Fungal Nail Infections

After your fungal nail infection has been successfully treated, take steps to prevent the infection from coming back.

• Before bed, thoroughly wash and dry your feet or hands. Then apply a Reference topical antifungal, such as terbinafine (Lamisil) or ciclopirox (Penlac), directly to your skin or nail. Use the topical medicine twice a week for up to 1 year.^{Reference 2}
• Keep your feet and hands dry. Dry skin and nails are less likely to become infected. Apply powder to your dry feet or hands after you take a shower or bath.
• Wear socks. If they get damp, change them to keep your feet dry.
• Wear sandals or dry roomy shoes made of materials that allow moisture to escape.
• Wear shower sandals or shower shoes when using a public pool or shower. Let them dry between uses.
• Don't share shoes, socks, nail clippers, or nail files with others.
• Avoid injuring your nail. Cutting nails too short is a common cause of nail injury. If you decide to get artificial nails or have a manicure, go to a salon that uses sterile instruments. Nail manicure and certain nail products can damage the nail or cuticle, making the nail more susceptible to infection.

If you have diabetes, take special care of your feet to prevent nail infections. And if you smoke, try Reference quitting.
