Lactulose Dosing Considerations for Infants

Important Clinical Pitfalls

• Excessive lactulose can cause dehydration, hypernatremia, and severe perianal skin irritation in infants, emphasizing the need for careful dose management 1, 2
• Aspiration risk is increased if excessive diarrhea occurs due to lactulose overdose, highlighting the importance of monitoring stool output 1
• The American Academy of Pediatrics and other guideline societies imply that the misconception of requiring much larger doses for lack of effect is dangerous, and instead, other causes should be searched or alternative therapies considered 1

Dose Adjustment Strategy

• The Hepatology society recommends that if diarrhea occurs, the dose should be reduced immediately, and if diarrhea persists despite dose reduction, lactulose should be discontinued to prevent dehydration and electrolyte disturbances 1, 2
