This medication is used to treat a variety of fungal skin infections such as ringworm, athlete's foot, and jock itch. This medication is also used to treat a skin condition known as pityriasis (tinea versicolor), a fungal infection that causes a lightening or darkening of the skin of the neck, chest, arms, or legs. Terbinafine is an antifungal that works by preventing the growth of fungus.
Use this medication on the skin only. Clean and thoroughly dry the area to be treated. Apply a thin layer of the medication on and around the affected area, usually once or twice daily as directed on the product package. If you are uncertain about any of the information, consult your doctor or pharmacist. Wash your hands after using unless the area being treated includes the hands.
