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.

 4  Idopathic Chronic Constipation Some bloating and gas pains. Effectivness seems to be diminishing the longer I use it. Initially could skip the dose for 2-3 days after two dosage days. Now have to take it every day. Resulting bowel movements are ribbony and messy. Was able to firm up bowel output by also taking one or two teaspoons of Psylium in water during the day. Miralax is most effective on me when taken in the morning. M 80 60 days

 3  Chronic constipation At first some rumbling in the tummy and sometimes hard to get to the bathroom in time, but I don't complain about that after my 79 years of little action from the intestines. I have been taking Miralax for about two years and it was a godsend after years and years of trouble with constipation. Now it doesn't seem to work nearly as well. I wonder if they have changed the formula or is it` just me. I hope someone can answer if they have changed the makeup of Miralax or not. F 79 2 years

 1  preparation for a colonoscopy I had shaking and chills. My heart raced. I lost all bowel control and spewed forth quarts, seemed like gallons, of nasty yellow liquid every few minutes over a period of about 5 hours. As I sat on the pot, I kept fading in and out of consciousness. As my doctor ordered, I took eight 8 ounce glasses of liquid with a capful of Miralax in each, one every 20 minutes. The effects started after I had taken them all, making it impossible to do anything at that point but tough it out. I thought of going to the emergency room, but the lack of bowel control made this seem impossible. F 79

 1  capsulendoscopypreparation severe stomach cramps, black stools, fainting I ;am 78 years old. This medication, Miralax, is too harsh, too rapidly acting, caused nausea, vomiting, fainting. The doctor was not all sympathetic to these symptoms. What can be done to alleviate these severe symptoms? Commom sense, as a retired nurse practictioner, tells me this is either too harsh, or too high a dosage for my age of 78 years. F 78 1 times

 5  Chronic constipation None I've had chronic constipation for 10 years. I've tried everything over the counter stool softeners and medications. My daughter who is a nurse came to visit me last month and I was terribly constipated, she recommended Miralax and I started on it that day and in 4 days I started going regular and have been regular every day since. I've never had a laxative that worked like this. F 76 1 months

 1  Constipation Activia had worked wonderfully as a regulator for me for some time, but I was headed for Europe and my Dr. had me substitute it for Miralax because the Activia required refrigeration and miralax didn't. I took ONE dose of miralax with prune juice and within about 2 hours, I had a terrible reaction - for about 2 days I had what I would call a "colon cleansing", felt terrible and couldn't take the trip to Europe. I am disgusted with this product. I am just so thankful that I didn't get on the plane before taking Miralax or I would have spent the entire 7 hour flight in the bathroom - I wouldn't recommend this product ever. F 76 1 days

 5  bowel resection after perforation No side effects For all of my life I had been as regular as clockwork...once a day, every morning. After a perforation during my first (botched) colonoscopy exam I required a bowel resection and started using Miralax. One cap every day. As the years went by I have been able to reduce this dosage down to 1/2 cap daily and currently 1/2 cap only a few times a week. My specialist (NOT the surgeon!) said I could use this product for as long as needed. Saved my (quality of) life F 75 5 years

 5  Chronic constipation + post surgery After constipation issues all my life, it was a relief to have predictable bowel movements. However, in the last 8 mo. I've had two uncontrollable, explosive "happenings". I've never thought about lowering the dosage, I'll consult with my MD. Just grateful something works. I've always been a water drinker, so that wasn't the issue re: constipation. I think IBS, Crohns, and lifestyle were more the problem. F 75 18 years

 2  colonoscopy prep My colonoscopy prep consisted of 10 oz magnesium citrate, then, 8.3 oz Miralax in 64 oz Gatorade and 4 dulcolax tablets. Prep worked well. Colonoscopy went well with removal of 2 non cancerous polyps. Within 4 hours post procedure I experienced severe abdominal cramps, nausea, vomiting. Went immediately to emergency room and was diagnosed with bacterial colitus. Prescribed drugs Metro... and Cipro... to take for 10 days. For next week, experienced extreme weakness, loss of appetite, dark urine. Stools continued loose but not watery. 15 days later my colon is still not operating properly, not removing water sufficiently and lacking any natural e coli, killed by drugs. My gastro dr. opined that he could not identify the cause of my "toxic shock" experience. He stated that the Miralax might have caused the problem. Don't know that I believe him, could have been bacteria introduced by the colonoscopy equipment. M 75 1 days
