Is Icatibant Safe for the Treatment of Hereditary Angioedema During Pregnancy?

Purpose Of Review: Hereditary angioedema (HAE) is a disorder affecting bradykinin regulation presenting as recurrent cutaneous or mucosal swelling. Treatment options include plasma-derived or human-recombinant C1-inhibitor, icatibant, or ecallantide. Due to the lack of knowledge and experience on the topic, the treatment of choice in pregnancy is plasma-derived C1-inhibitor, and reporting any new experience is recommended. This review presents current guidelines for HAE treatment with a focus on pregnancy and reviews all experience with icatibant use during pregnancy.

Recent Findings: Our experience of treating a pregnant nC1-INH HAE patient with icatibant is presented, with no adverse effects or abnormalities, to add to the growing knowledge of icatibant use during pregnancy. Considering the limited number of attacks that our patient usually experiences, which continued at more or less the same frequency during pregnancy, we feel icatibant to be a safe choice for on-demand HAE treatment during pregnancy for such cases.
