Important Safety Information and Indication

Important Safety Information

BeneFix is contraindicated in patients who have manifested life-threatening, immediate hypersensitivity reactions, including anaphylaxis, to the product or its components, including hamster protein.
Call your health care provider right away if your bleeding is not controlled after using BeneFix.
Allergic reactions may occur with BeneFix. Call your health care provider or get emergency treatment right away if you have any of the following symptoms: wheezing, difficulty breathing, chest tightness, your lips and gums turning blue, fast heartbeat, facial swelling, faintness, rash or hives.
Your body can make antibodies, called “inhibitors,” which may stop BeneFix from working properly.
If you have risk factors for developing blood clots, such as a venous catheter through which BeneFix is given by continuous infusion, BeneFix may increase the risk of abnormal blood clots. The safety and efficacy of BeneFix administration by continuous infusion have not been established.
Some common side effects of BeneFix are nausea, injection site reaction, injection site pain, headache, dizziness and rash.
