MiraLAX® is a nonstimulant laxative that works with the water in your body to give you gentle, effective relief from occasional constipation — with no harsh side effects.
Not All Laxatives Are the Same
Osmotic Laxatives
Osmotic laxatives like MiraLAX® attract water and keep it in your colon, allowing them to hydrate and soften stools, unblocking your system without causing harsh side effects.
Stimulant Laxatives
In contrast, stimulant laxatives make your body go by forcefully stimulating the nerves in your colon. They may also cause harsh side effects like cramping or sudden urgency.
MiraLAX® is the #1 Doctor-Recommended Choice
