Should lactulose be taken on an empty stomach or after meals?

Lactulose is a commonly used medication with relatively flexible timing—it can be taken either before or after meals. It contains various ingredients such as fructose and lactose, which effectively promote intestinal motility and increase osmotic pressure in the gut, thereby relieving constipation. When using lactulose, some patients may experience adverse reactions such as diarrhea or bloating. If these symptoms occur, the medication should be discontinued immediately and medical advice sought. Additionally, it is important to avoid drinking excessive amounts of water during treatment, as this may dilute the medication and reduce its effectiveness. Besides pharmacological therapy, dietary adjustments and moderate physical activity are also crucial for managing constipation. Increasing dietary fiber intake, maintaining adequate hydration, and engaging in appropriate exercise can effectively improve constipation symptoms and enhance quality of life.
