Background Patients who have failed traditional treatment of chronic urticaria may require trials of alternative medications. Safety profiles, continuous laboratory monitoring, and physician comfort are often barriers to treatment. Objectives To evaluate the safety of alternative agents used in chronic urticaria. Methods A retrospective chart review of electronic medical records from a single-center allergy and immunology clinic in a major academic hospital was conducted. One hundred twenty-six charts of patients with chronic urticaria treated with alternative agents were reviewed. Results Adverse effects were reported in 39 of 73 (53%) patients on dapsone, 19 of 47 (40%) patients on sulfasalazine, 15 of 36 (42%) patients on tacrolimus, 7 of 45 (16%) patients on hydroxychloroquine, 9 of 27 (33%) patients on mycophenolate, 6 of 8 (75%) patients on cyclosporine, and 3 of 24 (4%) patients on omalizumab. Most of these adverse effects were mild, did not require discontinuation of the medication, and resolved after stopping the medication or decreasing the dose. Conclusions The use of alternative agents for the treatment of chronic urticaria angioedema is generally safe when proper laboratory and clinical monitoring is observed.
