BeneFIX IV Warnings
BeneFIX IV Uses
This medication is used to prevent or control bleeding in people with little or no factor IX (due to hemophilia B, Christmas disease). Factor IX is a protein (clotting factor) in the blood that works with other clotting factors to help the blood clot and therefore stop bleeding. People with little or no factor IX are at risk for bleeding longer after an injury/surgery or bleeding suddenly (often in the joints/muscle) without an obvious cause.
This medication should not be used to treat other types of factor deficiencies (e.g., factors II, VII, VIII, X) or factor problems (e.g., inhibitor to factor XIII), to reverse the effects of "blood thinners" (e.g., warfarin), or to treat bleeding from low levels of liver-dependent clotting factors (due to liver problems).How to use BeneFIX IV
Read the Patient Information Leaflet if available from your pharmacist before you start using factor IX and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
This medication is given by injection into a vein over several minutes as directed by your doctor. Dosage is based on your medical condition (e.g., amount and location of bleeding), weight, and response to treatment.
If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

For some brands, it is important to limit the amount of blood entering the tubing and to avoid letting any blood enter the syringe. You may need to use a new vial of medication and new set of supplies if this occurs. Consult your pharmacist for details.
