Firazyr is a prescription medication used to treat attacks of hereditary angioedema (HAE), an immune system disorder, in adults 18 years and older. Firazyr belongs to a group drugs called bradykinin B2 receptor antagonists. It works by blocking bradykinin, a substance which is believed to be responsible for the HAE symptoms of inflammation, swelling, and pain.
This medication comes as a pre-filled syringe to be injected under the skin in the abdominal area. Doses should be administered in intervals of at least 6 hours. No more than 3 doses should be taken in a 24 hour period.
The most common side effects include fever, dizziness, nausea, and irritation at the injection site. Do not drive or operate heavy machinery until you know Firazyr affects you.
