ADVATE contains the active substance octocog alfa, human coagulation factor VIII produced by recombinant DNA technology. Factor VIII is necessary for the blood to form clots and stop bleedings. In patients with haemophilia A (inborn factor VIII deficiency), it is missing or not working properly.
ADVATE is used in patients with haemophilia A for prevention or treatment of spontaneous or surgery-related bleeding.
ADVATE is prepared without the addition of any human- or animal-derived protein in the cell culture process, purification or final formulation.

Do not use ADVATE
- if you are allergic (hypersensitive) to octocog alfa or any of the other ingredients of ADVATE
- if you are allergic to mouse or hamster proteins If you are unsure about this, ask your doctor.
Take special care with ADVATE
You should tell your doctor if you have been previously treated with Factor VIII products, especially if you developed inhibitors, since there might be a higher risk that it happens again. Inhibitors are blocking antibodies against factor VIII that reduce the efficacy of ADVATE to prevent or control bleeding. Development of inhibitors is a known complication in the treatment of haemophilia A. If your bleeding is not controlled with ADVATE, tell your doctor immediately.
There is a rare chance that you may experience an anaphylactic reaction (a severe, sudden allergic reaction) to ADVATE. You should be aware of the early signs of allergic reactions such as rash, hives, wheals, generalised itching, swelling of lips and tongue, difficulty in breathing, wheezing, tightness in the chest, general feeling of being unwell, and dizziness. These symptoms can constitute an early
symptom of an anaphylactic shock, manifestations of which may additionally include extreme dizziness, loss of consciousness, and extreme difficulty in breathing.
If any of these symptoms occur, stop the injection immediately and contact your doctor. Severe symptoms, including difficulty in breathing and (near) fainting, require prompt emergency treatment.
Taking other medicines
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Pregnancy and breast-feeding
Tell your doctor if you are pregnant or breast-feeding.
Your doctor will decide if ADVATE may be used during pregnancy and breast-feeding.
Driving and using machines
ADVATE has no influence on your ability to drive or to use machines.
Important information about some of the ingredients of ADVATE
This medicinal product contains 0.45 mmol sodium (10 mg) per vial. To be taken into consideration by patients on a controlled sodium diet.
Treatment with ADVATE will be started by a doctor who is experienced in the care of patients with haemophilia A.
Your doctor will calculate your dose of ADVATE (in international units or IU) depending on your condition and body weight, and on whether it is used for prevention or treatment of bleeding. The frequency of administration will depend on how well ADVATE is working for you. Usually, the replacement therapy with ADVATE is a life-long treatment.
Prevention of bleeding
The usual dose of octocog alfa is 20 to 40 IU per kg body weight, administered every 2 to 3 days. However, in some cases, especially in younger patients, more frequent injections or higher doses may be necessary.
Treatment of bleeding
The dose of octocog alfa is calculated depending on you body weight and the factor VIII levels to be achieved. The target factor VIII levels will depend on the severity and location of the bleeding. Dose (IU) = body weight (kg) x desired Factor VIII rise (% of normal) x 0.5
If you have the impression that the effect of ADVATE is insufficient, talk to your doctor. Your doctor will perform appropriate laboratory tests to make sure that you have adequate Factor VIII levels. This is particularly important if you are having major surgery.
Patients developing Factor VIII inhibitors
If your plasma Factor VIII fails to reach expected levels with ADVATE, or if bleeding is not adequately controlled, it could be due to the development of Factor VIII inhibitors. This will be checked by your doctor. You might need a higher dose of ADVATE or even a different product to control bleedings. Do not increase the total dose of ADVATE to control your bleeding without consulting your doctor.
How ADVATE is given
ADVATE is usually injected into a vein (intravenously) by your doctor or nurse. You or someone else might also administer ADVATE as an injection, but only after receiving adequate training. Detailed instructions for self-administration are given at the end of this package leaflet.
If you use more ADVATE than you should
Always take ADVATE exactly as your doctor has told you. You should check with your doctor if you are not sure. If you inject more ADVATE than recommended, tell your doctor as soon as possible.
If you forget to use ADVATE
Do not inject a double dose to make up for a forgotten dose. Proceed with the next injection as scheduled and continue as advised by your doctor.
If you stop using ADVATE
Do not stop using ADVATE without consulting your doctor.
If you have any further questions on the use of this product, ask your doctor.
Like all medicines, ADVATE can cause side effects, although not everybody gets them.
If severe, sudden allergic reactions (anaphylactic) occur, the injection must be stopped immediately. You must contact your doctor immediately if you have any of the following early symptoms of allergic (hypersensitivity) reactions:
- rash, hives, wheals, generalised itching,
- swelling of lips and tongue,
- difficulty in breathing, wheezing, tightness in the chest,
- general feeling of being unwell,

INSTRUCTIONS FOR PREPARATION AND ADMINISTRATION
Aseptic technique is required during preparation of the solution and administration.
Use only the sterilised water for injections and the reconstitution device for preparation of the solution that are provided with each package of ADVATE. ADVATE must not be mixed with other medicinal products or solvents.
Instructions for reconstitution Do not use after the expiry date stated on the labels and carton. Do not use if the BAXJECT II device, its sterile barrier system or its packaging is damaged or shows any sign of deterioration as indicated by the symbol . Do not refrigerate the solution after preparation.
1. If the product is still stored in a refrigerator, take both the ADVATE powder and solvent vials from the refrigerator and let them reach room temperature (between 15°C and 25°C).
2. Wash your hands thoroughly using soap and warm water.
3. Remove caps from powder and solvent vials.
4. Cleanse stoppers with alcohol swabs. Place the vials on a flat clean surface.
5. Open the package of BAXJECT II device by peeling away the paper lid without touching the inside (Fig. a). Do not remove the device from the package. Do not use if the BAXJECT II device, its sterile barrier system or its packaging is damaged or shows any sign of deterioration.
6. Turn the package over and insert the clear plastic spike through the solvent stopper. Grip the package at its edge and pull the package off BAXJECT II (Fig. b). Do not remove the blue cap from the BAXJECT II device.
7. For reconstitution only the water for injections and the reconstitution device provided in the pack should be used. With BAXJECT II attached to the solvent vial, invert the system so that the solvent vial is on top of the device. Insert the white plastic spike through the ADVATE stopper. The vacuum will draw the solvent into the ADVATE vial (Fig. c).
8. Swirl gently until all material is dissolved. Be sure that ADVATE is completely dissolved, otherwise not all reconstituted solution will pass through the device filter. The product dissolves rapidly (usually in less than 1 minute). After reconstitution the solution should be clear, colourless and free from foreign particles.
