1. What are the uses of Corifact?

1.1. What is Corifact? Corifact belongs to the group of anticoagulant drugs, is an exclusive registered trademark of CSL Behring GmbH Pharmaceutical company - USA.
1 Corifact box contains:
Active ingredient: Factor XIII concentrate 1000-1600 units. Sterile water for injection 1 tube 20ml. The Corifact Mix2 Vial filter adapter is recommended for adult use.
1.2. What does Corifact do?
Corifact is prescribed for use as a prophylactic and therapeutic drug to prevent bleeding episodes in people with an inherited bleeding disorder caused by factor XIII deficiency. Factor XIII is a naturally occurring protein in the blood that helps blood to clot. Patients with factor XIII deficiency are still able to form clots, but the clot's texture is unstable and begins to rupture 24 to 48 hours after formation. Without factor XIII, the fibrin fibers are only loosely organized and cannot crosslink, so clots are easier to dissolve. The rapid breakdown of the clot leading to bleeding episodes is typical of factor XIII deficiency. Corifact works by temporarily raising the levels of these factor XIII in the blood to aid in blood clotting.
Contraindications to taking Corifact:
Patients are allergic to the main active ingredient Factor XIII or any of the excipients of the drug. Persons with known severe anaphylactic or systemic reactions to products derived from human plasma.

Management of intraoperative bleeding:
Dosage must be individualized based on the patient's FXIII activity level, type of surgery, and clinical response. Monitor patient's FXIII activity level during and after surgery. Guidelines for dose adjustment for preoperative management.

3. Notes when using Corifact

Corifact is usually taken about once a month, depending on the patient's recent blood test results. Reconstituted Corifact should be clear or slightly yellow in color. Do not use the medicine if it has changed color or there is a precipitate in the vial. Corifact is made from human plasma, which may contain viruses and other infectious agents. Donated plasma has been tested and processed to reduce the risk of containing an infectious agent, but there is still a very small chance that it may still contain pathogens and possibly be an intermediary. Corifact can increase a person's risk of blood clotting problems. Tell your doctor right away if you have a sudden or severe headache, problems with your voice or vision, trouble breathing, chest pain, or numbness in your limbs while you are taking this medicine. If signs or symptoms of anaphylaxis or hypersensitivity reaction (including rash, urticaria, chest tightness, wheezing, hypotension) occur, discontinue use immediately. Inhibitors against FXIII have been detected in patients receiving Corifact. Patients should be monitored to control the development of inhibitory antibodies. The presence of inhibitory antibodies may manifest as an inadequate response to treatment. If the expected level of FXIII plasma activity is not achieved or if sudden bleeding occurs during prophylactic therapy, perform an FXIII inhibitory antibody test. Thromboembolic complications have been reported with the use of Corifact. Monitor patients with known risk factors for thrombotic events. Not intended for use by pregnant and lactating women.
