Haegarda is a prescription medication used to prevent hereditary angioedema attacks. Haegarda is a C1 esterase inhibitor that works to block a substance that causes inflammation and swelling in the body. 

Haegarda is an injection given just below the skin every 3-4 days. Do not attempt to self-administer unless you have been taught how by your healthcare provider.

Common side effects of Haegarad include reactions at the site of injection, strep throat, and dizziness. 

Haegarda is an injectable prescription medicine used to prevent swelling and/or painful attacks in adults and adolescents with Hereditary Angioedema (HAE). HAE is caused by the poor functioning or lack of a protein called C1 that is present in your blood and helps control in ammation (swelling) and parts of the immune system. HAEGARDA contains C1 esterase inhibitor (C1-INH), a protein that helps control C1.

Haegarda should not be used to treat an acute HAE attack. In case of an acute HAE attack, initiate individualized treatment as discussed with your prescribing health care professional. 

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.
