Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Duphalac Lemon Oral Solution contains Lactulose (3.335gm/5ml). It belongs to the Osmotic laxative (disaccharide) class of medicines.
Constipation; hepatic encephalopathy (to reduce blood ammonia levels)
Lactulose is an osmotic laxative that draws water into the colon, softening stool and promoting bowel movements. In hepatic encephalopathy, it acidifies colonic contents and traps ammonia as ammonium, reducing absorption.
Take by mouth as directed, with or without food; measure dose using a cup/spoon. For constipation, effect may take 24-48 hours; drink adequate fluids. For hepatic encephalopathy, dose is adjusted to achieve 2-3 soft stools/day.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
An overdose of this medicine can cause severe loose motions, dehydration and salt imbalance. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Duphalac Lemon Oral are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.
