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.
  • The combination of a laxative and stool softener might work better for people with constipation caused by medicines.
  • The laxative in Docusate/Senna was used over 3,500 years ago, so it's been around for a while.
  • Docusate/Senna is clinically proven to relieve constipation from a variety of causes.
  • One of the few laxative/stool-softener combinations that can be given to children 2 and older.
  • It may not work for everyone, but people felt it was worth the hassle.
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.
  • Most people felt that it's not the most effective laxative out there, but they could deal with the hassle and it worked pretty well.
  • Docusate/Senna can cause cramping or the feeling that you "have to go right now".
