Treatment of Hives: Loratadine (claritin, 10 milligrams) and fexofenadine (allegra) are antihistamines available over the counter that are less likely to cause drowsiness. Also approved for over-the-counter use is Hydroxyzine (atarax, vistaril), which causes drowsiness, and its breakdown product, Cetirizine (zyrtec, 10 milligrams), which is slightly sedating. It is best to determine the cause of the hives.
