Apply to the skin, 2 times a day. Avoid contact with the eyes. Therapy for a period of 2-3 weeks is usually sufficient; however, treatment for 4-6 weeks may be necessary, especially if thickening of the skin has occurred. Treatment should be continued for 2 weeks after symptoms have disappeared. Tolnaftate may be used concurrently with an oral antifungal agent eg, griseofulvin, in the treatment of onychomycosis or chronic infections of the scalp, palms or skin.
