Medications for nail fungus are used to treat fungal infections of the nails. Some of these medications can also treat other fungal infections, like athlete's foot, jock itch, and ringworm. They work by either killing the fungus or stopping its growth. Common classes include antifungals. Antifungals like terbinafine are usually taken as oral pills, while topical solutions like tavaborole (Kerydin) and Jublia (efinaconazole) are applied directly to the nails. These options provide different ways to help manage and treat fungal infections effectively.
