When is topical antibiotic therapy recommended for pitted keratolysis?

Pitted keratolysis affects the outer skin of the soles and can cause tiny depressions, softened white skin, and a strong odour. Warmth, sweat, and shoes that hold moisture create conditions in which bacteria can thrive. The appearance can overlap with other foot problems, so a clinician may inspect the soles and the spaces between the toes before treatment.

A topical antibiotic acts at the skin surface. It works best as part of a plan that also reduces moisture and friction. If the skin is deeply painful, inflamed, or not improving, the diagnosis may need to be revisited.

Apply the prescribed product to clean, thoroughly dried skin and follow the stated schedule. Change damp socks, choose breathable footwear, rotate shoes so they can dry, and wash and dry the feet carefully after sweating. Avoid sharing towels or footwear, and do not scrub the pits aggressively.

Continue the moisture-control measures after the skin improves because sweating and occlusive shoes can allow the problem to return. Ask a clinician about suitable foot antiperspirant use if sweating is a major trigger.

Arrange prompt assessment for increasing pain, spreading redness, warmth, swelling, pus, or difficulty walking. Fever, red streaking, or rapidly worsening tissue needs urgent attention, especially for someone with diabetes, poor circulation, or reduced sensation in the feet.

Ask how long to use the treatment, which drying measures are suitable, whether excess sweating needs separate care, and what signs would suggest athlete's foot, eczema, or a deeper infection instead.
