1. WHAT REPLENINE-VF IS AND WHAT IT IS USED FOR
Replenine-VF is a high purity factor IX from human blood plasma obtained from screened donors. It is a white sterile powder, supplied with sterile water (Water for Injections).
Replenine-VF is given by injection into a vein (intravenously) and is used to prevent and treat bleeding in patients with haemophilia B (an inherited shortage of factor IX in the blood). Your doctor will explain further why this medicine has been given to you.
2. BEFORE YOU USE REPLENINE-VF 1 2
Always use this medicine exactly as your doctor has told you to. You should check with your doctor if you are not sure.
Adults
Replenine-VF should be administered directly into a vein. Use only the recommended injection equipment.
• Your doctor will explain how much you should use.
• The dose, especially the first dose, should be given slowly (approximately 3 mL per minute).
• After reconstitution, the injection should be completed within one hour and the solution must not be stored.
• If further treatment is needed, doses may be repeated at intervals of 8 to 24 hours, as required. Your doctor will advise you if this is necessary.
The table gives the approximate doses of factor IX which are needed to stop bleeding in various conditions:
|
Condition |
Initial dose of Replenine-VF (IU/kg body weight) |
|
Minor spontaneous bleeding in joints and muscles. |
17 to 34 |
|
Severe bleeding in joints and muscles, bruising, minor surgery, e.g. tooth extraction, cartilage repair. |
25 to 51 |
|
Life-threatening bleeding, majorsurgery.2 |
51 to 85 |
• In majorsurgery Replenine-VF may be given either as individual injections or by continuous infusion over several days (see also section: How much is given before, during and after major surgery?).
Children under 6 years of age
Your doctor will recommend the appropriate dose for young children. Generally the calculation of doses for children should follow that for adults.
When to inject Replenine-VF
• The medicine should be injected when the first sign of bleeding occurs.
• The injection should be repeated as necessary to stop the bleeding.
• Each individual bleed should be judged on its own severity.
• Replenine-VF can also be injected as part of treatment to prevent bleeding starting.
• If you are using this product for the first time, your doctor will supervise you.
Dissolving your medicine before use
|
Vial of Replenine-VF |
Quantity of Water |
|
250 IU |
2.5 or 5 mL |
|
500 IU |
5 or 10 mL |
|
1000 IU |
10 or 20 mL |
1) Replenine-VF must only be dissolved in the sterile water provided with the product.
2) Before you remove its “flip-off” top, make sure that the vial of Replenine-VF and the container of water supplied with it are both at room temperature (between 20°C and 30°C).
3) Remove the cap from the Replenine-VF vial.
4) Clean the top of the medicine stopper with a spirit swab.
5) Sterile water for use with Replenine-VF is provided in two different types of container:
• a plastic ampoule. Break open the top and draw up the required volume of water with a needle and syringe (not the single point filter needle with the connection for a syringe).
• a glass vial with a stopper.
- pierce the stopper with a needle and syringe and draw up the required volume of water, or
- if the glass vial is labelled with the precise volume of water you require, insert one end of a double-spiked needle (which your doctor will provide) through the stopper into the water then invert the water vial and needle and insert the other end of this double needle into the product container.
6) Once you have pierced the Replenine-VF vial with the needle and syringe filled with water (or the double-ended needle attached to the water vial) water will flow into the container.
7) As the water enters the vial, swirl the vial gently around to wet the powder, but do not shake it.
8) Do not use this medicine if:
- the water is not pulled into the vial (this indicates a loss of vacuum in the vial, so the powder must not be used).
- the dissolved powder and sterile water form a gel or a clot (if this happens, please tell Bio Products Laboratory, reporting the batch number printed on the vial).
9) Remove the syringe or empty water container from the needle before removing the needle from the medicine vial.
10) Continue swirling the vial around gently until the powder is completely dissolved. A clear or slightly pearl-like solution should be obtained, usually in about 2 to 2Vi minutes (5 minutes maximum).
