MiraLAX offers 14 Once Daily Doses of Unflavored Powder in an 8.3 oz bottle, providing gentle constipation relief without the harsh side effects of some laxatives. As a non-stimulant osmotic laxative, MiraLAX works naturally with your body's water to hydrate, soften, and ease stool through the colon. Since its introduction as an over-the-counter laxative in 2007, MiraLAX has remained the #1 Physician Recommended OTC brand. Convenient and tasteless, it dissolves easily in any beverage without added taste or grit. Simply fill the bottle cap to the indicated line, mix into 4 to 8 ounces of hot or cold beverage, and drink for relief typically within 1-3 days.
