Using an antifungal can be a good thing if you have a fungal infection. Fungal infections can occur on the skin, nails, or inside your body and can be uncomfortable and even harmful if left untreated. Antifungal medications work by killing the fungus causing the infection or preventing it from spreading. If you are experiencing symptoms such as itchiness, burning, or discoloration, it is important to see a healthcare provider who can diagnose the infection and recommend the appropriate antifungal treatment. However, it is important to use antifungal medications as prescribed by your healthcare provider and to complete the full course of treatment to effectively cure the infection.
