Helps get things moving.

Miralax (Polyethylene Glycol) provides effective relief of constipation without "cramping" your style.

4.0/ 5 average rating with 226 reviewsforMiralax
Relieves occasional constipation.

Dok-plus (docusate and senna) is a good choice to help relieve constipation, but should only be used occasionally.

Upsides
  • Miralax is the most recommended laxative by pharmacists and doctors.
  • Most people felt it was worth the hassle.
  • It's gluten and sugar free.
  • It causes little to no cramping, bloating, gas, or feelings like you "have to go right now" compared to some other medicines to treat constipation.
  • Works differently than other over-the-counter laxatives so it's a great alternative if other medicines haven't worked.
  • This medicine is commonly used to help relieve occasional constipation.
  • Generally tolerable with few side effects.
  • There are many different formulations available over the counter, including generic.
  • Can take this medicine once a day.
Downsides
  • You have to dissolve Miralax in a beverage and drink it versus taking a pill.
  • It's not for children 16 years or younger.
  • Miralax doesn't work overnight. It can take up to 2-4 days to have a bowel movement.
  • It's not recommended that you take it for more than a week, so it you haven't had any success, you'll need to call your doctor for other laxative options.
  • Doesn't offer immediate relief and is not meant for regular use.
  • Need to remember to separate your other medicines with Dok-plus (docusate and senna).
