How is CINRYZE Administered?

CINRYZE is administered by intravenous (or IV) injection, meaning it is injected into a vein in your arm. You can choose to have your injection administered by a healthcare provider or caregiver, or a healthcare provider can show you how to give it to yourself. This is called self-administration. A healthcare provider can also train a parent or caregiver to administer CINRYZE to a child.

Do not try to self-administer CINRYZE until a healthcare professional has taught you or a caregiver how.

CINRYZE is used every 3 or 4 days for prevention of hereditary angioedema (HAE) attacks. It's important that you work closely with your healthcare provider to create a prophylactic therapy regimen that's right for you.
