Coagulation factor IX is made from human plasma (part of the blood) which may contain viruses and other infectious agents.

Talk with your doctor about the risks and benefits of using this medication.
How should I use coagulation factor IX?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Your doctor may want to give your first dose of this medicine in a hospital or clinic setting to quickly treat any serious side effects that occur.
Coagulation factor IX is injected into a vein through an IV. You may be shown how to use an IV at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of needles, IV tubing, and other items used.
Coagulation factor IX is a powder medicine that must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.
The mixture should appear clear, yellow, or colorless. Do not use the mixed medicine if it has changed colors or has particles in it. Prepare a new kit or call your pharmacist for a new supply of coagulation factor IX.
Gently swirl but do not shake the medicine bottle when mixing or you may ruin the medicine. Use the injection within 3 hours after mixing your dose.
Coagulation factor IX comes with patient instructions for proper mixing and storage. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
Use a disposable needle only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
While using coagulation factor IX, you may need frequent blood tests.
If you store this medicine at home, carefully follow the directions on your medicine label about how to store the powder medicine and the diluent. Some forms of coagulation factor IX can be stored at room temperature, and others should be kept in a refrigerator. Do not freeze. Avoid exposing the medication to light.
Each single-use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.
Throw away any coagulation factor IX not used before the expiration date on the medicine label.
