Adverse Reaction to Omalizumab in Patients with Chronic Urticaria: Flare Up or Ineffectiveness?
Abstract
Omalizumab is a recombinant humanized anti-Ig E monoclonal antibody used as the third line treatment of chronic spontaneous urticaria (CSU). We report four patients with severe antihistamine-resistant CSU, who developed angioedema, anaphylaxis and/or flare up of urticaria at different times following omalizumab therapy.
