Portable HAE treatment designed with patients in mind

Here you will find important information about FIRAZYR, a medicine used to treat acute attacks of hereditary angioedema (HAE) in adults 18 years of age and older. FIRAZYR is the first and only FDA-approved injection you give yourself under the skin (subcutaneously) to treat acute attacks of HAE—both in and out of the home—after you have been trained by a healthcare professional.


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.
