Bactroban ointment is a topical antibiotic used primarily to treat certain skin infections caused by bacteria, such as impetigo (school sores), infections of hair follicles (folliculitis), and boils[1][2][3]. It is also used for other infected skin conditions, including areas damaged by eczema, dermatitis, psoriasis, herpes (cold sores), wounds, cuts, grazes, insect bites, and minor burns[1].
The active ingredient in Bactroban is mupirocin, which works by blocking bacterial protein synthesis, effectively stopping the growth and reproduction of the bacteria[2]. Bactroban is effective against common skin infection bacteria such as Staphylococcus aureus (including some strains of MRSA) and Streptococcus pyogenes[1][2][7].
It is generally applied to the affected skin area up to three times a day, often for a period of 1 to 2 weeks, depending on the doctor’s instructions and the severity of the infection[4][7].
Bactroban ointment is not effective against fungal or viral infections and should not be used inside the eyes, on large open wounds, or on severe burns unless directed by a doctor[1][4]. Intranasal formulations are available but are prescribed separately mainly for nasal decolonization of MRSA[2].
