Important Safety Information and Indication
INDICATION
IMPORTANT SAFETY INFORMATION
INDICATION
ALPROLIX® [Coagulation Factor IX (Recombinant), Fc Fusion Protein] is an injectable medicine that is used to help control and prevent bleeding in people with hemophilia B. Hemophilia B is also called congenital Factor IX deficiency. Your healthcare provider may give you ALPROLIX when you have surgery.
IMPORTANT SAFETY INFORMATION
Do not use ALPROLIX if you are allergic to ALPROLIX or any of the other ingredients in ALPROLIX.

Tell your healthcare provider if you have or have had any medical problems, take any medicines, including prescription and non-prescription medicines, supplements, or herbal medicines, have any allergies and all your medical conditions, including if you are pregnant or planning to become pregnant, are breastfeeding, or have been told you have inhibitors (antibodies) to Factor IX.

Common side effects of ALPROLIX include headache, abnormal sensation in the mouth, and pain in your side with blood in your urine, which may be a sign of clot formation in the urinary collecting system.

Allergic reactions may occur with ALPROLIX. Call your healthcare provider or get emergency treatment right away if you have any of the following symptoms: hives, chest tightness, wheezing, difficulty breathing, or swelling of the face.

Redness to the skin at the injection site may also occur.

ALPROLIX may increase the risk of formation of abnormal blood clots in your body, especially if you have risk factors for developing blood clots. Call your healthcare provider or seek emergency care if you have symptoms of a possible abnormal blood clot, which may include: chest pain, difficulty breathing, unexpected swelling of an arm or leg with or without pain or tenderness.

Your body can also make antibodies called "inhibitors" against ALPROLIX, which may stop ALPROLIX from working properly.

These are not all of the possible side effects of ALPROLIX. Talk to your healthcare provider right away about any side effect that bothers you or does not go away, or if bleeding is not controlled using ALPROLIX.
