Should lactulose be stopped after having a bowel movement?

Generally, lactulose should not be stopped after bowel movement occurs.

Lactulose helps facilitate defecation and reduce blood ammonia levels, and is effective for constipation and hepatic encephalopathy. Generally, if bowel movements become regular after taking lactulose and no significant side effects occur, the dose may be gradually reduced under a doctor's guidance until discontinuation. However, if constipation recurs after stopping the medication, continued use of lactulose or alternative treatments may be necessary. Although lactulose is relatively safe, it should not be used in large doses over a long period. Prolonged high-dose use of lactulose may lead to adverse effects such as intestinal dysfunction and electrolyte imbalances. Therefore, lactulose must be taken strictly according to medical advice, following the prescribed dosage and duration. Otherwise, severe acidosis may result, especially in patients with renal failure. Additionally, patients are advised to maintain a light diet, get adequate rest, and avoid staying up late.
