ClearLax (polyethylene glycol 3350) for Constipation "I've been taking Clearlax 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 same ingredients as Miralax. Anyway, my constipation was driving me crazy and 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. "

MiraLAX (polyethylene glycol 3350) 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."

MiraLAX (polyethylene glycol 3350) for Constipation "I am 14 years old and was taking an anti-inflammatory medicine as well as a prescription pain killer for my kidney stone that I have. Those medicines made me constipated, and while I was at Childrens ER, my nurse practitioner prescribed me MiraLax. I was skeptical, and afraid that it would counteract with my other medications. She assured me that it would be okay. Did you know, you don't have to take it just once a day? I took 2 doses at once with 16 ounces of water, and a couple of hours later, I finally had a bowel movement. Overall this medication is really phenomenal. The only bad thing about it, is that it causes gas and nausea. Other than that, I'd say this is the best constipation reliever for all ages out there!"

MiraLAX (polyethylene glycol 3350) for Constipation "The Mirlax 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 puduct for many years... could have a more 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 Crystal light company's companies idea. Yet is still effective for people who have a hard time pouring the medicine themselves without making huge mess. Thank you very much."

MiraLAX (polyethylene glycol 3350) 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."

MiraLAX (polyethylene glycol 3350) for Constipation, Acute "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."

MiraLAX (polyethylene glycol 3350) for Constipation "I am 20 years old and have had problems with bowel movements since I've been potty trained. I've usually had one extreme to the other but going to the bathroom was never easy for me. I finally went to see my doctor to see if there was anything we could do about this. Throughout my childhood I've been on different medications, but nothing helped. Now finding out I'm lactose intolerant doesn't help either). She prescribed me Miralax and I have to say when I use it correctly (that is taking it everyday and drinking enough liquids with it) it works wonders. I no longer get stomach cramps or gas. "

MiraLAX (polyethylene glycol 3350) for Constipation "My constipation caused a rectal fissure. The tear would re-open 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. 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?"

MiraLAX (polyethylene glycol 3350) for Constipation "I'm a 24yr old that recently had back surgery. They had me on tons of medications, of course, one being a stool softener because a lot of medicine intake tends to make one constipated. Well, the stool softer that I had to take twice daily didn't work one bit. I got so bloated and had some serious stomach pains, that I finally decided to try a laxative (never having tried one before, I was alittle intimidated). Now, before injuring myself and having the surgery, my BMs were extremely regular: once a day. After that, I was rarely going. When I tried Miralax it worked within the hour of drinking it in some ginger ale! I felt SO MUCH BETTER! It makes your stomach gurgle and gives slight cramps, but worth it in the long run!"

MiraLAX (polyethylene glycol 3350) 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."

MiraLAX (polyethylene glycol 3350) for Constipation "After several weeks of constipation (not that I was ever regular), my doctor had me try this. Ironically I'd just picked up a package of it. I took it around 5pm and had a bowel movement at 9am the following morning. I want several times after that. There was lots of tummy grumbling but no cramps to speak of. I did feel "off" the rest of the day but I believe that was due to a fever with the cold I was coming down with. Would definitely use this again."

MiraLAX (polyethylene glycol 3350) for Constipation "Not long after a colonoscopy my movements seemed off. I thought it was no biggie -- until things basically shut down. I never knew that constipation could be so tough and depressing and scary. It was like my body was rebelling and not obeying orders. Got a box of MiraLax packets and took my first daily dose around 6PM, hoping that it would work and not take three days. Within a few hours it seemed like something was happening. There was some gurgling and expelled gas. Normally that might be bad, but under the circumstances it was a hopeful sign. Around 1AM I finally went and it was painful and not fun--but what a relief! Have had two more movements since then (its the next day) and each one has been easier than the last. So just one dose and seemingly back to normal! I can't imagine what a chronic case of this must be like.... I almost feel guilty that my cure went so well. Anyway there's no bad taste to it and I'm glad it worked. Worth a try, I think."

