Antifungal agents are medications used to treat fungal infections that affect areas of the body, such as the toes, groin, under the breasts, scalp or nails. These drugs are available in both topical (applied directly to the skin) and systemic (spread throughout the body) forms.

Antifungal agents are often used to treat candidiasis (yeast infections), fungal (mold-like) infections of hair, skin and nails, and tinea versicolor (a yeast-like organism). Topical agents are usually used to treat minor infections, whereas systemic agents are used to treat more serious skin infections and infections of the scalp and the nails.
