What should you know about impetigo bullosa treatment?

Bullous impetigo produces soft, fluid-filled blisters that may appear on the trunk, limbs or in skin folds. They can rupture easily, leaving a moist red surface and a thin rim of peeling skin. Unlike some other forms of impetigo, a thick crust may not be the first sign. The condition is contagious, and bacteria can transfer through fluid, hands, clothing or towels.

A clinician may distinguish bullous impetigo from eczema, contact irritation or other blistering disorders by examining the blisters and surrounding skin. Do not puncture or peel them yourself.

Keep the area clean and lightly covered with a non-stick dressing if it is leaking or exposed to friction. Wash hands before and after changing the dressing, and use separate towels and clothing. Treatment may involve antibiotics for skin infection taken by mouth, particularly when blisters are numerous or widespread; a topical antibiotic therapy may be suitable in selected limited cases. Follow the prescribed schedule and avoid applying unapproved creams to open skin.

Arrange prompt medical assessment for new blisters that are spreading, recurring or accompanied by soreness. Seek urgent care if there is fever, marked weakness, rapidly increasing redness, severe pain, extensive peeling, or involvement of the eyes, mouth or genital skin. Infants, older adults and people with reduced immunity should be assessed early. Keep potentially contaminated items separate until a clinician advises otherwise.

Do these blisters fit bullous impetigo? Do I need an oral antibiotic or a topical treatment? How can I dress an opened blister without tearing skin? Which symptoms would mean I should return urgently?
