# Drug Description Template ## Brand Name: Duphalac 667 g/L Lactulose Oral Solution ## Generic Name: Lactulose ## About the Drug:Duphalac is a gentle laxative medicine that helps relieve constipation by softening the stool and making bowel movements easier. It also helps reduce harmful substances in the body in people with liver disease, which can improve symptoms of hepatic encephalopathy such as confusion or drowsiness. Because it works by drawing water into the bowel rather than irritating it, it is often used when a mild, effective option is needed for long-term bowel regularity. ## Indications: When do you need this medication?* Constipation: Helps soften hard stools and stimulate regular bowel movements when you are having trouble passing stool.* Hepatic encephalopathy: Used in people with liver disease to lower ammonia levels in the blood and help reduce symptoms such as confusion, sleepiness, or changes in thinking.* Preventing constipation-related discomfort: May help reduce bloating, straining, and discomfort caused by infrequent bowel movements. ## Dosage and Administration: How to use the drug safely and effectively?* Usual Dosage: * For constipation in adults: The usual starting dose is often 15–45 mL per day, followed by a maintenance dose of 15–30 mL per day based on response. * For children: The dose depends on age and should be determined by a doctor.
