There are several good treatments for white toenail fungus, including debridement, oral medication, topical medication and over-the-counter medication, says Everyday Health. Medicated nail polish, such as Penlac may be prescribed by a doctor to use daily, reports Mayo Clinic. The most effective doctor-prescribed pills include Lamisil and Sporanox.
White superficial onychomycosis is a fungal infection of the nail surface that causes white patches to form on the nail, notes Everyday Health. People can file these patches away and apply antifungal ointment to the nail. OTC antifungal products, such as Fungoid Tincture, are effective, but require multiple applications to penetrate the nail.
