Mupirocin for Skin Infections: How It Works & How to Use
What is Mupirocin?
Mupirocin is a prescription topical antibiotic ointment/cream used to treat bacterial skin infections. It is derived from a natural source (a bacterium called Pseudomonas fluorescens) and is formulated as a 2% concentration for external use.
Mupirocin belongs to the antibacterial agents group specifically effective against Gram-positive bacteria commonly found on the skin. It is not related to oral antibiotics like penicillin; it’s only used on the skin (or sometimes inside the nose under medical guidance) for localized infections.
This medication stops the growth of bacteria on the skin, helping to clear infection and allow healing. It’s especially effective against Staphylococcus aureus and Streptococcus pyogenes, the usual culprits in many skin infections. Because of its targeted action, it won’t treat fungal or viral infections (like ringworm or cold sores) – it works only on susceptible bacteria.
In India and worldwide, Mupirocin is available as an ointment (greasy base, good for dry lesions) and as a cream (less greasy). Both forms contain the same active ingredient. Various brands exist, but all contain mupirocin 2% as the active component.
