You may receive this medication at a hemophilia treatment center, at your healthcare provider’s office or in your home. You should be trained on how to do infusions by your healthcare provider or hemophilia treatment center.

Many people with coagulation factor deficiencies learn to infuse their treatment by themselves or with the help of a family member.

• Inject coagulation Factor X when the first sign of bleeding occurs, before surgery as a precaution, and before the onset of menstrual bleeding, if appropriate and advised by your healthcare provider.
• Repeat the injection at intervals of 24 hours to stop the bleeding. Each individual bleed should be judged on its own severity.

Your healthcare provider will tell you how much coagulation Factor X to use based on your weight, the severity of your Factor X deficiency, and where you are bleeding. You may need blood tests done after using coagulation Factor X to be sure that your blood level of Factor X is high enough to clot your blood.

Call your healthcare provider right away if your bleeding does not stop after using this medication.

You must carefully follow your healthcare provider's instructions regarding the dosing and administration for infusing this medication so that your treatment will work best for you.

If you administer too much coagulation Factor X, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.
