Aquagenic urticaria, also known as water urticaria and aquagenous urticaria, is an extremely rare form of physical urticaria. It is sometimes described as an allergy, although it is not a histamine releasing allergic reaction like other forms of urticaria; it is more a hypersensitivity to the ions found in non-distilled water. In affected persons, water on the skin causes hives to appear within 15 minutes and last for up to two hours.
