Colace, aka Docusate, has been used for decades to help with constipation.
Too bad it does not work…
One in six US adults have constipation and many use over the counter products, such as colace. When studied in clinical trials however, colace is no better than placebo (fake) pills. https://goo.gl/3WhrBH.
Miralex (PEG) is a laxative that is safer for long term use when needed and can be added to any drink. It is preferred to stimulants like Milk of Magnesia for chronic help.
