Clindamycin for paronychia: what to know

Paronychia is inflammation or infection beside a fingernail or toenail. Bacteria can enter through a torn cuticle, nail biting, picking, or a small injury. Clindamycin is an antibiotic that targets certain bacteria; a clinician chooses it only when the suspected organism and your medical history make it appropriate. A recurrent problem may instead involve moisture, irritation, or yeast, such as a skin yeast infection.

Redness, tenderness, warmth, swelling, and throbbing can occur. A pocket of pus needs an examination because medicine alone may not release the pressure. The appearance of the nail fold and the speed of change help guide the decision.

Use clindamycin exactly as prescribed and complete the instructed course unless the prescriber tells you to stop. Do not share leftover antibiotics or apply a formulation intended for another body area. Keep the nail fold clean and dry, avoid cutting or pushing back the cuticle, and protect it from further picking or biting. Warm water soaks may soothe mild inflammation, but stop if the skin becomes more irritated.

If a clinician sees a collection of pus, they may recommend abscess drainage. Antibiotic therapy for a skin infection may be adjusted if the area is not improving or if another cause is found.

Arrange prompt medical assessment if redness is spreading, pain is rapidly worsening, pus is building, the fingertip is becoming very swollen, or you cannot bend the finger comfortably. Seek urgent help for fever, red streaks moving up the hand or foot, marked weakness, or feeling seriously unwell. Contact the prescriber if severe diarrhoea, blood in the stool, hives, facial swelling, or breathing trouble develops during clindamycin use.

Ask whether the infection looks bacterial, whether drainage is needed, how to protect the nail fold while it heals, and what symptoms should trigger a review. Mention previous antibiotic reactions, bowel problems after antibiotics, pregnancy, and medicines or supplements you take.
