How does the Apo-Ketoconazole medication work? What will it do for me?
Ketoconazole belongs to the family of medications called antifungals. It is used to treat certain types of serious fungal infections. Ketoconazole is used to treat both internal (in the body) and external (on the skin) fungal infections. Ketoconazole works by preventing the fungus from making normal cell walls, thereby stopping fungal growth.
