What Is Mupirocin Ointment?
Mupirocin ointment is a prescription-only topical antibiotic designed to treat and prevent common bacterial skin infections. This medication comes in a 2% ointment form and is marketed under several brand names, such as Bactroban and Centany[2][3].
Mupirocin is not an over-the-counter product; it requires a healthcare provider’s prescription. It is often recommended when a skin infection is caused or complicated by bacteria that are sensitive to its action[1].
How Does Mupirocin Work?
Mupirocin targets bacteria by blocking the production of essential proteins required for their survival and multiplication.
- It is especially effective against Staphylococcus aureus (including MRSA) and Streptococcus pyogenes, two of the most common culprits behind skin and soft tissue infections[2][3].
- By disrupting protein synthesis, mupirocin halts bacterial growth, allowing the body’s natural defenses to heal the affected area[4].
Primary Uses and Indications
Mupirocin ointment is clinically approved for several important uses, and also prescribed off-label for related conditions:
FDA-Approved Indications
- Impetigo: This highly contagious skin infection—most common among children—typically causes red sores or blisters. Mupirocin ointment is the first-line treatment, rapidly reducing symptoms and preventing spread[2][5].
- Infected Small Wounds, Cuts, or Abrasions: Applied to minor cuts or scrapes that develop signs of bacterial infection, mupirocin helps eliminate harmful bacteria and supports healing[2][8].
Off-Label and Additional Uses
- Nasal Eradication of MRSA: Specially formulated mupirocin nasal ointment is used in hospitals and high-risk settings to eliminate MRSA colonization inside the nostrils, reducing infection risk among patients and healthcare workers[2].
- Boils, Open Wounds, and Rashes: Healthcare providers may recommend mupirocin for other infected skin conditions that haven’t responded to alternative treatments[8].

How to Apply Mupirocin Ointment
Proper application of mupirocin ointment ensures maximum efficacy and safety.
- Preparation: Always clean the affected area gently with mild soap and water before application[8].
- Application: Use clean hands to apply a thin layer of the ointment directly to the infected area, typically three times daily or as directed by your healthcare provider.
- Nasal Use: When prescribed for nasal application (e.g., for MRSA), follow your provider’s instructions precisely—usually, a small amount is applied to the inside of each nostril.
- Duration: Continue using mupirocin for the entire prescribed period, even if symptoms improve earlier. Stopping too soon can result in incomplete bacterial eradication and possible recurrence[8].

Side Effects and Safety Considerations
Most people tolerate mupirocin well, but like all medications, it can cause side effects.
Common Side Effects
- Mild burning, stinging, or pain at the application site[6]
- Itching, rash, redness, or swelling
- Increased oozing at the infection site
Serious Side Effects and Warnings
- Severe allergic reactions: These may involve swelling, trouble breathing, or intense rash. Seek immediate medical attention if these occur[5][6].
- Antibiotic-associated diarrhea: In rare cases, mupirocin can promote the overgrowth of dangerous bacteria like Clostridioides difficile, resulting in persistent or severe diarrhea.
- Secondary Infections: Long-term or excessive use increases the risk of developing alternative (often fungal) infections or antibiotic resistance[5].
Always inform your healthcare provider about pre-existing allergies and discuss all ongoing medications to avoid interactions. For a complete rundown on mupirocin side effects visit WebMD, Cleveland Clinic, or Healthline.
Common Questions (FAQ)
Below are answers to frequent questions about mupirocin ointment:
1. Can I use mupirocin ointment for fungal or viral infections?
No, mupirocin is only effective against certain bacteria, not against fungi or viruses. It should not be used for non-bacterial infections[2].
2. Do I need a prescription for mupirocin ointment?
Yes, you must have a prescription from a healthcare provider to obtain mupirocin ointment in most countries[2].
3. How long does it take for mupirocin ointment to work?
Many people notice improvement in their skin condition within a few days. However, always complete the entire course recommended by your provider to fully resolve the infection[3].
4. Can mupirocin be used on large wounds or burns?
Mupirocin is typically intended for small, localized skin infections. Extensive wounds or burns may require alternative treatments. Consult a healthcare professional for specific guidance[8].
5. What should I do if I miss a dose?
Apply the missed dose as soon as you remember. If it’s almost time for the next application, skip the missed one—never double up[2].
6. Is it safe for children?
Yes, mupirocin ointment is frequently prescribed for children, especially for impetigo. Always follow pediatric dosing recommendations provided by your doctor[2].
7. What signs suggest I should stop using mupirocin and seek medical help?
Stop using mupirocin and seek medical attention if you experience severe allergic reactions, persistent or worsening infection, or signs of antibiotic-associated diarrhea[5][6].
