Mupirocin is an antibiotic ointment. It fights bacteria by preventing them from making proteins necessary for their survival. Specifically, it targets bacterial protein synthesis, effectively stopping bacterial growth. In your nose, this means it combats Staphylococcus aureus, a common cause of nasal infections like impetigo and folliculitis. Apply a thin layer directly to the affected area in your nose as directed by your doctor or pharmacist. Always follow the prescribed dosage and duration of treatment.
How Long Does It Take to Work?
You should see improvement within a few days, but complete bacterial eradication may take up to a week. Consistent application is key. If symptoms worsen or don’t improve after a week, consult your doctor. Do not abruptly stop using the ointment, even if you feel better.
Potential Side Effects
While generally safe, mupirocin can occasionally cause mild burning or stinging upon application. Rarely, allergic reactions such as skin rash may occur. Stop using the ointment and seek medical attention if you experience any severe reactions.
