Lamisil is used to treat a variety of skin and fungal infections that affect the body. It is particularly effective in treating ringworm, a fungal skin infection that appears as circular red spots; treating nail fungus that affects the fingernails and toenails; relieving the symptoms of athlete's foot, which include itching and cracking of the skin of the feet; and treating ringworm of the skin and groin, which causes itching and irritation in sensitive areas.
Lamisil works by inhibiting the growth of fungi and preventing their reproduction, which helps the body gradually eliminate them. It is best to use it based on a doctor's recommendation to ensure the appropriate dosage and avoid any potential side effects.
