Treatment for nail fungus
may include antifungal medicine and topical treatments. Antifungal medicine is a pill that treats a fungal infection. You may need to take this medicine for up to 12 weeks. Topical treatments include creams and polishes that you apply to the top of your nail. You may need to use topical treatments for up to 1 year before you see positive results. Ask your healthcare provider for more information about antifungal medicine.
Manage your symptoms:
- Use antifungal sprays or powders. You can buy these at your local drugstore.
- Keep your nails short and file down any thick areas. Use separate nail trimmers and files for infected nails and healthy nails. If you go to a salon to get your nails done, bring your own nail files and trimmers.
Prevent nail fungus:
- Dry your feet with a towel or hair dryer after you bathe.
- Do not wear tight-fitting shoes or shoes that pinch your toes. Avoid shoes made from rubber or plastic.
- Wear socks that absorb moisture. This includes socks make of wool, nylon, or polypropylene. Do not wear cotton socks. Change your socks if they are damp from sweat or your feet get wet. Put on dry, clean socks every day.
- Do not go barefoot in locker rooms or public showers.
- Do not use nail polish or artificial nails such as acrylic or gel nails.
- Wear gloves that are waterproof if you work with water.
