Hello,
The mainstay of treatment of hives is antihistamine which may be necessary
for prolonged periods (in excess of 6 weeks). Double conventional doses of these
non-
sedating antihistamines such as Cetirizine, Loratadine, Acrivastine and Fexofenadine may be needed to get symptom relief. Sedating antihistamines such as Chlorphenamine or Hydroxyzine are used at night to get urticaria control.
