Mupirocin ointment is primarily used to treat impetigo, a common bacterial skin infection [1]. It is also effective against other superficial skin infections caused by susceptible bacteria [1].
What bacteria does mupirocin target?
Mupirocin is effective against Gram-positive bacteria, including methicillin-susceptible Staphylococcus aureus (MSSA) [2]. It also targets coagulase-negative staphylococci and Streptococcus pyogenes [3]. Importantly, it is not effective against S. aureus strains that are intrinsically resistant to it, such as those with high-level mupirocin resistance [2].
How is mupirocin ointment applied?
Mupirocin ointment is applied topically to the affected skin area [1]. For impetigo, it is typically applied three times a day for a duration of 5 to 14 days, depending on the severity of the infection and the specific prescribing instructions [1][4]. It is important to wash hands before and after application [4].
Are there different strengths or formulations of mupirocin?
Mupirocin is available in different strengths, with a common prescription strength being 2% [1]. It is formulated as an ointment for topical use [1].
What are the potential side effects of mupirocin ointment?
Common side effects of mupirocin ointment can include local skin reactions such as burning, stinging, itching, or redness at the application site [1]. Some individuals may experience dryness or cracking of the skin [1].
How does mupirocin work?
Mupirocin inhibits bacterial protein synthesis by reversibly binding to the bacterial isoleucyl-tRNA synthetase enzyme [3]. This action prevents the incorporation of isoleucine into bacterial proteins, thereby halting bacterial growth [3].
When might mupirocin resistance be a concern?
While mupirocin has historically shown low rates of resistance, resistance can emerge, particularly with widespread or prolonged use [5]. High-level mupirocin resistance in Staphylococcus aureus is a recognized issue [2].
Can mupirocin be used for other skin conditions?
Mupirocin is also used to prevent skin infections in certain situations, such as in patients undergoing hemodialysis or those with specific skin conditions that increase their risk of infection [1]. It can be used for nasal decolonization of S. aureus in some contexts [5].
Where can I find more information about mupirocin?
