1. Why am I using ALPROLIX?

ALPROLIX contains the active ingredient eftrenonacog alfa (recombinant coagulation factor IX fusion protein). ALPROLIX is used for the management of haemophilia B (congenital factor IX deficiency).

People with haemophilia B lack sufficient factor IX to control bleeding. ALPROLIX works by replacing factor IX to enable blood to clot.

ALPROLIX is used to

  • control and prevent bleeding episodes
  • routinely prevent and reduce the frequency of bleeding episodes
  • reduce bleeding before, during, and after surgery.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

This medicine helps to control your condition but does not cure it.

Your doctor may have prescribed it for another reason.

2. What should I know before I use ALPROLIX?


Do not use ALPROLIX if:

  • you are allergic to eftrenonacog alfa or other factor IX replacement factors, or any of the ingredients listed at the end of this leaflet.

Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • have any other medical conditions
  • take any medicines for any other condition

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

3. What if I am taking other medicines?
