Lamisil(Terbinafine) is used to treat certain types of fungal infections (e.g., fingernail or toenail). It works by stopping the growth of fungus. This medication belongs to a class of drugs known as antifungals.
Take Lamisil Tablets by mouth, usually once a day, or as directed by your doctor. It may be taken with or without food. Dosage and duration of therapy is based on your medical condition and response to therapy. It may take several months after completion of treatment to see the full benefit of this drug.
