Terbinafine (Lamisil) General Information
Terbinafine is a general-purpose antifungal product. It can cure common athlete’s foot, jock itch, and ringworm faster than other medicines of this type. It is also effective against Candida and other fungal infections of the skin. Terbinafine is unique because it accumulates in the skin after application and continues to kill fungus organisms even after you stop using it. Most other antifungals applied to the skin do not kill the fungus; they only stop it from growing. Because of its strength, Terbinafine may be prescribed for fungal infections of the skin that do not respond to nonprescription products.
