General information about the safe and effective use of Ixinity
Your body may form inhibitors to factor IX. An inhibitor is part of the body’s immune system. If you form inhibitors, it may stop Ixinity from working properly. Consult with your healthcare provider to make sure you are carefully monitored with blood tests to check for the development of inhibitors to factor IX. Consult your doctor promptly if bleeding is not controlled with Ixinity as expected.
Medicines are sometimes prescribed for purposes other than those listed here. Do not use Ixinity for a condition for which it is not prescribed. Do not share Ixinity with other people, even if they have the same symptoms as you.
