Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
This medication comes with patient instructions for safe and effective use. You will need to use two vials of Cinryze to make up a single dose. Follow all directions carefully. Ask your doctor or pharmacist if you have any questions.
Cinryze is usually given every 3 or 4 days to prevent angioedema attacks. An IV infusion takes about 10 minutes to complete.