MiraLAX (polyethylene glycol 3350) for Constipation "I have always had constipation all my adult life. I had a C section at the age of 20 and at 25 I had a partial hysterectomy which was the start of the constipation. I used laxatives and enemas for years until laxatives made me so sick I just used enemas daily. Between ages 25 to 32 I had 4 female surgeries including the partial hysterectomy. During all this I was also diagnosed with spastic colon and anxiety issues. I have done the milk of magnesia, magnesium citrate liquid, and enemas all these years. Now I take 2 capfuls daily of the Miralax powder from behind the counter and most days have 2 or 3 bowel movements. Occasionally I do use milk of magnesia when I feel I am not emptying good but Miralax is less harsh."

MiraLAX (polyethylene glycol 3350) for Constipation "I’ve been constipated for the last 5 years after 2 major surgeries on my brain/spine due to brain cancer which left me paralyzed. My dr finally prescribed miralax after other laxatives were not working. I’m really hoping this works as at the moment I only have a bowel movement once every 1-2 weeks. As of today it’s actually been 3 weeks and 2 days since I’ve had a BM. Just took this medication an hour ago and I already have diarrhea. I hope this doesn’t last long. I just want a normal BM for once "

MiraLAX (polyethylene glycol 3350) for Constipation "I had miralax after a surgery last week. I took it once daily, it didn't produce a bowel movement for 6 days but when it did the stool was soft and came out without straining which is good because I had open heart surgery. I will continue to take it until I am off of the pain medication which last time I was on it caused a horrendously painful softball size poop."

MiraLAX (polyethylene glycol 3350) for Constipation "I have chronic constipation, so the doctor told me to take it daily with the drink of choice. Before you read: don't get me wrong. It does a wonderful job. Effortless, painless, easy, quick bowel movements and relief within 24 hours. It's very effective. But taking it is a pain! Every time I take it, it tastes so bad (the flavorless one) no matter what drink I put it in that I have to drink it holding my breath with a straw over the sink in case I vomit and rinse my mouth out with soap afterwards. It's actually conditioned me to stop drinking some beverages because the taste reminds me of when I mixed it with miralax. I gag so badly after taking it. The nausea and burping from it usually lasts for 2 hours after I take it and I have trouble keeping it down and not vomiting from the taste. I just can't understand how so many people like taking this stuff. Disgusting! I hate it so much. I detest it from the bottom of my soul."

MiraLAX (polyethylene glycol 3350) for Constipation "I hadn't had a BM in over a week and took this and I was able to go within a few hours. Not sure if it really worked or if it was just from drinking more water but I think Miralax helped a little! Will use again if needed!"

MiraLAX (polyethylene glycol 3350) for Constipation "I am on my fourth day and still no bowel motion. Each time I took at night an hour before bedtime with water and it's amazing because there really isn't a taste at all. You would never know anything was added to the water. Just make sure you stir it so the water is pretty clear to keep it tasteless. I do have to say over the last 4 days I haven't had any bloating or gas."

MiraLAX (polyethylene glycol 3350) for Constipation "After taking a new medication for 10 days with no problem, once I titrated my dose to twice what I'd been taking, I ceased to poop. No poop other than a few "rabbit turds" here and there, for 6 days. On the 4th day of no poop, I took a dose of Miralax. On the 5th day, I took a dose in the AM and one in the PM, at bedtime. Same thing on the 6th day. Finally, I'd had enough waiting. I did the Dulculax/Miralax Colon Cleanse for Colonoscopy that is listed on many medical facility websites. I chose one with 4 tablets of Dulculax, followed a few hrs later by 8.3oz (approximately 14 doses) of Miralax dissolved into 64oz of Gatorade. It took 6 hrs after taking the Dulculax/nearly 2.5 hrs in of drinking the drink, for it to finally kick in. Whew!"

MiraLAX (polyethylene glycol 3350) for Constipation "I am constipated due to 6 auto-immune diseases and all the medications I have to take. It was first time I ever needed this type of medication. I have a high tolerance level but something told me to try a half dose. I can say it 100% worked and worked too well, quick too. I would make sure I have a night with the only plan is to take care of myself."

MiraLAX (polyethylene glycol 3350) for Constipation "I have an issue of constipation due to radiation treatment 25 years ago. I used to have ‘sticky poop’ which was difficult to expel, and after a few days I would have horrible stomach pain, and explosive diarrhea. I took a stool softener for about 4 years, which helped until recently. I started Miralax 4 days ago. I have lots of gas, but no pain. I have 2-4 small stools a day. I will continue taking it for awhile and see if things improve."
