Proplex-T Patient Information Including Side Effects

Brand Names: Bebulin VH, Konyne 80, Profilnine SD, Proplex T

Generic Name: factor IX complex (Pronunciation: FAK tor NINE KOM plex)

What is factor IX complex (Proplex-T)?

Factor IX (nine) is a naturally occurring protein in the blood that helps blood to clot. A lack of clotting factors can cause uncontrolled bleeding, as the blood is unable to clot properly.

Factor IX complex is a combination of four different clotting factors and other proteins. This medication works by temporarily raising levels of these clotting factors in the blood to aid in clotting.

Factor IX complex is used to treat or prevent bleeding episodes in people with hemophilia B. It is also used to control bleeding related to surgery or dentistry in people with hemophilia B.

Factor IX may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about factor IX complex (Proplex-T)?

Before using factor IX complex, your specific blood clotting disorder must be diagnosed as factor IX or factor VIII (eight) deficiency.

Your doctor may want you to receive a hepatitis vaccination before you start using factor IX complex.

Use this medication exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Follow the instructions on your prescription label. Always check the strength of the medicine on the label to be sure you are using the correct potency.

Carry an ID card or wear a medical alert bracelet stating that you have hemophilia in case of emergency. Any doctor, dentist, or emergency medical care provider who treats you should know that you have a bleeding or blood-clotting disorder.

Factor IX complex is made from human plasma (part of the blood) and may contain viruses and other infectious agents that can cause disease. Although donated human plasma is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.
