Swimmer's itch typically clears up on its own within a few days, though in some cases the rash can last up to a week. In the meantime, you can control itching with over-the-counter antihistamines or anti-itch creams, such as those that contain calamine lotion. If the itching is severe, your doctor may recommend a prescription medication.
