The fungal infection is often treated with topical antifungal agents, which can take the form of a
spray, powder, cream, or gel. The most common ingredients in over-the-counter products are miconazole nitrate (2% typical concentration in the United States) and tolnaftate (1% typ. in the U.S.). Terbinafine, marketed as Lamisil is another over-the-counter drug.
