Description

MiraLAX is a polyethylene glycol (PEG 3350) laxative powder made for providing gentle constipation relief. Unlike some laxatives which stimulate the nerves, MiraLAX is a non stimulant osmotic laxative, working naturally with the water in your body to hydrate, soften, and ease stool through the colon gently. Since going on the market in 2007, MiraLAX has been the 1 Physician Recommended OTC brand of laxative. It relieves occasional constipation without causing harsh side effects like cramping, bloating, sudden urgency, and gas. MiraLAX is a gentle laxative designed to relieve occasional constipation and presents no risk of product dependence. Constipation can be caused by lifestyle factors such as stress, diet, travel, medications, and lack of exercise. It can be defined by fewer than normal bowel movements, difficulty passing stool and abdominal bloating. To use, fill bottle cap to the indicated line (white section in cap) and pour into 4 to 8 ounces of hot or cold beverage including but not limited to coffee, tea, juice, milk and more. Mix until the powder is fully dissolved, then drink. Plus, MiraLAX has no added taste or grit. MiraLAX generally produces a bowel movement in 1-3 days.

  • Great Product- all positive
Item form: Powder Size: 26.9 Ounce (Pack of 1)
I Use daily because I use Zepbound. Stomach pain gone. No constipation. Surprised to hear other say it has a bad taste- to me it has absolutely no flavor. I mix it with water and it tastes like water. The side effect of GLP's of frozen stomach scared me but it's not an issue with using Miralax

  • Gentle & effective
Item form: Powder Size: 26.9 Ounce (Pack of 1)
MiraLAX works great! It’s gentle, tasteless, and easy to mix into any drink. I noticed results within a day or two without cramps or urgency. It’s perfect for occasional constipation and doesn’t cause discomfort like some other products. Definitely a reliable option to keep on hand.

  • Great Price and Gently Effective
Item form: Powder Size: 26.9 Ounce (Pack of 1)
Works gently and effectively overnight. Strongly recommend for chemo patients day before, day of, and day after each treatment. Made a world of difference! Only wish I'd known to do this for the first round. No taste; mix with water or juice. My GI prescribes this for colonoscopy prep -- far less aggressive than the pharmaceutical colon prep. But, for that, you use a lot more to clear completely so ask your GI about proper dosage for that purpose. I've always found best price for this by far on Amazon. ... show more

  • Great product that works.
Item form: Powder Size: 26.9 Ounce (Pack of 1)
We put 2 teaspoons in our coffee every morning, and this helps us with our constipation problems. It just puts water in your bowels, so it's easier to go. Sorry to be specific, but if you suffer from constipation, you will not mind the description.

  • Gentle with no discomfort.
Item form: Powder Size: 26.9 Ounce (Pack of 1)
Miralax is easy to consume mixed in water. There is no disgusting taste. It is very beneficial if used regularly. Our doctor recommended it due to our age (80) and irregularities. Miralax is a staple in our house. Amazon.com has the large size and fast delivery.

Item form: Powder Size: 26.9 Ounce (Pack of 1)
I have had digestive issues and constipation for years. Miralax works well and consistently to help relieve. With doctor recommendation, I take 1.5-2 capfuls at night and have relief in the morning. It does cause some gurgling and movement, so it's best to take close to bed time to avoid feeling them. It's flavorless and can be mixed in almost any beverage, but recommend drinking it cold. ... show more
