Coagulation factor X

Coagulation factor X (10) is a man-made protein that is similar to a natural protein in the body that helps blood clot.

Coagulation factor X is used to treat or prevent bleeding in people with hereditary factor X deficiency. This medication is for adults and children.

Coagulation factor X may also be used for reasons not mentioned in this medication guide.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Coagulation factor X is given as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Coagulation factor X must be mixed with a liquid (diluent) before using it. When using injections by yourself, be sure you understand how to properly mix and store the medicine.

Gently swirl but do not shake the medicine. The mixture should appear clear or slightly pearl-like. Do not use the mixed medicine if it looks cloudy or has particles in it. Prepare a new kit or call your pharmacist for a new kit.

Prepare your dose only when you are ready to give an injection. Use the injection within 1 hour after mixing your dose.

You will need frequent medical tests.

Tell your doctor if this medicine seems to stop working as well in preventing a bleeding episode.

You may store this medicine at room temperature or in a refrigerator. Protect from light and do not freeze. Keep the injection kit in its original package until you are ready to prepare an injection.

Throw away any unused coagulation factor X after the expiration date on the medicine label has passed.

Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

Follow all instructions on your medicine label and package. Inform each of your healthcare providers about all your medical conditions, allergies, and all medicines you are using.

You should not use coagulation factor X if you have had an allergic reaction to clotting factor medicine.

Do not give this medicine to a child without medical advice.

Tell your doctor if you are pregnant or breastfeeding.

Coagulation factor X is made from donated human plasma and may contain viruses or other infectious agents. Donated plasma is tested and treated to reduce the risk of contamination, but there is still a small possibility it could transmit disease. Ask your doctor about any possible risk.
