Does the Method of Discontinuation Influence Relapse?","authors":"Petek Üstün, Esra Adışen","doi":"10.5826/dpc.1503a5196","DOIUrl":"10.5826/dpc.1503a5196","url":null,"abstract":"<p><strong>Introduction: </strong>Omalizumab is recommended for chronic urticaria (CU) until spontaneous remission occurs rather than for a specific period of time.

Among the 109 patients who discontinued omalizumab directly, 65.1% experienced a relapse.
