WHY is this medicine prescribed?

Mupirocin, an antibiotic, is used to treat impetigo as well as other skin infections caused by bacteria. It is not effective against fungal or viral infections.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Mupirocin comes in an ointment that is applied to the skin. Mupirocin usually is applied three times a day for 1 to 2 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use mupirocin exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Wash the affected skin area thoroughly, and then gently apply a small amount (a thin film) of the ointment. You may cover the area with a sterile gauze dressing.

Do not apply mupirocin to your eyes.

Do not apply mupirocin to burns unless told to do so by your doctor.

What SPECIAL PRECAUTIONS should I follow?

Before using mupirocin,

  • tell your doctor and pharmacist if you are allergic to mupirocin or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially chloramphenicol (Chloromycetin).
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using mupirocin, call your doctor.

What should I do IF I FORGET to take a dose?

Apply the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not apply a double dose to make up for a missed one.

What OTHER INFORMATION should I know?
