There are a number of different treatments for nail fungus that can be effective, depending on the type of fungus and the severity of the infection. For mild to moderate infections, over-the-counter anti-fungal creams and gels may help eliminate the infection, according to WebMD.
Another possible treatment that may help with less severe infections is applying an anti-fungal nail polish. In addition to potentially killing the fungus, these treatments may also prevent it from returning and stop athlete's foot from spreading to the nails.
For more severe fungal infections, most doctors prescribe oral antifungal pills. These usually offer a much better chance at treating the fungus and are also recommended for hard to treat cases. In some extreme cases, the doctor may decide that the entire nail needs to be removed, which can be done either surgically or non-surgically.
Prior to 2014, the only prescription medications available for nail fungus were in pill form. However, in June 2014, the U.S. Food and Drug Administration approved the first prescription topical treatment for nail fungus. This medication, known as Jublia, is a liquid that can be applied directly to the nail to treat a specific type of nail fungus known as onychomycosis.
