Oral antibiotics for pitted keratolysis

Pitted keratolysis affects the thick skin of the soles and can create tiny shallow pits, softened patches, and a strong odour. Sweat, heat, damp footwear, and prolonged occlusion can allow the responsible bacteria to thrive. Oral antibiotics may be considered when a clinician judges that local care is insufficient, the area is extensive, or the diagnosis needs closer assessment.

Tablets are not a substitute for reducing moisture, and they are not appropriate for every foot odour problem. A clinician may also consider topical antibiotic therapy, especially when the infection is limited to the surface.

Wash and dry the feet carefully, especially between the toes. Change damp socks, rotate breathable shoes, and let footwear dry fully before wearing it again. Use any prescribed topical or oral medicine exactly as directed, and do not use leftover antibiotics. A prescription antiperspirant may be discussed when sweating is a major contributor.

Avoid covering the soles with occlusive material for long periods. Do not scrub aggressively or dig at the pits, since broken skin can become more irritated. Improvement should be checked if odour or pits continue despite consistent moisture control.

Seek medical review for increasing pain, spreading redness, warmth, swelling, drainage, fever, or difficulty walking. Contact the prescriber for a widespread rash, breathing trouble, or severe diarrhoea after an antibiotic. Prompt assessment is also sensible when diabetes, reduced circulation, or reduced immunity makes foot problems harder to heal.

Do the pits and odour fit pitted keratolysis? Is a topical antibiotic enough? How should I control sweating and damp footwear? What changes mean the infection needs another examination?
