Lactulose generally takes about 1 to 2 days (24 to 48 hours) to start working by softening the stool and making it easier to pass. It may take a couple of days for noticeable relief from constipation, and if symptoms persist beyond 3 days, consulting a doctor is recommended. Lactulose is an osmotic laxative that works by drawing water into the bowel to soften the stool. The onset of effect can vary slightly depending on individual response and the condition being treated, such as constipation or liver-related issues.
How Lactulose Works
Lactulose is broken down in the bowel into substances that pull water from the body into the bowel, softening the stool and easing bowel movements. It also helps remove toxins in cases of liver disease-related brain symptoms (hepatic encephalopathy).
Typical Timeframe
- Starts working generally within 8-12 hours but full effect may take up to 2 days.
- For constipation, noticeable stool softening and relief usually take 1 to 2 days.
- If no improvement after 3 days, medical advice should be sought.
Additional Notes
- Lactulose is usually taken twice a day.
- Side effects can include bloating, wind, and diarrhea, typically mild and transient.
- Not recommended for long-term use without medical supervision.
