HalfLytely Bowel Prep Kit

HalfLytely® and Bisacodyl (polyethylene glycol electrolyte solution and bisacodyl) is a prescription laxative given to people before they have a colonoscopy. It is used to help prep the bowel. The HalfLytely and Bisacodyl kit comes with one bisacodyl tablet and a jug of HalfLytely powder (to be dissolved in water before use). Normally, the bisacodyl tablet is taken first, and the HalfLytely solution is started after the first bowel movement, or six hours later (whichever comes first).
HalfLytely is an osmotic laxative, which works by drawing water into the colon, softening the stool, and causing watery bowel movements. Bisacodyl is a stimulant laxative, which stimulates the smooth muscle of the intestines, causing the muscle to contract more often and produce frequent bowel movements.
The bowels must be completely empty before the colonoscopy so that your healthcare provider can look for causes of unexplained changes in bowel habits. Any stool inside the colon may hide important findings.
