combo is amazing."

"My first day of use of MiraLAX I had a lot of passing gas and one small movement. My second day a small movement but cramping and bloating feelings began. At night the nausea and cramping stopped me from sleeping. Third day still some cramping and fullness. No movement just cramping and bloating. Going back to the urgent care for instructions. Will not take Miramax again."

"I’m a healthy 24 year old female. Usually very regular. But after a recent round of antibiotics I was suddenly constipated for about 9 days. I tried everything. Metamucil. Prune juice. Dulcolax. I finally decided to try Miralax. The first time I took a capful, the recommended dosage. It did nothing. Then a couple days later I upped the dosage. I poured half the bottle into about 8 oz of prune juice and chugged it. I didn’t feel anything until 3 1/2 hours later (around 10:30 pm) When I tell yall BUBBLE. GUTS. The most sudden and abrupt bout of gas, gurgling, cramping, and farting. I felt like I was going to poop my pants. I ran to the bathroom. Everything in my stomach was melted and pouring out of me. Not all liquid, just very very soft stool coming out in a steady stream. For the rest of the night and into today (it’s 3 pm) I’m battling diarrhea. It’s not as bad now and the cramping has stopped. But I feel so much lighter and relieved."
