Patient leaflet - Bactroban 2% ointment

1 What Bactroban is and what it is used for

Bactroban 2% Ointment (called ‘Bactroban’ in this leaflet) contains the active substance called mupirocin. Bactroban is an antibiotic ointment.

It is used:

  • to treat skin infections on the skin such as

    • infected hair follicles which form pimples containing pus (“folliculitis”),
    • an infectious skin infection with blistering and crusting known as “impetigo” or
    • recurring boils (“furunculosis”)
  • to kill various bacteria which cause other skin infections including Staphylococci, Streptococci and E. coli. This group includes MRSA (Methicillin Resistant Staphylococcus aureus).
  • This ointment is for external use on your skin only.

2 What you need to know before you use Bactroban

Do not use Bactroban:

  • if you are allergic (hypersensitive) to mupirocin or any of the other ingredients of this medicine (listed in section 6).

Do not use if the above applies to you. If you are not sure do not use this medicine. Talk to your doctor, nurse or pharmacist before using Bactroban.

Warnings and precautions

  • Bactroban can cause severe skin reactions or allergies. See ‘Conditions to look out for’ in Section 4
  • Bactroban is not suitable for use in your eyes, nose or around intravenous cannula (‘drip’) sites. Thrush (a yeast yeast infection ) may develop if Bactroban is used for a long time. If this occurs, tell your doctor, pharmacist or nurse.

Keep the ointment away from your eyes.

  • If the ointment gets into your eyes accidentally, wash them thoroughly with water. Other medicines and Bactroban

Tell your doctor, nurse or pharmacist if you are using, have recently used or might use any other medicines. Pregnancy and breast-feeding

3 How to use Bactroban

Always use this medicine exactly as your doctor or pharmacist has told you. You should check with your doctor or pharmacist if you are not sure.

Using this medicine

Do not mix Bactroban with any other external cream or ointment medicines on the infected area of your skin as this may reduce the effectiveness of Bactroban.

You usually apply Bactroban on your skin two to three times a day.

  1. 1. Wash and dry your hands.
  2. 2. Apply ointment to the infected area of your skin.
  3. 3. You can cover the treated area with a plaster(s) or suitable dressing(s), unless your doctor has told you to leave it uncovered.
  4. 4. Replace the cap on the tube and wash your hands.

How long should you use Bactroban for?

Use Bactroban for as long as your doctor has told you. If you are not sure, ask your doctor, nurse or pharmacist. The bacteria are normally cleared from your skin within 10 days of starting treatment. Do not use for more than 10 days. Throw away any ointment that is left over. A20021986-00
