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)

 4  chronic constipation due to meds sometimes gas I have had a constipation problem since childhood.This has been very helpful. Now that I have to take certain medications constipation has been worse. I just find it difficult to get appropriate dose and if I skip a dose it does not work right away. Sometimes go too much and other times small BMs. However, no taste and can mix with almost any liquid. Certainly better than constipation. Other than occasional gas no major side effects. I am in the health field and would recommend. Just realize that we are all individuals and dosages and side effects may vary. M 66

 3  Chronic constipation After 2 doses/day for 2 days and 1 dose per day for two days, I stopped taking it. It worked but way too much bloating with lots of gas and pain lasting for hours. I stopped taking miralax two years ago because of too many side effects. Why is it always advertised as being gentle with ni bloating, no gas, no pain. Simply not true (for me). Maybe for people with IBS, all laxatives cause problems. Oddly enough, I find the side effects of sennokot less severe than miralax F 66 4 days

 5  colitis I have to take this med when I first get up before I eat or it will cause cramping. I've also learned not to be careless about measuring the 17 gms or I will get dirrahea. I take it once a day. I for one am grateful for it because I can't take fiber supplements due to an allergy to wheat. I was in a lot of pain, enough to make me break out in cold sweats and vomit. now I'm regular and I don't have to hurt. F 65 2 years

 4  constipation due to B/P meds Some gas at times Have been satisfied with this product. I have noticed that I am having fluid retention that I've NEVER had before in ankles, legs & hands. Has anyone else had this problem? I hope it isn't the Miralax because it is helping so much with constipation. Please post an answer concerning this. F 65 3 months

 4  constipsation Doc said hemmoroids would get better. Gradually they have gotten much worse. They used to be a minor nuisance. If you have any comments on this, please post. Really works well for me at 1/3 the rec dosage. If not for the hemmoroids getting worse, life would be excellent. M 65 1 days

 1  chronic constipation alternating bowel movements, often with little warning, and sometimes without stool but with expulsion of large quantities of bloody mucus, abdominal pain, bloating, gas. Symptoms continued for over a week after I stopped taking it. I started on Amitiza instead, first the 8 mg dose twice daily, and then 24 mg dose twice daily. It did nothing -- did not relieve my constipation at all. This was a nightmare. I took the Walgreen's version, called SmoothLax, but it contained only polyethylene glycol 3350 in "original prescription strength." F 65 7 days

 1  Colonoscopy prep Took the prep in the 2 hour span. Severe shaking & chills began in first hour. Blood pressure soared as well as heart rate after the second hour. Felt as if I was overdosing because I was not hearing well. Legs were tingling. Thought I was having a heart attack or going into shock. Called 911 and stayed overnight and the next day on a saline drip--24 hours to be exact. Would possibly have died if I had been alone. I am 5'3' and 115 lbs. My husband is 240lbs. We both were given the same instructions with the same dosage for our preps. This does not make sense! Doctors need to be more diligent about this prep. They are not listening to their patients' complaints concerning this drug. I am a runner and exercise 3-4 times a week. I am very fit and have a healthy diet. I am on no meds. This should not be happening. Do not take this product. This was the most frightening experience of my life and I am a cancer survivor! F 65 1 days

 5  chronic constipation Took a couple of days to start working. Really smelly gas just before bowel movement, and really soft stools. Bad hemeroids so hard to clean rectal area. I've been taking this for over three years, following a colonoscopy and recommended by my gastroenterologist. After years of constipation, this has been a Godsend. I used to take six stool softeners, metamucil, rutin, and was still constipated half the time. Would go days without a movement. I'll gladly put up with a little messiness for regular bowels.

 5  IBS Miralax has been miraculous for easy my constant constipation. It works unlike any other laxative. There are no cramps or sudden urges or embarrassing need to get to the rest room. However, I have noticed a change in the past six months. I have been getting gas and bloating and air in my stomach. I have never experienced this before. I think that the manufacturer has changed the formula. It is not a prescription, so there would be no announcement that the ingredients have changed. I am sure something has changed. I still continue to take Miralax because nothing else works as well. F 64 8 years

 4  Colonoscopy Prep Consumed 238 gram size of Miralax, 4 Ducolax pills, and 64oz of Gatoraid If you mix the Miralax really well with the Gatorade, you won't know Miralax is in your drink. It took me 2 hours to drink it, and about an hour later, I felt the impact. It got the job done. F 64 1 days

Patient History
 1  colonoscopy prep chills, very loose bowel movements - caused accident during night; 4 days post prep had accident - poop in pants for first time in adult life. NEVER AGAIN. In past did Halflytely which was better without side effects. Agree with commenter that doctors should ADJUST DOSE by weight. A woman weighing 130 should not get same dose as man of 220 lbs - this should be common sense. F 64 1 days

 5  Constipation & IBS At times stool consistency was very sticky & difficult to pass & adequately clean. My husband and I both found varying the quantity & frequency of use helped maintain quality and quantity of stools & lead to more frequent complete evacuation. F 63 5 years

 5  Chronic constipation None My doctor recommended Miralax as a last resort, since stool softeners, drinking additional water and watching my diet did not help. Began working after 4 days with multiple, soft but not loose stools, then cut back to movements once or twice a day only. I take it every morning, a full capful, and have experienced absolutely no side-effects. My stools are "comfortable" now and reasonably "regular," which is an outstanding improvement for me. To the person concerned over taking it once a week, my experience would indicate that daily use does not "overdo" it. Everyone's system is different, however, so you may need to "experiment" to determine your specific optimum usage. F 63 1 months

 5  constipation/diverticulitis None After years of severe abdominal pain attacks, I was diagnosed with Diverticulitis. When I had these attacks, I would try all kinds of fiber supplements to move matter through my system. Each had side effects - UNTIL, prior to surgery, the surgeon recommended Miralax, along with eliminating all seeds & nuts from my diet. She said that Miralax is gentle & has no side effects, which has proven absolutely true for me. It feels wonderful to have my system working normally again, and because of Miralax & eliminating seeds & nuts from my diet, I've been spared surgery! F 63 1 years
