What should you know about Fucidin for paronychia?

Paronychia is inflammation or infection beside the fingernail or toenail. Fucidin contains fusidic acid, an antibiotic applied to the skin. A clinician may choose it when the appearance suggests a local bacterial infection. Redness, tenderness, swelling, or discharge can also arise from irritation, repeated wet work, nail trauma, or yeast, so the medicine is not suitable for every case.

Use the prescribed amount and schedule on clean, gently dried skin, and wash your hands before and after application. Do not share the tube or put it inside the nail unless instructed. Keep the area protected from biting, picking, harsh chemicals, and prolonged moisture. If pain or swelling is increasing despite treatment, arrange a review rather than extending the course yourself. For broader infection, a clinician may discuss [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/). A fluid pocket may need [Abscess Drainage](/treatments/minor-procedures/abscess-drainage/).

Seek prompt medical assessment if redness is spreading, the finger is becoming difficult to bend, pus is trapped under pressure, or pain is severe. Fever, red streaking, marked swelling, or feeling unwell needs urgent attention. Recurrent or long-lasting nail-fold inflammation also deserves examination because dermatitis, yeast such as [Skin Yeast Infection](/conditions/cutaneous-candidiasis/), or another problem may need different care.

Ask whether the infection looks bacterial, whether an abscess is present, how long to use the ointment, and what changes should trigger a review. Mention allergies, pregnancy, diabetes, immune problems, and medicines that affect healing.
