Question: How do I get rid of toenail fungus? It is a persistent problem for me.

Dr. Hibberd's answer:
An infection with nail fungus may be difficult to treat, and it may recur. Prescription medications are available to help clear up nail fungus, but they are expensive and often needed to be taken for 6-8 weeks. Over-the-counter antifungal nail creams and ointments are available, but they aren't very effective. The most effective treatments are oral medications, terbinafine (Lamisil) and itraconazole (Sporanox). Treating nail fungus with a laser or photodynamic therapy — intense light irradiates the nail after it's been treated with an acid — may also be successful. However, this new treatment may not be available everywhere. To prevent recurrence, follow good hand and foot hygiene. Trim nails straight across and file down thickened areas. Thoroughly dry your hands and feet, including between your toes, after bathing. Wear appropriate socks and change them often, especially if your feet sweat excessively. Take your shoes off occasionally during the day and after exercise and air your feet out, as fungi love to grow in warm , moist toe areas. Alternate closed-toe shoes with open-toe shoes. You might spray or sprinkle your feet with antifungal powder as a growth deterant also.
