Can I Put Mupirocin Ointment Inside My Nose or On a Pimple?

Mupirocin ointment is a topical antibiotic often prescribed for certain bacterial skin infections. It works by stopping the growth of bacteria on the skin. You may have heard of it for treating impetigo or other minor cuts and scrapes infected with Staphylococcus aureus. But what about using it inside your nose or on a pimple? Below, we’ll explain the approved mupirocin ointment uses, when off-label applications come up, and what you need to know before trying it on yourself.

What Is Mupirocin Ointment?

Mupirocin is an antibiotic derived from Pseudomonas fluorescens. The 2% ointment form is FDA-approved for:

• Impetigo: A contagious skin infection causing red sores that can ooze and form a yellowish crust.
• Secondarily infected small cuts, wounds or abrasions: When bacteria have invaded minor skin injuries.

Because mupirocin specifically targets gram-positive bacteria like Staph. aureus, it’s not helpful against fungal or viral skin problems.

Mupirocin Ointment Uses

Use this section to optimize for “mupirocin ointment uses”:

1. Topical skin infections
   • Impetigo (children and adults)
   • Infected eczema
   • Minor abrasions, lacerations, or surgical wounds with bacterial contamination

2. Nasal staph decolonization (off-label or specialized formulation)
   • Preventing Staph aureus spread in medical settings
   • Reducing MRSA (methicillin-resistant Staph aureus) carriage before surgery

3. Off-label dermatology applications
   • Limited use on acne lesions when Staph aureus is confirmed or suspected
   • Small-scale application to cuts or bites at risk of staph infection

Can You Put Mupirocin Inside Your Nose?

Nasal Decolonization

Mupirocin nasal ointment (often Bactroban™ Nasal) is specially made for inside-nose use. It’s FDA-approved to eradicate Staph aureus from the nostrils, helping prevent infections in high-risk patients (e.g., before surgery).

Standard instructions for nasal mupirocin:

• Apply a pea-sized amount to the inside of each nostril
• Gently press the sides of your nose together and massage for 1 minute
• Repeat twice daily for 5 days

Using Regular Mupirocin Ointment Intranasally

Some providers may prescribe the skin ointment inside the nose if the dedicated nasal tube is unavailable. Although the active drug is identical, the skin ointment is greasier and thicker. If you’re considering this:

• Check with your doctor first—never use prescription medication off-label without guidance.
• Do not exceed the recommended duration (usually 5–10 days total).
• Monitor for irritation: burning, itching or increased redness

Can You Put Mupirocin on a Pimple?

Why It’s Not First-Line for Acne

Acne pimples (comedones, papules, pustules) mainly involve clogged pores, excess oil, and Propionibacterium acnes (Cutibacterium acnes), not Staph aureus. Standard acne treatments include:

• Benzoyl peroxide
• Salicylic acid
• Topical retinoids (adapalene, tretinoin)
• Oral or topical antibiotics (e.g., doxycycline, clindamycin)

Mupirocin may help if a pimple has become secondarily infected with staph, but:

• It won’t clear non-infected acne
• Overuse encourages resistant bacteria
• It may cause local irritation or contact dermatitis

When Providers May Consider It

A dermatologist might use mupirocin on a tender pustule that:

• Shows signs of staph infection (spreading redness, thick yellow crust)
• Has been swabbed and cultured positive for Staph aureus

Even then, mupirocin is typically applied for short courses (5–7 days). After improvement, you’d switch back to standard acne therapies.

Potential Side Effects

Most people tolerate mupirocin ointment well, but watch for:

• Local burning, stinging or pain
• Dryness, cracking or itching of skin
• Redness or swelling at application site
• Allergic contact dermatitis (rash, blisters)
• Very rarely, systemic effects like headache or gastrointestinal upset

If you notice severe rash, difficulty breathing, or signs of an allergic reaction, stop use and seek medical attention right away.

Precautions and Tips

• Follow the prescription. Don’t use more often or longer than directed.
• Wash hands before and after applying.
• Avoid spreading. Do not touch treated area and then other skin or surfaces.
• Do not cover with airtight dressings unless instructed.
• Tell your provider if you’re pregnant, breastfeeding, or on other medications.
• Avoid eye contact. If it gets into your eyes, rinse well with water.

When to Seek Professional Help

If your skin infection:

• Spreads rapidly or covers a large area
• Causes fever, chills or overwhelming fatigue
• Doesn’t improve within 3–5 days of treatment
• Shows signs of deeper infection (intense swelling, red streaks)

…you should speak to a healthcare provider promptly. For non-urgent guidance, you might consider doing a free, online symptom check, using the doctor approved Ubie Symptom Checker before or after your appointment to help clarify your symptoms.

Key Takeaways

• Mupirocin ointment uses are primarily for bacterial skin infections like impetigo.
• A specialized nasal mupirocin product exists for eradicating Staph aureus from the nostrils; skin ointment intranasally should only be used under medical advice.
• Using mupirocin on an ordinary pimple is not recommended unless there’s a confirmed staph infection.
• Always follow your doctor’s instructions, watch for side effects, and avoid prolonged, widespread use to reduce resistance risk.

If you have any doubt about using mupirocin inside your nose or on a pimple—or if your condition worsens—be sure to speak to a doctor, especially if you experience signs that could be life-threatening or serious.
