Background: Chronic idiopathic urticaria (CIU) impairs quality of life (QoL). Currently, no consensus exists regarding how second‐generation H 1 ‐antihistamines (proven to control CIU symptoms) should be taken long‐term: as daily treatment or only when symptoms return (PRN). We sought determine which regimen improves better maintains QoL in CIU: desloratadine (DL) PRN. Methods: Subjects with initially responding DL 5 mg/day for 4 weeks were randomized an additional 8 weeks, (arm 1:...
