• Avoid contact with eyes.

• Discontinue use if sensitization or severe local irritation occurs.

• If desired, cover affected area with gauze dressing after applying cream or ointment.

• Don't use intranasal form with any other nasal spray.

• Don't use Bactroban ointment on mucosal surfaces. Use Bactroban Nasal (mupirocin calcium ointment) intranasally.

• Know that although mupirocin isn't absorbed systemically, polyethylene glycol (its water-miscible ointment base) may be absorbed from open wounds and damaged skin and may be excreted by the kidneys.

Adverse reactions

CNS: headache (with intranasal use)

EENT: rhinitis, nasal stinging or burning, pharyngitis (all with intranasal use)

GI: mouth and lip sores

Skin: pruritus (with intranasal use); dry skin, rash, redness, stinging or pain, secondary wound infection

Patient monitoring

Patient teaching

• Instruct patient to wash affected area with soap and water and dry it thoroughly, then apply small amount of drug to area and rub in gently. If desired, tell him to apply gauze dressing.

• Advise patient to complete entire course of therapy, even if symptoms disappear. Tell him to try not to miss doses.

• If patient misses a dose, tell him to apply dose as soon as he remembers. However, if it's almost time for next dose, advise him to skip missed dose and resume regular dosing schedule.

• Advise patient to contact prescriber if skin infection doesn't improve within 3 to 5 days or if it worsens.

• Caution patient not to apply drug to eye or mucous membranes (except nasal form for intranasal use).

• As appropriate, review all other significant adverse reactions.
