Why is this medication prescribed?
Cinryze is prescribed primarily for the prophylactic treatment of hereditary angioedema (HAE) in adolescents and adults. Hereditary angioedema is a genetic condition that causes recurrent episodes of swelling in various parts of the body, including the hands, feet, face, and airway.
How should this medicine be used?
How Cinryze is used:
- Dosage: The typical dosage of Cinryze for routine prophylaxis is 1000 units (one vial) administered intravenously every 3 or 4 days.
- Administration: It is administered as an intravenous (IV) infusion over a period of about 10-15 minutes. It should be administered under the supervision of a healthcare professional experienced in the treatment of hereditary angioedema.
- Monitoring: Patients may need to be monitored for a short period after administration to watch for any adverse reactions.
- Prophylactic Use: Cinryze is used on a regular basis to prevent attacks of hereditary angioedema rather than to treat acute attacks. It helps to reduce the frequency, severity, and duration of attacks.
- Instructions: Patients should be instructed on the proper technique for preparing and administering Cinryze, as well as the importance of adhering to the prescribed dosing schedule.
- Storage: Cinryze should be stored in a refrigerator at a temperature of 2°C to 8°C (36°F to 46°F). Do not freeze.
It’s crucial for patients to communicate with their healthcare provider regarding any concerns or side effects experienced during treatment with Cinryze.
Other uses for this medicine
Apart from its primary use in the prophylactic treatment of hereditary angioedema (HAE), Cinryze is not typically used for other medical conditions due to its specific mechanism of action and indication. It is specifically designed to prevent attacks of HAE rather than treat other types of swelling or allergic reactions.

Special precautions for Cinryze:
- Allergic Reactions: Patients should be monitored for signs of allergic reactions during and after administration. Although rare, severe allergic reactions can occur.
- Thromboembolic Events: There have been reports of thromboembolic events (such as blood clots) in patients receiving Cinryze. Caution should be exercised in patients with a history of clotting disorders or conditions that may predispose them to clot formation.
