Minimum Age for Mupirocin 2% Ointment Use
Mupirocin 2% ointment can be safely used starting at 2 months of age for impetigo and other minor skin infections in children. 1
FDA-Approved Age Range
- The FDA drug label explicitly states that "the safety and effectiveness of mupirocin ointment have been established in the age range of 2 months to 16 years" 1
- This approval is supported by adequate and well-controlled studies in pediatric patients with impetigo 1
Clinical Guideline Recommendations
For children with minor skin infections (impetigo) and secondarily infected skin lesions (eczema, ulcers, lacerations), mupirocin 2% topical ointment is recommended without specific age restrictions beyond the FDA-approved minimum. 2
- The Infectious Diseases Society of America (IDSA) guidelines recommend mupirocin 2% ointment for children with these conditions, referencing the pediatric evidence base that includes infants as young as 2 months 2
Dosing and Application
- Apply mupirocin 2% ointment to affected areas three times daily for 5 days for impetigo treatment 3
- The medication is for external use only and should not be applied to mucosal surfaces 1
