Factor Ix Complex Dosage
Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Factor IX is injected into a vein through an IV. You may be shown how to use an IV at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.
Always check the strength of the medicine on the label to be sure you are using the correct potency.
Always wash your hands before preparing and giving your injection.
Factor IX 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. Take the medicine and diluent out of the refrigerator and allow them to reach room temperature before mixing your dose. Do not heat the medicine or diluent.
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.
After mixing, gently swirl the mixture and allow the medicine to completely dissolve. The mixture should be kept at room temperature and must be used within 3 hours. Do not put mixed medicine into the refrigerator.
Prepare your dose in a syringe only when you are ready to give yourself an injection. Do not use the medication if it has changed colors or has particles in it. Call your pharmacist for new medication.
A single dose of factor IX may be enough to control minor bleeding. If you need another dose, wait at least 24 hours before using the medication again.
Check your pulse before and during your injection. If your pulse rate changes, slow or stop the injection until your pulse rate returns to normal.
Use a disposable needle only once. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
Wear a medical alert tag or carry an ID card stating that you have hemophilia. Any medical care provider who treats you should know that you have a bleeding or blood-clotting disorder.
If you need any type of surgery or dental work, tell the surgeon or dentist ahead of time that you have hemophilia.
You may need regular medical tests to be sure this medication is not causing harmful effects. Visit your doctor regularly.
Store the medication and the diluent in the refrigerator and do not allow them to freeze.
Throw away any unused medicine or diluent after the expiration date on the label has passed.
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Factor IX is sometimes used only when needed, so you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
Mechanism of Action
Mixture of vitamin K-dependent clotting factors; temporarily increases the plasma levels of Factor IX, thus minimizing the hazards of hemorrhage in patients with hemophilia B

Before Using Bebulin
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Blood clots may be especially likely to occur in premature and newborn babies, who are usually more sensitive than adults to the effects of injections of factor IX.
This medicine has been tested and has not been shown to cause different side effects or problems in older people than it does in younger adults.

Review Date: October 4, 2017
Bebulin (Factor IX Complex), Nanofiltered and Vapor Heated, is a purified, sterile, stable, freeze-dried concentrate of the Coagulation Factor IX (Christmas Factor) as well as Factor II (Prothrombin) and Factor X (Stuart Prower Factor) and low amounts of Factor VII. In addition, the product contains small amounts of heparin (≤ 0.15 IU heparin per IU Factor IX).
Bebulin is standardized in terms of Factor IX content and each vial is labeled for the Factor IX content indicated in International Units (IU). One International Unit of Factor IX (according to the current International Standard for Human Blood Coagulation Factors II, IX, and X in Concentrates) corresponds to the activity of Factor IX in 1 mL of fresh normal human plasma.
Bebulin is manufactured from large plasma pools of human plasma. Screening against potentially infectious agents begins with the donor selection process and continues throughout plasma collection and plasma preparation. Each individual plasma donation used in the manufacture of Bebulin is collected only at FDA approved blood establishments and is tested by FDA licensed serological tests for Hepatitis B Surface Antigen (HBsAg), and for antibodies to Human Immunodeficiency Virus (HIV-1/HIV-2) and Hepatitis C Virus (HCV) in accordance with U.S. regulatory requirements. As an additional safety measure, mini-pools of the plasma are tested for the presence of HIV-1 and HCV by FDA licensed Nucleic Acid Testing (NAT) and found negative. In addition, two dedicated and independent virus removal/inactivation steps have been integrated into the manufacturing process, namely 35 nm nanofiltration1 and a vapor heat treatment process2 [10 hours at 60°C and subsequent 1 hour at 80°C under the condition of 7-8% (w/v) residual moisture]. In addition, the DEAE-Sephadex adsorption contributes to the virus safety profile of Bebulin. Despite these measures, such products can still potentially transmit disease (see WARNINGS).
In vitro spiking studies have been used to validate the capability of the manufacturing process to remove and inactivate viruses. To establish virus clearance capacity of the manufacturing process, these virus clearance studies were performed in accordance with good laboratory practices under extreme conditions (e.g. at minimum incubation times and temperatures below specifications for vapor –heat treatment). The in vitro viral reduction studies performed on nanofiltered Bebulin are summarized in Table 1 .
| * Reduction factors < 1 log are not used for calculation of the overall reduction factor. † Studies on B19V, which are considered experimental in nature, have demonstrated a virus reduction factor of not more than 3.6 log10 and 4.6 log10 by DEAE-Sephadex adsorption and vapor -heat treatment, respectively. ‡ HIV-1, Human Immunodeficiency Virus Type 1 |
