Topical antibiotics for pitted keratolysis

Pitted keratolysis is a superficial bacterial infection that affects the pressure-bearing soles. Tiny shallow pits may appear, and the skin can look softened or pale after sweating. A strong foot odour is common because bacteria break down sweat and keratin on the skin surface.

A topical antibiotic is usually selected for the affected area and used as directed. It does not replace moisture control: warm, enclosed footwear and prolonged dampness can support bacterial growth even after the skin looks better.

Wash the feet, dry carefully between the toes and across the soles, and change damp socks promptly. Rotate shoes so they can dry fully. Use the prescribed medicine on clean, dry skin and avoid sharing towels, socks, or footwear.

A clinician may also recommend a product that reduces sweating when moisture is a major trigger. Stop and seek advice if treatment causes marked burning, swelling, or a new rash. Do not apply antibiotics to cracked or extensively damaged skin unless instructed.

Book a review if odour and pits persist despite careful treatment, if pain develops, or if redness spreads beyond the sole. Prompt assessment is sensible for diabetes, poor circulation, reduced sensation, or an open sore because foot problems can become harder to notice and manage.

Ask how often to apply the antibiotic, how long to use it, and whether both feet need treatment. Ask whether excess sweating is contributing, how to dry or disinfect footwear safely, and what changes would suggest another foot condition.
