6.    Further information

Wilate belongs to the pharmacotherapeutic group of medicines called clotting factors and contains human blood coagulation factor VIII (FVIII) and von Willebrand factor (VWF). Together these two proteins are involved in blood clotting.

Von Willebrand disease

Wilate is used to treat and prevent bleeding in patients with von Willebrand disease (VWD), which in fact is a family of related diseases. All types of VWD are inborn, where bleeding can go on for longer than expected. This is either due to a lack of VWF in the blood or due to VWF that does not work the way it should.

Haemophilia A

Wilate is used to treat and prevent bleeding in patients with haemophilia A. This is a condition in which bleeding can go on for longer than expected. It is due to an inborn lack of FVIII in the blood.

Do not use Wilate

•    if you are allergic (hypersensitive) to human blood coagulation factor VIII, von Willebrand factor or any of the other ingredients of Wilate.

Take special care with Wilate

•    Any medicine, such as Wilate, which is prepared from human blood (containing proteins) and which is injected into a vein (administered intravenously) can cause allergic reactions. Please pay attention to early signs of allergic reactions (hypersensitivity), such as hives, skin rash, tightness of the chest, wheezing, low blood pressure, or anaphylaxis (when any or all of the above symptoms develop rapidly and are intense)

If these symptoms occur, stop the injection immediately and contact your doctor.

•    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 infections.

The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B (HBV) virus and hepatitis C virus (HCV), and for the non-enveloped hepatitis A virus (HAV). The measures taken may be of limited value against non-enveloped viruses such as parvovirus B19.

Parvovirus B19 infection may be serious for pregnant women (infection of the baby) and for individuals whose immune system is depressed or who have some types of anaemia (e.g. sickle cell disease or abnormal breakdown of red blood cells).

•    It is strongly recommended that every time you receive a dose of Wilate the name and the batch number of the product are recorded in order to maintain a record of the batches used.

Your doctor may recommend that you consider vaccination against hepatitis A and B if your regularly/repeatedly receive human plasma-derived FVIII/VWF products.

Von Willebrand disease (VWD)

•    Please see section 4. (Von Willebrand disease (VWD)) for side effects related to the treatment of VWD.

Haemophilia A

•    Please see section 4. (Haemophilia A) for side effects related to the treatment of haemophilia A.

Taking other medicines

Although no influences on Wilate from other medicinal products are known, please tell your doctor or pharmacist if you are taking or have recently taken any other medicines (including medicines obtained without a prescription).

Please do not mix Wilate with any other medicines during the injection.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before using Wilate.

Important information about some of the ingredients of Wilate

This medicinal product contains up to 2.55 mmol sodium (58.7 mg) per dose for 500 IU FVIII and VWF/vial and up to 5.1 mmol sodium (117.3 mg) per dose for 1000 IU FVIII and VWF/vial. To be taken into consideration if you are on a controlled sodium diet.

Wilate should be injected into a vein (administered intravenously) after reconstitution with the supplied solvent. Treatment should be started under medical control.

Dosage

Your doctor will advise you about your individual dosage and the frequency with which you should use Wilate. Always use Wilate exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

If you use more Wilate than you should

No symptoms of overdose with human FVIII or VWF have been reported. However, the recommended dosage should not be exceeded.

If you forget to take Wilate

Do not take a double dosage to make up for a forgotten dosage.

If you have any further questions on the use of this product, ask your doctor or pharmacist.

Like all medicines, Wilate can cause side effects, although not everybody gets them.

•    Even though uncommon, hypersensitivity or allergic reactions have been observed. These may include:

burning and stinging at the infusion site, chills, flushing, headache, hives (uticaria), low blood pressure (hypotension), tiredness (lethargy), sickness (nausea), restlessness, increase of heart rate (tachycardia), tightness of the chest, feeling of pins and needles (tingling), vomiting, wheezing, sudden swellings in various parts of the body (angiooedema).

If you suffer from any of the above-mentioned symptoms, please inform your doctor.

You should stop using Wilate and see your doctor immediately, if you experience symptoms of angiooedema, such as:

o swollen face, tongue or throat (pharynx)

o difficulties to swallow

o hives and difficulties to breath

•    On rare occasions, fever has been observed.

•    In very rare cases, hypersensitivity may lead to a severe allergic reaction called anaphylaxis (when any or all of the above symptoms develop rapidly and are intense), which may include shock. In case of an anaphylactic shock, treatment using the current medical recommendations for shock is essential.

Von Willebrand disease (VWD)

•    When using a FVIII-containing VWF product to treat VWD, the continued treatment may cause an excessive rise in FVIII in the blood. This may increase the risk that your blood flow will be disturbed (thrombosis).

If you are a patient with known clinical or laboratory risk factors, you have to be checked for early signs of thrombosis. Prevention (prophylaxis) of thrombotic events should be decided by your doctor, according to the current recommendations.

•    Patients with VWD (especially type 3 patients) may develop inhibitors (neutralising antibodies) to VWF during the treatment with VWF. In these very rare cases inhibitors can stop Wilate working properly.

In case your bleeding continues, your blood has to be tested for these inhibitors.

Inhibitors may increase the risk of suffering severe allergic reactions (anaphylactic shock). If you suffer an allergic reaction, you should be tested for the presence of inhibitors.

Once inhibitors have been found in your blood, please contact a physician with experience in the care of patients with bleeding disorders. In patients with high amounts of inhibitors, another kind of treatment might be useful and should be considered.

Haemophilia A

•    When using FVIII products to treat patients with haemophilia A, the formation of inhibitors (neutralising antibodies) to FVIII is a known complication. In these rare cases inhibitors can stop Wilate working properly and bleeding may continue. Please contact a specialised haemophilia centre if Wilate does not stop your bleeding. Regular blood tests will be performed during treatment to test for these inhibitors.

Inhibitors may increase the risk of suffering severe allergic reactions (anaphylactic shock). If you suffer an allergic reaction, you should be tested for the presence of inhibitors.
