How to Treat a Fungus Infection on Your Finger

Fungal infections are common on the hands and feet, particularly under and around the nails, and can cause symptoms such as red, swollen and flaky skin with intense itching. These infections, although usually not serious, often require prolonged treatment with topical and oral medications.

Things You'll Need

• Soap
• Towel
• Topical antifungal medication

Instructions

1. Clean the affected area with soap and water; pat dry gently to avoid irritating the infected finger.

2. Apply a small amount of topical, over-the-counter antifungal cream like terbinafine (Lamisil) or ketoconazole (e.g., Nizoral). This treatment should be applied twice daily.

3. If the symptoms do not resolve within a week of using over-the-counter medications, consult a doctor for prescription products. Prescriptions include stronger versions of topical creams and oral medications (e.g., Lamisil tablets) to take once daily. Oral treatment may be necessary for up to four months to resolve symptoms and completely remove the fungus from the affected area.

Tips & Warnings

• Fungal infections thrive in warm, moist environments, so be certain to dry the affected areas gently but thoroughly and avoid covering the area for prolonged time periods.
