Nail fungus Nail fungus (onychomycosis) is very common on the feet and less common on the hands. It usually starts at the tip of the nail, with thickening or a buildup of hard keratin under the nail. The change then spreads toward the base of the nail, and in severe cases the nail may become deformed or even destroyed. White or yellow spots on the nails can also be a sign of nail fungus. What you should know Nail fungus is harmless but takes a long time and is difficult to treat. Because treatment is lengthy (6 months for the hands, 9 months for the feet), it is better to confirm the diagnosis with a laboratory sample prescribed by your doctor, to identify the fungus responsible (usually a dermatophyte, Trichophyton rubrum on the feet, and Candida albicans on the hands) and to make sure it is indeed a fungus and not, for example, psoriasis. What to avoid Do not self-medicate if you have never had nail fungus; see your doctor. Do not self-medicate if nail fungus affects the hands and you have diabetes or an immune disorder; see your doctor. Good practice People prone to onychomycosis, such as older adults and people with diabetes, are advised to check their nails regularly and see a doctor if anything looks abnormal. Treatment is more effective if it is started early. Pedicure or podiatry care is useful not to treat the fungus itself, but to remove and file down abnormal thickening. Medicines Antifungal nail lacquers or film-forming solutions have limited or very limited effectiveness. These products are based on amorolfine, ciclopirox, ciclopirox olamine, or imidazoles (econazole, fenticonazole, isoconazole), among others. Although they are available without a prescription, we advise against using them without medical supervision. 52 Topical antifungal treatments for nails
