Mupirocin Ointment

Mupirocin ointment is an antibiotic ointment used to treat bacterial skin infections, such as impetigo (IM-pe-TYE-go). Mupirocin ointment clears skin infections by killing the bacteria that cause them, including “Staph" bacteria (Staphylococcus aureus) or “Strep” bacteria (Streptococcus pyogenes). It kills the bacteria by stopping the bacteria from being able to make protein.

Bactroban brand of mupirocin by GSK was the first brand FDA approved in 1987, then Centany brand became available in 2002, and now there are also generic brands of mupirocin available. This ointment is available on prescription, and it is not an over-the-counter medicine.

Mupirocin ointment is used for bacterial skin infections such as impetigo and wounds that have become infected and is also used to treat nasal colonization with particular antibiotic-resistant bacteria.

Mupirocin ointment (topical) is FDA-approved for the topical treatment of impetigo due to the bacteria Staphylococcus aureus and Streptococcus pyogenes.

Bactroban nasal ointment is FDA-approved for the eradication of nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) in adult and pediatric patients (aged 12 years and older) and healthcare workers as part of a comprehensive infection control program to reduce the risk of infection among patients at high risk of MRSA infection during institutional outbreaks of infections with this microorganism.

When mupirocin ointment is used for wounds that have become infected, it is an off-label use.
