HAEGARDA SAFETY AND SIDE EFFECTS

Allergic reactions may occur with HAEGARDA. You should not use HAEGARDA if you have experienced life-threatening immediate hypersensitivity reactions, including anaphylaxis, to the product.

Blood clots have occurred in patients receiving HAEGARDA. Very high doses of C1-INH could increase the risk of blood clots.

Because HAEGARDA is made from human blood, it may carry a risk of transmitting infectious agents, e.g., viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

Do not attempt to self-administer unless you have been taught how by your healthcare provider.

This information does not take the place of talking with your healthcare provider, and it does not include all of the important information about HAEGARDA. If you have any questions, ask your healthcare provider.

The most common side effects with HAEGARDA are injection-site reactions (pain, redness, swelling), hypersensitivity (itching and rash), nasopharyngitis (runny or stuffy nose, sneezing, watery eyes) and dizziness. These are not all the possible side effects of HAEGARDA.
