Factor IX is a protein naturally produced in the body which helps your blood to clot.
A lack of factor IX can cause uncontrolled bleeding, as the blood is unable to clot properly. Factor IX complex is used to help prevent or control bleeding problems to those who have a condition called haemophilia B (a disorder characterised by a low level of factor IX in the body).
Factor IX complex may be used to treat other conditions as decided by your doctor.
Factor IX complex is to be given intravenously (into the vein) via a drip. It is delivered directly into the bloodstream via the blood vessel.
Your doctor or nurse will administer this medicine for you.
The dose of Factor IX complex will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on the severity of your condition.
Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Factor IX complex.
If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.
