Mupirocin

What is Mupirocin

Mupirocin is a topical antibiotic used to treat certain bacterial skin infections. It belongs to a class of medicines called antibacterial agents for topical use.

Approved and common uses

Impetigo (a contagious skin infection)

Infected minor cuts, wounds, and abrasions

Secondary bacterial skin infections

Nasal decolonisation of certain bacteria such as Staphylococcus aureus including MRSA in specific clinical settings

Available formulations and strengths

Topical ointment commonly 2%

Topical cream commonly 2%

Intranasal ointment for nasal bacterial colonisation

Mupirocin is intended for external use on the skin or inside the nose, depending on the formulation.

What is the Recommended Dosage of Mupirocin

Dosage varies based on

Type and severity of infection

Patient age

Skin area affected

Overall health status

Available dosage forms

Skin ointment

Cream

Nasal ointment

Treatment duration is usually short and guided by response to therapy. Exact dosing frequency and duration must follow instructions from a licensed medical specialist, typically a dermatologist or infectious disease specialist. Patients should not extend treatment longer than recommended.

How Mupirocin Works

Mupirocin works by blocking bacteria from producing proteins they need to grow and multiply. This stops the spread of infection and allows the body’s immune system to clear bacteria.

It treats bacterial skin infections but does not work against viral or fungal conditions. Improvement may occur within a few days, but completing the prescribed course helps prevent resistance.
