What is Bactroban for?

Bactroban is a brand product that contains Mupirocin, which is a type of RNA synthetase inhibitor. Bactroban ointment is indicated to treat impetigo (a bacterial skin infection) due to Staphylococcus aureus and Streptococcus pyogenes infection, while Bactroban nasal ointment is used to treat nasal infections of Staphylococcus aureus (including methicillin-resistant S. aureus (MRSA)).

How to use it?

Bactroban is available as an ointment for application on skin or to the nostril. Wash your hands before and after applying this medication.

For impetigo, apply a small amount of ointment, with a cotton swab or gauze pad, to the affected areas 3 times daily for 10 days maximum. You can cover the treated area with gauze dressing if desired.

For nasal colonisation with Staphylococcus aureus, apply approximately one-half of the nasal ointment from the single-use tube into 1 nostril and the other half into the other nostril 2 times daily (morning and evening) for 5 days. 

After application, close the nostrils by pressing together and releasing the sides of the nose repetitively for approximately 1 minute. This will spread the ointment throughout the nares. Discard the tube after usage and do not re-use.
