MiraLAX is the name brand for polyethylene glycol, an over-the-counter osmotic laxative that helps relieve constipation in some people. It draws in water to make your stool softer and easier to pass.
For some people with IC, MiraLAX may be a better option than stimulant laxatives. While MiraLAX may help your constipation symptoms, it won’t address the cause. Talk with a healthcare professional about ways to relieve constipation and whether MiraLAX could be a good option if you experience occasional constipation.
