Upsides
  • Safer than laxatives.
  • Available over-the-counter.
  • Safe to use in children as young as 2 years old.
  • 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.
Downsides
  • May take up to 5 days for the full effects to kick in.
  • Intended to be used only as a short-term solution for occasional constipation. Other options such as fiber supplements may be more useful for maintaining regular bowel movements.
  • 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.
