What Mupirocin is used for
Mupirocin is an anti-infective medicine, specifically an antibiotic, used to treat certain bacterial infections affecting the eyelids and surrounding skin. It is prescribed by ophthalmologists for conditions such as:
- Staphylococcal blepharitis: This is an inflammation of the eyelids, often caused by Staphylococcus bacteria, leading to redness, itching, and crusting along the lash line.
- Lid/skin infection: Various bacterial infections affecting the skin of the eyelids.
- MRSA decolonisation of the lid margin: MRSA (Methicillin-resistant Staphylococcus aureus) is a type of bacteria that can be resistant to some common antibiotics. Mupirocin can be used to reduce the presence of MRSA on the eyelid margins, helping to prevent more serious infections.
It is important to remember that Mupirocin is a prescription medicine and should only be used as directed by your eye doctor after a proper diagnosis.
How it works
Mupirocin works by targeting and stopping the growth of certain bacteria that cause infections. Specifically, it acts by blocking bacterial protein synthesis. This means it interferes with the bacteria’s ability to create essential proteins, particularly by inhibiting an enzyme called isoleucyl-tRNA synthetase. Without these proteins, the bacteria cannot grow or multiply, which helps your body clear the infection. This mechanism makes it effective against a range of bacteria, including those commonly found in eyelid infections.
How it’s used
Mupirocin is a skin ointment designed for application to the eyelids. It is crucial to use this medicine exactly as prescribed by your ophthalmologist.
Typical Dosing: You will usually be advised to apply a small amount of the ointment to the lid margin (the edge of your eyelid where the eyelashes grow) 2 to 3 times a day. Your doctor will specify the exact frequency and duration of treatment based on your condition.
How to Apply Eyelid Ointment Correctly:
- Wash Your Hands: Always wash your hands thoroughly with soap and water before touching your eyes or the ointment tube.
- Clean the Area (if advised): Your doctor might ask you to gently clean your eyelids before application, especially if there is crusting or discharge.
- Open the Tube: Carefully remove the cap from the ointment tube. Avoid touching the tip of the tube with your fingers or any other surface to prevent contamination.
- Apply the Ointment: Gently pull down your lower eyelid to create a small pocket. Squeeze a small amount (a thin line, usually about a quarter of an inch) of ointment along the inside of your lower eyelid margin. For upper lid application, you may need to look down and pull the upper lid gently away from the eye. Alternatively, your doctor might instruct you to apply it directly to the base of the eyelashes.
- Close Your Eye: Gently close your eye for a minute or two to allow the ointment to spread. You might experience temporary blurred vision, which is normal.
- Wipe Excess: If there is any excess ointment on your skin, you can gently wipe it away with a clean tissue.
- Replace the Cap: Immediately replace the cap on the ointment tube to keep it sterile.
- Wash Hands Again: Wash your hands again after applying the medicine.
Remember, consistency is key. Continue using the ointment for the full duration prescribed by your doctor, even if your symptoms improve sooner. Stopping early can lead to the infection returning.
Always follow your ophthalmologist’s exact instructions.

Precautions & side effects
When using Mupirocin ointment, it’s important to be aware of certain precautions to ensure safe and effective treatment:
- For Eyelid Skin Use Only: This ointment is specifically formulated for application to the skin of the eyelids and the lid margin. It is NOT for instilling directly into the eye itself. Applying it inside the eye can cause irritation or other issues.
- Prescription Medicine: Mupirocin is a prescription-only medicine. Use it only under the guidance and direction of a qualified ophthalmologist. Do not self-medicate or use an old prescription without consulting your doctor.
- Avoid Contamination: To prevent contamination of the ointment and potential eye infection, do not touch the tip of the ointment tube to your eye, eyelid, fingers, or any other surface.
- Temporary Blurred Vision: After applying the ointment, you might experience temporary blurred vision. This is normal due to the ointment’s consistency. Avoid driving or operating machinery until your vision clears.
- Allergic Reactions: If you experience any signs of an allergic reaction (like severe itching, redness, swelling, or rash around the application area), stop using the ointment and contact your doctor immediately.
- Complete the Course: Always complete the full course of treatment as prescribed by your doctor, even if your symptoms improve. Stopping early can lead to the infection recurring or becoming more difficult to treat.
- Inform Your Doctor: Always inform your ophthalmologist about any other medications you are taking, including over-the-counter drugs, supplements, and herbal remedies, to avoid potential interactions.
- Storage: Store the ointment as directed, usually at room temperature, away from direct sunlight and moisture, and out of reach of children.
If your condition does not improve or worsens after using Mupirocin as directed, contact your ophthalmologist promptly.
Understanding Eyelid Infections and Blepharitis
Our eyelids play a crucial role in protecting our eyes, but they can sometimes become inflamed or infected. One common condition treated with Mupirocin is blepharitis, particularly staphylococcal blepharitis. Blepharitis is an inflammation of the eyelids, often affecting the lash line. It can make your eyelids red, itchy, swollen, and crusty, especially in the mornings. While it’s usually not serious, it can be uncomfortable and persistent. Staphylococcal blepharitis is caused by an overgrowth of Staphylococcus bacteria, which are normally present on our skin but can sometimes multiply and cause problems. Other lid/skin infections can also occur on the delicate skin around the eyes due to various bacteria. MRSA (Methicillin-resistant Staphylococcus aureus) is a specific type of bacteria that can be more challenging to treat due to its resistance to some antibiotics. When MRSA is present on the eyelid margins, it’s called decolonisation, and Mupirocin can be used to reduce its presence and prevent more serious infections. Understanding these conditions helps in appreciating why your doctor has prescribed a specific antibiotic like Mupirocin.
Correct Application and Hygiene for Eye Ointments
Proper application of eye ointment is vital for its effectiveness and to prevent further infection. Always begin by washing your hands thoroughly with soap and water. This is the most crucial step to avoid introducing new germs to your eye area. If your doctor has advised you to clean your eyelids, do so gently before applying the ointment. When applying, be careful not to touch the tip of the ointment tube to your eye, eyelid, or any other surface. This prevents contamination of the medicine. After applying a small, thin line of ointment along the lid margin, gently close your eye for a moment to allow it to spread. You might notice temporary blurring of vision, which is normal and should clear shortly. Always replace the cap immediately after use to keep the ointment sterile. Finally, wash your hands again. Maintaining good eyelid hygiene is also important alongside medication. This includes regular, gentle cleaning of the eyelids if recommended by your doctor, and avoiding rubbing your eyes excessively, especially with unwashed hands. If you wear contact lenses, your doctor will advise you on when it is safe to wear them during treatment, and it’s often recommended to avoid them until the infection clears.
General Advice: Storage, When to Seek Help, and Importance of Professional Guidance
Proper storage of your eye medicine is essential to maintain its effectiveness. Always store Mupirocin ointment as directed on the packaging or by your pharmacist, usually at room temperature, away from direct heat, sunlight, and moisture. Keep it out of reach of children. Never use eye medicines past their expiry date. It is also important to discard any remaining ointment after completing your prescribed course, as reusing old prescriptions can be dangerous and ineffective. While Mupirocin is generally safe when used as directed, it’s important to be vigilant for any signs that your condition is not improving or is worsening. If your symptoms persist, get worse, or if you develop new symptoms such as increased pain, severe redness, significant swelling, discharge, or changes in vision, contact your ophthalmologist immediately. Remember, Mupirocin is a prescription eye medicine. This means it should only be used under the supervision of a qualified ophthalmologist who can accurately diagnose your condition and determine the appropriate treatment. This page provides general education and is not a substitute for professional medical advice, diagnosis, or a prescription.
