Duphalac Syrup is a 300ml oral solution used as a laxative medication. It contains lactulose as the active ingredient and helps treat constipation by drawing water into the bowel to soften stools and promote regular bowel movements. The syrup comes in a white plastic bottle with a measuring cap for accurate dosing. As with any medication, this should be taken as prescribed by a healthcare professional. Store in a cool, dry place away from direct sunlight.
