    • What is this medication and its most common uses?

      Idelvion is a medicine used to control and prevent bleeding episodes in people with hemophilia B (also called congenital factory IX deficiency or Christmas disease). Idelvion is also used during surgery. Idelvion is administered intravenously (directly into your vein).

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Hemophilia B is a type of bleeding disorder that prevents blood from clotting normally. Idelvion works by replacing a clotting factor called factor IX, helping your blood to form clots and decreasing bleeding episodes.

      What are the beneficial effects of this medication and when should I begin to have results?

      What: Idelvion may reduce the number of bleeding episodes when used regularly.

      When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. It is important that you use Idelvion exactly as your healthcare provider has prescribed.

      How do I know it is working?

    • What are the possible side effects of this medication?

      The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.

      Increased risk of forming abnormal blood clots in your body, with symptoms such as chest pain, difficulty breathing, leg tenderness, or swelling.
