Osmotic laxative
Last reviewed June 2026
Who is this for?
Sorbitol is a sugar alcohol that works as an osmotic laxative — it draws water into your intestines to soften stool and help you pass it more easily. It is also used as a sweetener in some medicines and products.
Draws water into the intestinal lumen through osmotic action, increasing stool bulk and promoting peristalsis to facilitate bowel evacuation.

Explore this drug
For constipation, the usual adult dose is 30 to 50 mL of a 70% sorbitol solution taken by mouth once or as directed by your doctor or pharmacist. You can mix it with water or juice to make it easier to drink. It usually works within 30 minutes to a few hours.
Since sorbitol for constipation is usually taken only when needed (not on a regular schedule), missing a dose is not usually a concern. If your doctor has you on a schedule, take it as soon as you remember, but skip it if your next dose is close.
Sorbitol can affect how some medicines are absorbed in your stomach, especially sodium polystyrene sulfonate (Kayexalate) — taking them together can cause serious gut problems. It may also increase the laxative effect if combined with other laxatives. Alcohol may worsen stomach discomfort when taken with sorbitol.
