MIRALAX  (POLYETHYLENE GLYCOL 3350):  This medication is used to treat occasional constipation. It works by holding water in the stool to soften the stool and increases the number of bowel movements. It is known as an osmotic-type laxative. This medication is also available without a prescription. If you are taking this medication for self-treatment, it is important to read the manufacturer's package instructions carefully so you know when to consult your doctor or pharmacist. (See also Precautions.)    (Sources: U.S. Centers for Medicare Services, FDA)

 3  IBS w/constipation loose stool, gassy, bloating, I have not been on Mirlax that long, just a couple of days, but can't seem to time when the best time of day is to take it. I am afraid to take it at night for fear of being up all night, and in the day I worry because I will be out of the house. I am also on Amitiza, which I see no comments on. I hope someone out there can tell me to keep up with it that it will get better, because right now, although my intestines are emptying, I just can't figure out when. There is no cramping, it is just now. I hope that it will regulate sooner than later. F 36 3 days

 2  constipation I had to leave work early because I could not make it to the bathroom. And for days when I would go pee and wipe I would notice I had leakage and didn’t even know it. So if you enjoy pooping your pants go ahead and use it. F 36 3 days

 5  life-long constipation some bloating, but still far more desirable than the side effects of chronic constipation. i recently injured my tailbone due to the constant straining resulting from constipation. i eat a high fiber diet and drink lots of water but have always had chronic constipation. miralax has been very reliable and effective since I got the dosage just right. the tailbone injury has now had a chance to heal. my gi doc advised me that I can take this forever without any long term effects, dependency or tolerance issues. far safer than most otc alternatives and I find it far more effective than anything else I've ever tried. this is how it was explained to me: the drug does not enter the blood stream and is not absorbed from the intestinal tract. it stays within the gut and pulls water into the intestine thereby increasing the volume and frequency of bowel movements. it is also FDA approved.

 4  constipation Excessive gas, gurgly stomach, and bloating. Miralax is an effective medicine for my chronic constipation. However, every time I use it, it takes 4 or 5 days to work. Currently I've been instructed by my doctor to take one capful every day for one month. I'm not sure how much longer I can stand the gas and bloating though. F 35 14 days
one capful 1X day

 3  Constipation The Miralax definitely helped my constipation, only had to take it 3 days. BUT, I have developed heart palpitations that are still going on 3 days after my last dose. Looked it up and it appears this can be a side effect. Please be wary and do NOT take more than directed (it can still happen with the recommended dose). M 35 3 days

 2  Constipation Thought I'd try something different other than Metamucil which helped me go 2-3x a week instead of 1-2x a week without. However, I told my doctor about it and she recommended miralax. Said I could take it doe the rest of my life daily if I wanted. But I tried it day 1 and my stomach got very cranky and gurgly and gassy. I went ahead and took it the second day also and had similar discomfort. The 3rd day I had a BM but the gas was so bad and the smell of my gas was super bad. Sulphuric smelling. I figured it would go away and maybe this was "cleaning" out my system and I needed to let it run it's course. So, I took Mirilax again the 3rd day but nothing changed. And maybe it's still too soon to tell, but the gas and bloating is too uncomfortable. I also have had intermittent bowel movements bc my stool is too soft and sometimes feels like I'm going to have a little diarrhea if I let out too much gas. So my liquidy and softer stools are not worth it to me. My stools were always normal previously, but didn't come very often within a week. I'll stick to Metamucil, fruits, and drinking water. I'm 6 days out now from when I initially started taking it and 2-3 days from my last dose. I'm still having smelly gas, bloating and stomach cramps... F 35 3 days

 1  Bowel prep rapid heart, sweating, dizziness, fluid retention, shortness of breath, impending doom feeling, ect. Worst thing I've ever taken and have experienced. I've had 3 hospital trips taking this medication. My Dr. kept insisting to just keep drinking it and I would see results. Meanwhile I almost died because my blood pressure dropped so low I could barley walk. I was so dizzy the room was spinning my heart rate was 160bpm and I'm still feeling the effects 3 days later. I can't eat because when I do it feels like my stomach is not digesting it. My stomach gets so insanely bloated and sore it's hard to breath. I have no idea why this medication is still the #1 bowel prep and for constipation. It needs to be off the market. It says right on the bottle do not take if you have IBS yet my gastro diagnosed me with IBS right before she prescribed miralax for me. Drs just do not care it's so sad. F 35 1 days

 5  Chronic Constipation The first day I had horrible cramps, but that was only because I was so backed up. My bowel movements were about once every two weeks, and they were HUGE (I mean in mass) and usually caused bleeding. When I rarely had the urge to have a movement, it was painful. Very painful. Miralax has erased that, I go every day with no pain. I have had no cramps or any bad side effect. F 34 1.5 years

 5  Constipation None. I have suffered from chronic constipation for years. I recently discontinued the use of stimulant laxatives because I know that they exacerbate the problem. After about three days of use, I started to have regular BMs that were well-formed, but small. The BMs got larger and more frequent. Yesterday, I have five large BMs! I don't eat that much and am very thin, healthy, and active (run marathons)...I must have been really "stopped up." It feels good to get all that stuff out of my system. I figure it will be about a week before my intestines "catch up" to eliminate that day's waste. Highly recommended. A dream come true. F 34 14 days

 5  anal fissure i experienced no side effects at all. was in extreme pain for almost 3 weeks. a friend recommended i try it. fiber supplements and stool softener pills were not helping. after taking miralax for 2 days, i had results and after 5 days, i am feeling almost 100 % normal again. no side effects and it did not increase BM's for me.. just made them much more comfortable and gave my body time to heal.

 5  SEVERE Constipation A little extra gas, slight nausea (right after taking dose), strong urgency to have BM (though NO cramping, pain, etc...) THIS MEDICINE IS A MIRACLE!!!!!!!!!!! This medication has been an ABSOLUTE miracle in my life! I have battled constipation for about the past 10 yrs to the point that I would only have a BM once a month with the help of strong laxatives. It got to the point that laxatives didn't help anymore and I would only release water. I took Miralax for 3-4 days before it worked and upped my dosage to twice a day. I have gone to the bathroom everday since beginning this. I actually lost about 10 lbs! I know I was REALLY close to getting seriously ill. I cannot say enough about this medication. Just be patient and adjust your dosage at first to find what works for you. It is truly amazing!!! F 34 3 weeks

 4  Colonoscopy Prep Slight chills in first half hour, covered myself in a blanket and it passed. Otherwise, none. Very well tolerated, no vomiting or scary side effects. Had started a low fiber diet 2 days prior and liquids that day plus 4 Dulcolax. Mixed the Miralax with 64 oz Gatorade and drank over 2 hours. Started to work after 90 minutes with no loss of control, continued throughout evening. Was able to sleep in spite of getting up to go a few times. M 34 1 days

 4  Constipation None I had a back strain/sprain, so the effort of passing a BM was quite painful. I'm not sure if I was actually constipated per se, but my stool was definitely not soft, and it was very difficult to muster up enough strength to do the deed without causing severe back pain & spasms (which makes it very hard to relax the sphincter). So I decided to try Miralax. The next day I passed with little effort, so I'm satisfied with the results. As for the people advocating "natural remedies," keep in mind that most illegal drugs and many poisons are natural too -- doesn't make them safe or healthy. People may be hypersensitive to polyethelene glycol, but others are allergic to penicillin (which is produced by the "natural" penicillium fungus). Nature doesn't set out to create remedies; natural substances simply happen to work for certain purposes from time to time. To avoid something simply because it's man-made is needlessly limiting one's options. M 34 1 days
