Brand name(s)
Rebinyn

This medication is used to prevent, treat, and control bleeding episodes in people with little or no factor IX (due to hemophilia B, Christmas disease). Factor IX is a protein normally found in the blood that helps the blood to thicken (clot) and 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 contains a man-made form of factor IX.

This medication is given by injection into a vein over several minutes as directed by your doctor. After first receiving this medication in a hemophilia treatment center or hospital, some people may be able to give it to themselves at home. If your doctor directs you to use this medication at home, read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start using this medication and each time you get a refill. Learn all preparation and usage instructions in the product package. Learn how to store and discard medical supplies safely. If you have any questions, ask your health care professional.

The medication in the vial and the supplies that come with the medication should be used only once. Do not reuse. If the medication and the solution used to mix it were refrigerated, bring both to room temperature before mixing. After adding the solution to the powder, gently swirl the mixture to completely dissolve the powder. Do not shake. Before using, check this product for particles or discoloration. If either is present, do not use the liquid.

The dosage is based on your medical condition (amount and location of bleeding), weight, and response to treatment.
