Over time, they will become less efficient and more dependent on the laxative. According to the Mayo Clinic, prolonged use of Lansoyl jelly can result in a decrease in the amount of vitamins and nutrients the body absorbs 1. It is strongly advised to discontinue the use of any laxative after bowel movements have become regulated.
