What antifungal medication is best for treating athlete’s foot?

Tinea pedis, commonly known as “athlete’s foot,” is a fungal infection. Skin lesions typically begin unilaterally (on one foot) and may spread to the contralateral foot after several weeks or months. Vesicles primarily appear on the plantar surface of the toes and along the interdigital folds—most frequently between the third and fourth toes—but may also occur on the sole. These are deep-seated, small vesicles that may gradually coalesce into larger blisters. A characteristic feature of tinea pedis skin lesions is their well-demarcated borders, with progressive peripheral expansion. Due to disease progression or scratching, erosions and exudation may develop, and secondary bacterial infection may ensue, leading to formation of pustules.

Which Antifungal Medications Are Effective for Treating Athlete’s Foot?

1. Intertriginous (Macerated/Erosive) Type

When exudation is present, wet compresses with 3% boric acid solution or potassium permanganate solution may be applied until the area dries; thereafter, topical ointments or creams can be used.

2. Vesicular Type

Topical keratolytic agents such as tinctures or ointments are recommended—for example, 10–30% acetic acid solution applied topically.

3. Squamous/Hyperkeratotic Type

Topical ointments or creams may be applied directly—for example, bifonazole cream, ketoconazole cream, or terbinafine ointment.

4. Refractory Infections

Oral antifungal therapy may be considered, using agents such as itraconazole or terbinafine.

Additional Information: How to Prevent Athlete’s Foot

1. Avoid Exposure

Interrupt transmission routes by avoiding contact with infected sources. For indirect transmission, avoid wearing communal slippers and sharing towels. When visiting public areas such as gyms, swimming pools, or communal showers, bring your own slippers or footwear.

2. Maintain Hygiene

Wear well-ventilated shoes to keep feet dry and clean. Wash feet several times daily, change socks frequently, and cultivate good personal hygiene habits.
