What OBIZUR is used for
OBIZUR is a recombinant DNA derived, anti-haemophilic factor used for the treatment of bleeding episodes in adults with acquired haemophilia A.
It is possible that your doctor may give you OBIZUR for another reason.
Ask your doctor if you have any questions about why you are being given OBIZUR.
How does OBIZUR work
Under normal physiological conditions, factor VIII is essential for blood clotting and therefore the control of bleeding.
Acquired haemophilia is a bleeding disorder that is not present a birth but develops suddenly at some point in life due to an abnormality in the immune system. In patients with acquired haemophilia A, factor VIII is not working properly because the patient has developed antibodies which neutralise this blood clotting factor, and this prevents blood from clotting.
OBIZUR belongs to a group of medicines called anti-haemophilic agents.
OBIZUR is a man-made clotting factor. It is similar to the naturally occurring protein in the body.
OBIZUR works by temporarily replacing the inhibited human clotting factor VIII, so that blood can clot normally.

How OBIZUR is given
How much is given
Your doctor will decide the dose of OBIZUR you will receive. Each individual will receive a different amount, which may vary between treatments.
The dose you receive will be based on:
- body weight;
- your condition, e.g. in which sites the bleeding occurs (knees, muscle, etc.).
As a general guide, an initial first dose of 200 U per kilogram (U/kg) bodyweight is recommended.
The frequency and duration of treatment will depend on how well OBIZUR is working for you. Your doctor will adjust the dose and frequency of OBIZUR injections until the bleeding stopped.
How OBIZUR is given
OBIZUR is usually given in a hospital so that you are under the care of a healthcare professional.
OBIZUR is given by a slow injection directly into your vein.
Use aseptic technique to prepare OBIZUR for injection.
Use only the water for injections supplied with the pack to prepare OBIZUR for injection.
Do not mix OBIZUR with any other medicines or solvent.
Always inspect the solution after it is prepared for use and before injection. The solution should be clear and colourless.

Use the solution straight away or within 3 hours after it is prepared.
Do not refrigerate the solution after it is prepared.
Use a new syringe and needle for each injection.
Do not mix OBIZUR with other medicines.
If you are given too much (overdose)
As OBIZUR will be given to you by a doctor/nurse, it is unlikely that you will be given an overdose.
Your healthcare professional will regularly monitor your condition and test your blood to prevent overdose.
Immediately telephone your doctor or the National Poisons Information (telephone 131 126), or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have been given too much OBIZUR.
Do this even if there are no signs of discomfort or poisoning.
While you are using OBIZUR
Things you must do
You will have your blood tested after the initial OBIZUR injection and also regularly after subsequent injections to see how your treatment is working. This is to check the your blood level of factor VIII to confirm that you have received adequate treatment. Your doctor will also check if the bleeding is adequately controlled.
Your doctor may do additional blood tests to check if you have developed antibodies to OBIZUR treatment.
Monitor your bleeding and tell your doctor or nurse if your bleeding gets worse.
Tell your doctor or pharmacist immediately if you experience any of the following during the OBIZUR injection:
- shortness of breath; wheezing; difficulty breathing; chest pain or discomfort;
- changes in facial skin colour, puffiness or swelling of your face, lips, tongue, or other parts of the body, rash or hives.
