What is GaviLyte-N?

GaviLyte-N is a laxative solution that increases the amount of water in the intestinal tract to stimulate bowel movements. This medication also contains potassium, sodium, and other minerals to replace electrolytes that are passed from the body in the stool.

GaviLyte-N is used to clean the bowel before colonoscopy, a barium x-ray, or other intestinal procedures.

GaviLyte-N may also be used for purposes other than those listed in this medication guide.
