J Allergy Clin Immunol Pract. 2026 Feb;14(2):375-383. doi: 10.1016/j.jaip.2025.11.039.

Abstract

Hereditary angioedema (HAE) with C1-inhibitor deficiency is a rare condition presenting with episodes of swelling without urticaria. Historically, acute and prophylactic HAE treatment options were limited and associated with considerable side effects, high burden of treatment, and unreliable symptom relief. Over the past decade, newer targeted therapies have been investigated and approved for both acute therapy and long-term prophylaxis. These therapies have dramatically reduced morbidity and mortality of HAE and consequently improved the quality of life of patients. This review article will outline the current and potential future treatments for HAE.
