What Athlete's Foot Is and How Dr Dray Diagnoses It
Athlete's foot, or tinea pedis, is a fungal skin infection of the feet caused most often by dermatophytes such as Trichophyton rubrum and Trichophyton mentagrophytes. Dr Dray, a board-certified dermatologist, notes that the condition typically appears as itching, scaling, cracking, or blistering between the toes or on the soles, and she emphasizes that visual inspection and sometimes a potassium hydroxide skin scraping confirm the diagnosis. The American Academy of Dermatology lists athlete's foot as one of the most common superficial fungal infections, affecting roughly 10 to 15 percent of the global population at any given time, with prevalence highest in warm, humid climates and among people who wear tight, non-breathable footwear for long periods.

Dr Dray explains that misdiagnosis is common because eczema, psoriasis, and contact dermatitis can mimic fungal symptoms, and she advises patients to avoid self-treating with steroid creams that can worsen a fungal infection by suppressing local immunity. She also points out that while athlete's foot is rarely a serious medical threat, untreated cases can lead to secondary bacterial infections, cellulitis, or chronic scaling that spreads to the toenails, a condition called onychomycosis. The Centers for Disease Control and Prevention notes that dermatophyte infections are not reportable in the United States, but clinic data show they account for a large share of outpatient dermatology visits, especially in the summer months when barefoot activity increases exposure risk fungal infection guidance from the CDC.
OTC and Prescription Treatments Recommended by Dr Dray
Dr Dray recommends over-the-counter topical antifungals as first-line therapy for mild to moderate athlete's foot, specifically creams or sprays containing terbinafine, clotrimazole, miconazole, or tolnaftate, applied once or twice daily for two to four weeks. She stresses that patients should continue treatment for at least one to two weeks after symptoms resolve to reduce relapse rates, and she notes that terbinafine cream tends to have shorter treatment courses than azole-based products because it is fungicidal rather than fungistatic. The Mayo Clinic states that OTC antifungals clear symptoms in most mild cases within four weeks, but if the infection involves the toenails, is widespread, or does not improve after two weeks of consistent use, a prescription oral antifungal such as oral terbinafine or itraconazole may be needed Mayo Clinic athlete's foot treatment overview.
For resistant or recurrent cases, Dr Dray may prescribe oral terbinafine 250 mg daily for two to six weeks or oral itraconazole in pulse dosing, and she orders baseline liver function tests before treatment because oral antifungals carry a small risk of hepatotoxicity. She also discusses non-pharmacological measures such as using antifungal powders in shoes, rotating footwear to allow drying, wearing moisture-wicking socks, and avoiding shared showers or towels in locker rooms and communal pools. The U.S. Food and Drug Administration has approved several topical and oral antifungal products for athlete's foot, and the FDA's database shows that terbinafine hydrochloride cream and clotrimazole remain among the most frequently recommended agents by dermatologists for uncomplicated tinea pedis
