Firazyr is a bradykinin B2 receptor antagonist and is used to treat treatment of sudden attacks of hereditary angioedema (HAE).

Firazyr is a bradykinin B2 receptor antagonist. It works by blocking the activity of a natural substance in the body called bradykinin. Bradykinin causes blood vessels to dilate (widen) and lead to swelling. In HAE, there’s too much bradykinin produced in your body, which causes severe swelling in different parts of your body (hands, feet, stomach, face, throat). By blocking bradykinin, Firazyr can help lower pain and swelling from an HAE attack.

Firazyr is typically started at 30 mg injected under the skin (subcutaneous) in the stomach area. If needed, additional doses can be given at least 6 hours apart, with a maximum of 3 doses in 24 hours.

Firazyr is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects. You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you.
