Mupirocin Treatment Guidelines

Standard Topical Dosing for Skin Infections

The American Academy of Pediatrics and Infectious Diseases Society of America recommend a three-times-daily regimen of mupirocin 2% ointment for 5 days for impetigo 1

For eradication of nasal Staphylococcus aureus carriage, apply mupirocin 2% ointment intranasally twice daily for 5 days, as recommended by Clinical Infectious Diseases guidelines 2, 3
Approximately 15 grams of ointment is needed for the complete twice-daily, 5-day intranasal course 4

A combined approach of intranasal mupirocin twice daily for 5 days plus daily bathing with chlorhexidine or dilute bleach baths is preferred for recurrent skin and soft tissue infections, according to Clinical Infectious Diseases guidelines 2, 3
Bleach bath concentration should be 1 teaspoon per gallon of water for 15 minutes, twice weekly for 3 months 3

The Infectious Diseases Society of America recommends completing the full 5-day course of mupirocin even if symptoms improve quickly, as stated in Praxis Medical Insights guidelines 4
Patients with numerous lesions or no response to treatment within 3-5 days should switch to oral antibiotics, as advised by the American Academy of Pediatrics and Praxis Medical Insights guidelines 1
Hands should be washed thoroughly before and after each application to prevent spread of infection, according to Praxis Medical Insights guidelines 4

Patients with numerous lesions or outbreak-associated impetigo should receive oral antibiotics instead, as recommended by the American Academy of Pediatrics and Praxis Medical Insights guidelines 1
For recurrent abscesses, incision and drainage remains the primary treatment, and mupirocin decolonization is only adjunctive, according to Clinical Infectious Diseases guidelines 2
Oral antibiotics should be considered if topical therapy fails, as advised by the American Academy of Pediatrics and Praxis Medical Insights guidelines 1
