What should you know about Fucidin H for impetigo?

Impetigo is a contagious bacterial skin infection that can produce blisters, oozing areas, and yellow-brown crusts. Fucidin H contains fusidic acid plus a corticosteroid. The antibiotic targets susceptible bacteria, while the steroid reduces inflammation. That combination may be chosen for a particular inflammatory skin problem, but a crusted rash can also be eczema with infection, irritation, or another condition. [Atopic Dermatitis](/conditions/atopic-dermatitis/) can make the distinction less obvious.

Apply only as prescribed and only to the areas named by the clinician. Avoid eyes, mucous membranes, and covered skin unless you have been told otherwise. Wash hands, avoid scratching, keep lesions clean and covered when advised, and do not share towels, clothing, or the tube. Do not use leftover steroid combinations on a new rash. A clinician may instead recommend [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) or [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/), depending on the extent and diagnosis.

Arrange prompt care if crusting is spreading, lesions are near the eye, pain or swelling is marked, or a child seems unwell. Fever, rapidly worsening redness, pus, or red streaks needs urgent assessment. Seek review if the rash does not improve as expected or returns after treatment; continuing a steroid-containing product without advice can delay recognition of another infection.

Ask whether the rash is impetigo or infected eczema, why the steroid is included, where to apply it, and when to stop. Check how to reduce spread at home and whether close contacts need advice.
