Abstract
Biologic agents are a rapidly expanding class of medications, and several options are now available for the management of allergic and immunologic disorders. The risks of biologic therapy need to be understood in order to adequately counsel patients and appropriately monitor for potential adverse events. We sought to provide a comprehensive review of the risks and adverse effects reported for the current FDA-approved biologics used in management of allergic and immunologic disorders, including omalizumab, benralizumab, dupilumab, mepolizumab, reslizumab, tezepelumab and tralokinumab. Our review focuses on the risk of hypersensitivity reactions, pregnancy-specific considerations, risk of infection and risk of malignancy. We also highlight drug-specific adverse events and unique safety issues identified in case reports.
