Nailrox (Ciclopirox Olamine 8% w/v) is a topical antifungal solution, commonly formulated as a nail lacquer, primarily used to treat mild to moderate fungal infections of the fingernails and toenails (onychomycosis) in people with healthy immune systems. It is specifically effective against infections caused by the fungus Trichophyton rubrum that do not involve the nail lunula (the white “half-moon“ at the base of the nail).
