Fungal skin infections often cause itching, redness, rashes, burning, or dark patches. These symptoms can get worse in hot weather, with sweating, or if the skin stays damp. Medicines like Itraconazole, Fexofenadine, and Onabet are commonly used to treat these infections and help with itching. You may start to feel better gradually, but how quickly you improve depends on how bad or widespread the infection is. Many people notice less itching and redness after a couple of weeks, but you might need to keep using the medicine longer to stop the infection from coming back. It is important to keep the area dry and clean. Try to wear loose cotton clothes, avoid sweating for long periods, and do not scratch the skin, as this can slow down healing. If you miss doses or stop treatment too soon, the infection may return. Be sure to follow your doctor?s instructions, and see your doctor again if the rash spreads, becomes painful or develops pus, or if it does not get better after the treatment period.
