Cinryze is used to prevent angioedema attacks in people with hereditary angioedema (HAE). Do not self-inject Cinryze unless you have been taught how to by your physician.
Cinryze is a prescription medication used to prevent angioedema attacks in adults and adolescents with hereditary angioedema (HAE). Cinryze belongs to a class of medications called recombinant serine proteinase inhibitors. These work to prevent angioedema attacks by reducing the permeability of certain small blood vessels.
This medication is available in an injectable form to be given directly into a vein and is typically given every 3 or 4 days.
Common side effects of Cinryze include headache, nausea, and rash.
Cinryze can also cause dizziness. Do not drive or operate heavy machinery until you know how Cinryze affects you.

Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Cinryze falls into category C. There are no well-controlled studies that have been done in pregnant women. Cinryze should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.
Cinryze and Lactation

You should always follow the specific instructions given by your healthcare provider. The steps listed below are general guidelines for using Cinryze. If you are unsure of the steps, please call your healthcare provider or pharmacist before using.
Preparation of Cinryze
Always wash your hands before doing the following steps. Try to keep everything clean and germ-free while you are reconstituting Cinryze. Once you open the vials, you should finish preparing Cinryze as soon as possible. This will help to keep them germ-free.
Note: Two vials of Cinryze are required for each dose. You should reconstitute both vials according to steps 1 through 6.
Let the vial of Cinryze and the vial of Sterile Water for Injection, USP (diluent) reach room temperature.
Remove the cap from the vial of Cinryze and Sterile Water for Injection, USP (diluent) vial to show the center part of the rubber stopper.
Wipe the top of each vial with an alcohol wipe or swab, and allow it to dry. Do not blow on the stopper to dry it faster. Place each vial on a flat surface. After cleaning, do not touch the rubber stopper with your hand or allow it to touch any surface.
Note: Diluent vial must be penetrated before the Cinryze vial to prevent loss of vacuum.Remove the protective covering from the top of the Mix2Vial transfer device package. Do not remove the device from the package. Place the Sterile Water for Injection, USP (diluent) vial on a flat surface, and place the blue end of the Mix2Vial transfer device over it, pushing down until the spike penetrates the rubber stopper and the device snaps in place. Mix2Vial transfer device must be positioned completely upright before penetrating the rubber stopper. Remove the plastic package and discard it. Take care not to touch the exposed end of the device.
Place the vial of Cinryze on a flat surface. Turn the diluent vial containing 5 mL Sterile Water for Injection, USP, upside-down and insert the clear end of the Mix2Vial transfer device into the vial of Cinryze, pushing down until the spike penetrates the rubber stopper and the device snaps in place. The Mix2Vial transfer device must be positioned completely upright before penetrating the rubber stopper. The Sterile Water for Injection, USP, will automatically flow into the vial of Cinryze because the vacuum in the vial will draw the Sterile Water for Injection, USP, into the vial of Cinryze. If this does not happen, do not use the product.
Once all the Sterile Water for Injection, USP, is in the Cinryze vial, gently swirl (do not shake) the vial of Cinryze until all the powder is dissolved. Disconnect the Sterile Water for Injection, USP vial by turning it counterclockwise. Do not remove the clear end of the Mix2Vial transfer device from the vial of Cinryze.
Look at the final solution before using it to make sure that Cinryze is completely dissolved. The solution should be clear with no evidence of cloudiness. Reconstituted solution should be colorless to slightly blue. Do not use if solution is cloudy or otherwise discolored.
One vial of dissolved Cinryze contains 5 mL of C1 esterase inhibitor at a concentration of 100 Units/mL. Prepare two vials of Cinryze for one dose. Repeat steps 1-6 using a new Mix2Vial transfer device. Do not reuse the Mix2Vial transfer device. Cinryze should be administered within 3 hours of reconstitution.
Utilizing a sterile, disposable 10mL syringe, draw back the plunger to allow approximately 5mL of air into the syringe. Use of a silicone-free syringe is recommended.
Attach the syringe onto the clear end of the Mix2Vial transfer device by turning it clockwise.
Turn the vial of Cinryze upside down, inject air into the vial. Slowly pull as much dissolved Cinryze as possible into the syringe. While holding the vial upside down, detach the syringe from the vial by turning it counterclockwise and releasing it from the Mix2Vial transfer device. Remove any air bubbles by gently tapping the syringe with your finger and slowly pushing the air out of the syringe.
Repeat steps 7-9 above with a second vial of Cinryze to make one complete dose of 10 mL.
Dispose of the vials with the Mix2Vial transfer device attached to them.
Cinryze should be administered at room temperature promptly after preparation in the syringe.
Your healthcare provider will teach you how to safely administer Cinryze. It is important that Cinryze is injected directly into a superficial vein and not injected into surrounding tissues and not injected into an artery. Once you learn how to self-administer, you can follow these instructions.
Attach a needle or infusion set with a winged adapter to the syringe containing the dissolved Cinryze solution. Fill the tubing with dissolved Cinryze by gently pushing the plunger of the syringe. Be careful not to spill the dissolved Cinryze. This process replaces the air in the tubing with dissolved Cinryze.
Apply a tourniquet and prepare the injection site by wiping the skin well with an alcohol swab.
As instructed by your healthcare provider:
Insert the butterfly needle of the infusion set tubing into your vein.
Remove the tourniquet.
Make sure that the needle is in a vein.
Inject the dissolved Cinryze product slowly over ten minutes (approximately 1mL/min).
After infusing Cinryze, remove the infusion set and discard. Cover infusion site with an adhesive bandage. The amount of drug product left in the infusion set will not affect your treatment. Dispose of all unused solution, the empty vials, and the used needles and syringe in an appropriate container used for throwing away waste that might hurt others if not handled properly.
If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of Cinryze at the same time.
Take this medication exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.
