If you decide to treat a fungal nail infection, you can try a nonprescription antifungal medicine that comes in a cream, lotion, or nail polish. Your doctor can also prescribe a stronger medicine. You may need to use this medicine for a few weeks or for as long as a year. Even so, it may not get rid of the infection.
Antifungal pills give the best chance of curing a severe fungal nail infection. But they may cost a lot and have serious side effects. You will need to see your doctor for regular testing if you take these pills.
Fungal nail infections often come back after treatment. It is important to take steps to prevent this.
Before bed, wash and dry your feet carefully.
Wear sandals or roomy shoes made of materials that allow moisture to escape. Let shoes dry for 24 hours before you wear them again.
Wear socks. Change them if your feet get sweaty.
Do not share nail files or clippers, socks, towels, or other personal items.
Wear flip-flops or shower sandals in wet public areas, such as locker rooms or showers.
