FIRAZYR works by blocking bradykinin from binding to B2 receptors, which reduces the activity of bradykinin and thereby treats the symptoms of acute attacks of HAE.

FIRAZYR is for adults 18 years or older with HAE. Before using FIRAZYR, tell your healthcare provider if you are pregnant or nursing or if you have any other medical conditions, because these conditions could affect your treatment. Learn more »

Most people with HAE don’t have enough of a protein called C1 esterase inhibitor, or this protein does not work as it should, which contributes to a cascade of events in the body. This cascade causes another protein called plasma kallikrein to trigger the release of a third protein called bradykinin. Having too much bradykinin causes the blood vessels to release fluid, resulting in localized swelling.

FIRAZYR works by blocking bradykinin from binding to B2 receptors, which reduces the activity of bradykinin and thereby treats the symptoms of acute attacks of HAE.

FIRAZYR should be taken when you recognize the symptoms of an HAE attack. FIRAZYR should be administered as a slow injection, over at least 30 seconds, under the skin in the stomach (abdomen) area. Learn more »
