Sorbitol is used in constipation.

Sorbitol works by drawing water into the intestine through osmosis, which makes the stool soft and easier to pass.

Dehydration

• Together with Sorbitol, fiber rich diet containing whole grain bread and cereals, bran, fruits and green leafy vegetables, is essential to maintain healthy bowel function.
• A Sorbitol should preferably be taken at bedtime because it requires 6 to 8 hours to show impact.
• Notify your doctor if you are on a low-sugar diet because the Sorbitol contains sugars.
• Take Sorbitol after 2 hours from other medicines, as it may interfere with the absorption of other medicines.
