Nasal mupirocin has an important role to play in the prevention of Staphylococcus aureus infection by eliminating nasal carriage of this organism. Indeed, in many countries nasal mupirocin is one of the mainstays for controlling outbreaks of methicillin-resistant S. aureus. Eradication of nasal S. aureus with mupirocin has been shown to be effective in preventing postoperative infections in patients undergoing cardiothoracic surgery and in preventing exit-site infections in patients undergoing haemodialysis. ⋯ Low-level resistance does not represent a significant clinical problem but high-level resistance resulting from indiscriminate use may give grounds for concern. Further review of these issues is required. As with any antibiotic, mupirocin should be used judiciously, as part of an integrated programme of infection control.
