Question: how to get rid of fungus under fingernail?
Answer: Oral antifungal drugs. Options include terbinafine (Lamisil) and itraconazole (Sporanox). These drugs help a new nail grow free of infection, slowly replacing the infected part. You typically take this type of drug for six to 12 weeks. But you won't see the end result of treatment until the nail grows back completely.
