MiraLAX Drug Class
MiraLAX® (polyethylene glycol 3350) is an over-the-counter (OTC) laxative medication used to treat occasional constipation. Like all OTC medications, it is available without a prescription.
As part of a class of drugs called osmotic laxatives, MiraLAX works by drawing water into the colon, making the stool soft, and increasing the number of bowel movements. It will usually cause a bowel movement in one to three days.
Although most people tolerate this laxative well, MiraLAX can cause side effects. Some of these possible problems include nausea, diarrhea, and gas. In most cases, reactions to this laxative are minor and easy to treat.
