Antifungals are medications used to treat infections caused by fungi. These infections can affect various parts of the body, including the skin, nails, and internal organs. Common antifungal medications include fluconazole, itraconazole, and clotrimazole, which work by inhibiting the growth of fungi or killing them outright. Antifungals can be administered in different forms, such as pills, creams, or injections, depending on the type and severity of the infection. It's important to use antifungals as prescribed by a healthcare professional to ensure effectiveness and reduce the risk of resistance, where fungi become less susceptible to treatment.
