Potential side effects of FIRAZYR
FIRAZYR is used to treat acute attacks of hereditary angioedema (HAE) in adults 18 years of age and older.
The most common side effects of FIRAZYR include:
- Redness, bruising, swelling, warmth, burning, itching, irritation, hives, numbness, pressure or pain at the injection site
- Too much of an enzyme called transaminase in your blood
In a self-administration study, 56 patients with HAE treated themselves with FIRAZYR. The safety profile of FIRAZYR was about the same, regardless of whether patients gave the injection themselves or had it done by a healthcare professional.
Tiredness, drowsiness and dizziness have been reported following the use of FIRAZYR. If any of these occur, do not drive a car, use machinery or do anything that needs you to be alert.
In clinical trials, no hypersensitivity or anaphylactic reactions were reported.
Tell your healthcare provider if you have any side effect that bothers you or that does not go away. For more information about FIRAZYR, ask your healthcare provider. For further information, please see the full Prescribing Information.
