Examples of over-the-counter antifungal creams include Lotrimin AF Antifungal Athlete's Foot Cream, Lamisil AT, Micatin and Tinactin Antifungal Cream. For best results, choose a cream specially formulated for the type of fungus infection being targeted.
Fungal infections may manifest themselves as ringworm, athlete's foot, tinea versicolor, nail fungus or jock itch. Among the active ingredients found in over-the-counter antifungal medications are clotrimazole, miconazole, terbinafine, tolnaftate and undecylinic acid. Most of these topical agents need to be used for several weeks to be effective, but terbinafine, which is the active ingredient in Lamasil, is typically used for only one to two weeks. When over-the-counter medications prove ineffective, prescription medication is often necessary.
