Lamisil is used to treat fungal infections of the feet, also known as athlete's foot. It is used to relieve itching, irritation, and cracking caused by this infection. It also treats tinea corporis and tinea cruris, two types of fungal infections that cause a skin rash that may be itchy and red. It also treats fungal infections of the nails, a condition known as onychomycosis. The medicine works by eliminating the fungus and gradually improving nail health.
Lamisil is sometimes used to treat other fungal infections that affect different areas of the body, such as the scalp. It also relieves inflammation associated with fungal skin infections, as it helps reduce itching and swelling and prevents the condition from worsening.
