Is it safe to drink miralax (polyethylene glycol) when pregnant? Will it cure constipation?

Constipation: Change in bowel habits, either diarrhea or constipation can occur with pregnancy. Most critical to bowel function is eating regularly and following a careful diet. When constipation develops, increasing water intake and adding fiber (metamucil, citrucel, benefiber) is usually enough. If okay with your obgyn, MiraLAX (polyethylene glycol) is usually well tolerated and can help if fiber and water are insufficient. ...Read more

Is it safe to take both miralax (polyethylene glycol) and colace every day during pregnancy? Should I be concerned that both are category "c"? What are the risks if any?

Is it safe to take both miralax (polyethylene glycol) and colace every day during pregnancy? Should I be concerned that both are category "c"? What are the risks if any?

Good meds: These agents essentially stay within the gut and are minimally absorbed if at all, into the body. Since they don't reach the blood in any significant amount, they cannot have an effect on the fetus. Part of the category c label comes from not having enough research reports to move it into a safer listing. The cat c meds show no negative effects on baby. ...Read more

Am 17 weeks pregnant having severe constipation, is miralax (polyethylene glycol) safe to use during pregnancy?

Am 17 weeks pregnant having severe constipation, is miralax (polyethylene glycol) safe to use during pregnancy?

I prescribe it: There are many options for constipation in pregnancy. First involves making sure you are taking enough water and fiber in your diet. Metamucil or fibercon can be used in addition to natural sources of fiber. Colace twice daily often helps as well. But for those patients who don't see improvement on that regimen, either a dulcolax suppository or MiraLAX (polyethylene glycol) is the next thing I typically suggest. ...Read more

My wife is 10 wks pregnant and having severe constipation. Tried stool softeners and Metamucil. The dr recommended miralax (polyethylene glycol) but we read mixed info. Ok?

Yes: Miralax (polyethylene glycol) is fine. Most important, though, is drinking lots of water. The hormones of early pregnancy slow the bowel down, so constipation is a problem. It usually gets better in the second trimester, but then worse again in the late third. When the baby's head is taking up room in the pelvis. ...Read more

I really want to take my miralax (polyethylene glycol) dose down just by a little bit. Would that be safe?

Usa as needed: Miralax (polyethylene glycol) is primarily a wetting agent, that has a variable dose that depends more on your diet and bowel habits. Most can vary the dose up or down to reach a personal best dose. A full suggested dose may work for many, but double or half will work best for others. Getting into a habit of scheduled emptying 1-2x daily can often let you wean off the material altogether, but I would do so gradually. ...Read more

What's the concern?: Miralax (polyethylene glycol) is a generally safe, non-systemic lavage agent, intended to assist with laxation. Your voiced concern makes me question: for what symptoms has it been prescribed to you, what is the intended dose & duration of use, what have you tried before, what tests have been run prior to starting the product, what other symptoms do you have (weight loss, bleeding, pain), what's the underlying disease? ...Read more

Is it safe to give a 6 month miralax (polyethylene glycol)?

Yes: This was once a prescription product but the pediatric GI 's began using it in kids a decade or so ago & with its safe record it has become a mainstay of treatment for some. I don't use it first this young. Full strength prune or apple juice in quantities of an ounce or 2, 1 or more x/d will help most infants. If that has not helped in a month I work with moms on an individual plan with it. ...Read more

I'm using miralax (polyethylene glycol) and it says on the bottle not to use past a week, my provider told me it was safe to use every day. I need another opinion?

Generally it's safe: The makers of MiraLAX (polyethylene glycol) want to make sure you aren't using it because you have a serious underlying condition that is being masked by its use. If you've seen your doctor and they feel you are ok with it, then it is most likely fine. That said, it's way more healthy to have normal bms because you are eating lots of fruits/veggies, drinking water, exercising, etc than because you take miralax (polyethylene glycol). ...Read more

Yes: Miralax (polyethylene glycol) is probably the most commonly used medicine for constipation in pediatrics.

I would recommend discussing with your pediatrician the dosage, the length of expected treatment and when your doctor wishes to see your child back for a recheck. ...Read more

There should be: A "happy medium" between obstruction and diarrhea. Perhaps you should decrease the amount of Prune juice (which is the "variable" "dosae:) until you have soft stools with 'reasonable" frequency!
Hope this is helpful!

Does Miralax (polyethylene glycol) has risk for kids if takes one- two cups a day for few months? Is there any natural safe solution for constipation beside the Miralax (polyethylene glycol)?

Safe and a blessing: Chronic stool retention has been around as a problem for decades. We used to use flavored mineral oil which was messy and leached out vitamins. Mirilax came along and was tested in prescription form for years before proven so safe it went OTC. I have had kids who needed it for a year to straighten out their system. The most common reason for treatment failure is stopping it too soon. ...Read more
