Begin with a low dose of lactulose, typically 15-30 mL daily. This starting point allows your body to adjust gradually. Observe your bowel movements closely; regular, soft stools are your goal.
Increase your dosage gradually, if needed. Add 15 mL every 1-3 days until you achieve comfortable, regular bowel movements. Remember to listen to your body and avoid drastic increases. A maximum daily dose is usually 60 mL, but consult your doctor before exceeding 45 mL.
The optimal dosage varies significantly among individuals depending on factors like age, overall health, and the severity of constipation. Children require lower doses adjusted to their weight and age. Always consult a healthcare professional for personalized advice, especially for children or individuals with pre-existing medical conditions.
Important Note: Lactulose works by drawing water into the intestines, so increasing fluid intake alongside lactulose is key for its effectiveness and helps prevent dehydration. Pay attention to any side effects like bloating or gas. If these are severe, contact your doctor to discuss your dosage or consider alternative treatments.
