Kirkland Signature LaxaClear is an osmotic laxative containing polyethylene glycol 3350 (PEG 3350), the same active ingredient as MiraLAX. This value pack includes three 17.9 oz bottles, providing a total of 90 doses.
Each dose contains 17 grams of polyethylene glycol 3350. The unflavored, grit-free powder dissolves easily in any beverage โ water, coffee, juice, or other liquids. It is sugar-free and gluten-free with no artificial colors or flavors.
LaxaClear works by retaining water in the stool, softening it and increasing the frequency of bowel movements. It relieves occasional constipation and generally produces a bowel movement within 1 to 3 days. Available without a prescription for adults and children 17 years of age and older. Do not use for more than 7 days unless directed by a doctor.
