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 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.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.
