Fucidin H Cream combines fusidic acid, an antibiotic, with hydrocortisone, a mild corticosteroid, to treat infected eczema by controlling bacterial infection and reducing inflammation. Apply a thin layer exactly as prescribed and complete the full course. Common side effects include mild burning, itching and skin irritation. Avoid prolonged use and seek medical advice if your eczema worsens, spreads or shows no improvement after treatment.
