Clindamycin for pitted keratolysis: what to know

Pitted keratolysis is a bacterial infection affecting the outer layer of skin on pressure areas of the soles, especially when feet stay warm and damp. Small pits, softened skin, and a strong odour can appear. Body odour from the feet may be more noticeable after wearing enclosed shoes or during heavy sweating.

Clindamycin can be prescribed as a topical treatment, or another form may be considered after an assessment. The choice depends on the extent of the affected skin, previous treatment, allergies, and whether another foot problem is present. The medicine does not remove the moisture conditions that let the bacteria thrive.

Apply clindamycin only in the amount and pattern instructed. Wash and dry the feet carefully, including between the toes, change damp socks, rotate shoes, and allow footwear to dry fully before wearing it again. Avoid sharing towels, socks, or shoes while the skin is affected. A prescription antiperspirant may be discussed if sweating is a major trigger.

Topical antibiotic therapy is often paired with moisture control. Do not keep applying an antibiotic indefinitely without review, especially if the pits, odour, or tenderness persist. A clinician can check whether the diagnosis is correct and whether the skin has become irritated by treatment.

Seek medical advice if pain, warmth, swelling, cracking, or redness develops, if the affected area spreads, or if there is no clear improvement with the prescribed plan. Arrange earlier review if you have diabetes, poor circulation, reduced sensation, or a weakened immune system. Get urgent help for fever, rapidly spreading redness, severe pain, or feeling very unwell.

Ask whether the pits and odour fit pitted keratolysis, how long to use clindamycin, what foot-drying routine suits you, and whether sweating needs separate treatment. Tell the clinician about athlete’s foot symptoms, broken skin, prior antibiotic reactions, and medicines you already use.
