As part of a group of medications called osmotic laxatives, GlycoLax™ (polyethylene glycol 3350) can help treat constipation. Although GlycoLax is no longer manufactured, several generic versions are still available.
This product works to treat constipation by drawing water into the colon, softening the stool, and increasing the frequency of bowel movements. However, it can take up to four days after you start using it to have a bowel movement.
Although most people tolerate this laxative well, GlycoLax can cause side effects, such as nausea, gas, and diarrhea. Fortunately, if problems do occur, they tend to be minor and easily treated.
