If you’re unsure how long to use it, whether it can be used inside the nose, or if it can be purchased over the counter, keep reading - the real answers might surprise you.


What Bactroban 15g Ointment Is Actually Used For


People who search for what Bactroban 15g ointment is used for often want a simple, trustworthy explanation.

Bactroban (mupirocin) is an antibiotic ointment designed to stop bacteria from growing on the skin.

It’s most commonly used for:

  • Impetigo

  • Infected eczema patches

  • Minor skin infections

  • Infected cuts, scrapes, and abrasions

  • Folliculitis

  • Localized staph infections

  • Post-procedure bacterial prevention (when prescribed)

It targets bacteria directly on the skin, making it one of the most trusted topical antibiotics for small, surface-level infections.


What Is Bactroban Ointment?


Bactroban ointment contains mupirocin, a prescription antibiotic.

It works by stopping bacteria from producing essential proteins, leading to the infection clearing up quickly.

Doctors often prescribe it when:

  • A small infection doesn’t need oral antibiotics

  • Skin is irritated, but bacteria are involved

  • Patients need a safe topical option with minimal systemic absorption

Its targeted approach is the reason it’s widely recommended.


How Long to Use Bactroban Nasal Ointment


If your doctor prescribes the nasal version, the timing matters.

Most clinicians recommend:

  • Use twice per day

  • For 5 days total

  • Do not extend the duration unless instructed

Using it longer than necessary doesn’t improve results and may increase the risk of resistance.


Can Bactroban Ointment Be Used in the Nose?


This is a very common question, and the answer is important. Yes, but only the nasal formula is intended for use inside the nose.

There are two versions:

  1. Bactroban Ointment (skin use)

  2. Bactroban Nasal Ointment (inside the nostrils)

The regular skin ointment should not be placed inside the nose unless specifically instructed to do so by a healthcare professional.

The nasal version is often used for staph decolonization, including the prevention of MRSA in medical settings.

Can I Buy Bactroban Ointment Over-the-Counter?

Short answer: No. But using the Alipharmahealth website you can buy from anywhere.

Bactroban requires a prescription.

If you’re looking for OTC alternatives, pharmacies sometimes recommend:

  • Bacitracin

  • Neomycin-containing ointments

  • Triple antibiotic ointments

These can help with minor irritations, but they are not identical to Bactroban, and they don’t treat certain bacteria as effectively.

If your symptoms worsen or don’t improve within a few days, you should consult a clinician.


How to Apply Bactroban 15g Ointment the Right Way


To get the best results:

1. Clean the area gently

Use mild soap and water to remove debris.

2. Apply a thin layer

A small amount goes a long way.

3. Do not rub aggressively

Light application is enough.

4. Cover with a light dressing (optional)

Some infections heal faster when protected.

5. Use it for the exact duration prescribed

Stopping early can slow healing.


When You Should Not Use Bactroban

Avoid applying it if:

  • The skin is severely burned

  • You suspect a fungal infection

  • You’re allergic to mupirocin

  • You have large or deep wounds needing medical attention

When in doubt, speak with a healthcare provider.
