Movicol (Macrogol 3350 (also known as polyethylene glycol 3350) with electrolytes) — Uses, Dosage, Side Effects & Safety

Drug class: Osmotic laxative

Overview

Movicol is a laxative used to treat constipation in adults and children. It is also used for more severe cases such as fecal impaction. Movicol works by holding water in the bowel, which softens the stool and makes it easier to pass. The active ingredient, macrogol 3350, is an osmotic agent that draws water into the colon, increasing stool volume and triggering natural bowel movements. Movicol also contains electrolytes (sodium, potassium, and bicarbonate) to help maintain the body's normal salt and water balance. Key points for patients: Movicol is generally well tolerated and does not cause sudden urgency. It is important to dissolve the powder in water before taking and to follow dosing instructions carefully. Movicol is not habit-forming and can be used for both short-term and longer-term management of constipation as directed by your healthcare provider.
