Antibiotics for paronychia on a finger

A clinician bases treatment on whether there is a drainable pocket, cellulitis beyond the nail fold, significant tenderness, and health factors that make infection harder to control. Mild early irritation may settle with local care, while a deeper collection should not be squeezed at home.

Paronychia is inflammation of the skin where the nail meets the finger. Bacteria can enter through a torn cuticle, hangnail, bite, manicure injury or repeatedly wet skin. The fold may become red, swollen and throbbing, and a pale or yellow pocket can form beside the nail.

Problems that persist or repeatedly return may have a different pattern from a sudden bacterial infection. Ongoing exposure to water or irritants, dermatitis and yeast-related inflammation can change which treatment is appropriate.

Gently clean the area, dry it carefully, and protect it from biting, picking and harsh chemicals. Gloves can limit wet work, but damp gloves should be changed. Remove rings from the affected hand before swelling makes them difficult to take off.

Use an antibiotic only when prescribed for this episode, following its directions. If drainage is performed, keep the dressing clean and follow the wound-care instructions. Avoid cutting the cuticle or trying to puncture the swelling with a needle.

Obtain prompt care if pus is visible, pain is intensifying, redness travels beyond the nail fold, finger movement becomes difficult, or fever appears. People with diabetes, reduced immunity or poor circulation should seek assessment early rather than attempting drainage themselves.

Emergency evaluation is appropriate for rapidly spreading swelling, severe pain with a tense fingertip, red streaks moving up the hand or arm, confusion, or marked weakness.

Ask whether pus is present, whether drainage would help more than medicine alone, how to dress the finger, and which signs suggest that infection is spreading into deeper tissue.
