Upsides
  • Safer than laxatives.
  • Available over-the-counter.
  • Safe to use in children as young as 2 years old.
  • 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
  • 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.
  • 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".
