Polyethylene Glycol (Miralax)

Polyethylene glycol 3350 or PEG 3350 (brand name: Miralax) is a over-the-counter type of osmotic laxative commonly used to relieve constipation. Miralax works by drawing water into the intestines, softening the stool, and promoting bowel movements.

When Miralax is ingested, PEG 3350 remains in the digestive tract without being absorbed into the bloodstream. It works by creating an osmotic effect in the intestines, meaning it attracts water from the surrounding tissues and pulls it into the bowel. This results in an increase in the volume of water in the stool, making it softer and easier to pass.

The increased water content in the stool helps to stimulate bowel movements and relieve constipation. It also helps to hydrate and soften the stool, making it less likely to be dry and hard, which can cause discomfort during bowel movements.

Miralax is typically taken orally by mixing it with a liquid, such as water or juice. It usually takes about 12 to 72 hours for Miralax to produce a bowel movement. It is important to follow the instructions provided by your healthcare provider or the packaging of Miralax when using the medication.

As always, if you have persistent or severe constipation, it is recommended to consult a healthcare professional for proper evaluation and guidance. They can help determine the underlying cause of constipation and recommend the most appropriate treatment approach.
