Fungal nails refer to any number of fungal nail infections that can occur on the foot. More aggressive and challenging to treat than Athlete’s Foot, your physician may prescribe a topical or oral antifungal medication. Persistent fungal nails may need to be removed.

Note: Please consult a physician before taking any medications.

Preventing Fungal Nail Infections

In order to avoid an infection from recurring, please follow the proper preventative measures. This will help to keep fungi at bay, an important step in preventing a repeat nail infection. Carefully wash and dry your feet before bed, and apply a nonprescription antifungal cream to the entire foot from the ankle down. Repeat every night and progressively apply less and less cream. It’s crucial to dry your feet well because dry skin is less likely to become infected. Apply powder to your dry feet after showering or taking a bath.

Other suggestions for preventing fungal nails include:

  • Don’t share nail clippers or nail files.
  • Don’t share shoes or socks.
  • Try not to injure your nail (i.e. by cutting it too short) as trauma to the nail may lead to infections.
  • Wear dry cotton socks and change them two or three times a day if necessary.
  • Wear dry shoes that allow for air circulation around your feet. Confined, cramped, and moist shoes contribute to fungal toenail infections.
  • Wear shower sandals or shower shoes when using a public pool or shower.


Maintaining basic foot care guidelines will most likely control most common foot fungus problems.
