13.10.1.1 Antibacterial preparations only used topically
Mupirocin
- Cream 2% (£5.26 = 15g)
- Ointment 2% (£15.00 = 15g)
Indications
- Bacterial skin infections
Dose
- Apply up to three times a day for up to 10 days
Notes
- Mupirocin ointment and cream are not interchangeable - specify formulation required.
- Mupirocin should only be used on recommendation of Infection Control or Microbiology. Should be kept in reserve to avoid resistance developing and is particularly useful in treating MRSA.
The use of topical antimicrobial agents has long been discouraged, on the grounds that it carries a particular risk of selecting resistance. However, some topical antibacterial use is strongly defensible, for example:
- Use of sulphonamides with silver nitrate to prevent and treat burn wound infections
- Use of mupirocin to eliminate colonisation and superficial infections caused by MRSA. Nevertheless, mupirocin can be misused e.g. by being given as blanket treatment or prophylaxis.
