Anti-fungal gels and creams and nail polish all work well in treating nail fungus, according to WebMD. Such treatments also reduce the risk of a return infection and may prevent athlete's foot from moving to the nails.
Over-the-counter treatments are effective at eliminating most minor to moderate cases of nail fungus, explains WebMD. A physician may recommend prescription pills for hard-to-treat symptoms that persist; a topical or oral antibiotic may also be prescribed when a bacterial infection accompanies the fungal infection. In severe cases, the doctor may opt to remove the nail surgically or non-surgically if all other treatments have failed.