11) If you have to use more than one vial to make up your dose, you need to draw up the solution in each vial into one syringe for your injection, but you must use a new sterile filter needle to draw the contents of each vial up into the plastic syringe.
12) Do not use solutions which are cloudy or have bits in them.
Injecting the medicine
After the medicine is dissolved:
• Clean the stopper again, with a spirit swab.
• Draw the medicine into a plastic, disposable syringe through the sterile filter needle provided (this will remove any tiny particles).
• To inject the medicine, attach a suitable needle or “butterfly” to the syringe.
• The dose, especially the first dose, should be given slowly (no more than 3mL per minute) into your vein.
Remember:
- the solution must not be stored after reconstitution.
- you must finish injecting the dose into a vein within one hour of dissolving the medicine.
- the solution must not be added to any other fluids, blood or any other medicine.
- you should only use the sterile Water for Injections to make up the solution, but you must never inject the water on its own, without the powder.
How much is given before, during and after major surgery?
(See also the table on page 2.)
Before: Major surgery should only be performed when levels of factor IX and factor IX inhibitors (antibodies) in your blood can be tested. If antibodies are not present, a dose is given before the operation to increase the level in your blood to between 80 and 100 IU/dL, usually about 65-85 IU per kg of body weight.
After: During the first few days after the operation, the plasma factor IX concentration will be checked at regular periods. A dose of Replenine-VF (factor IX) is usually given every 8-24 hours, as needed.
After the first few days, the number of doses may be reduced.
Treatment is usually continued for 7 days or longer, depending on the type of operation.
If the factor IX concentration does not reach the expected level (this will be tested by your doctor), or if it decreases faster than expected (within 12 hours), an inhibitor of factor IX may be present which stops it from working properly. Your doctor will arrange for the appropriate laboratory tests to see if there is such an inhibitor present.
If you use more Replenine-VF than you should
If you think you may be using too much, stop the injection and tell your doctor.
If you know you have used too much, tell your doctor as soon as possible.
If you forget to use Replenine-VF
Do not use a double dose to make up for a forgotten dose.
If you stop using Replenine-VF
Always consult your doctor before deciding to stop your treatment.

Please note
When medicines are made from human blood or plasma, certain measures are put in place to prevent infections being passed on to patients. These include careful selection of blood and plasma donors to make sure those at risk of carrying infections are excluded, and the testing of each donation and pools of plasma for signs of virus/infections. Manufacturers of these products also include steps in the processing of the blood or plasma that can inactivate or remove viruses. Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of passing on infection cannot be totally excluded. This also applies to any unknown or emerging viruses or other types of infection.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus and for the non-enveloped hepatitis A and parvovirus B19 viruses.
It is strongly recommended that every time you recieve a dose of Replenine-VF the name and batch number of the product are recorded in order to maintain a record of the batches used.
As with all medicines, Replenine-VF may cause side effects, although not everybody gets them.
Hypersensitivity or allergic reactions have been observed infrequently in patients treated with factor IX containing products. If you get any of the following symptoms, stop the infusion and tell your doctor immediately:
• swelling around the face and throat
• burning and stinging at the infusion site
• chills
• flushing
• nettle-rash (urticaria)
• headache
hives
Kidney problems (such as nephrotic syndrome) have been reported in some haemophilia B patients who have inhibitors (antibodies) to factor IX and a history of allergic reaction to factor IX containing products.
Inhibitors (antibodies) may develop to factor IX during treatment. This could mean that the treatment does not work properly. If bleeding does not stop after an injection, then speak to your doctor.
On rare occasions, fever has been observed (in fewer than 1 in 1,000 people).
The use of low purity factor IX products has been associated with heart attack, thrombosis and blood coagulation. The use of high purity factor IX, such as Replenine-VF, is rarely associated with such side effects.
In clinical trials with Replenine-VF, the following side effects have been reported in fewer than 1 in 10 people:.
• Reaction at the injection site, e.g. irritation, inflammation, suddenly have unusual bruising and feeling very unwell.
• Headache.
If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your doctor.
