What Prothrombinex®-VF is used for
Prothrombinex®-VF contains the concentrated human coagulation factors II, IX and X and low levels of the factors V and VII. These are proteins which are essential for the normal blood clotting process. The coagulation factors II, VII, IX and X which are synthesised in the liver with the help of vitamin K, are commonly called the prothrombin complex. Individuals with coagulation factor levels lower than normal exhibit signs of difficulty in forming blood clots, with these clots often taking longer to be made than normal. Sometimes the individual may bleed unexpectedly into their joints, muscles or internal organs.
Prothrombinex®-VF is used in patients who require reversal of anticoagulant therapy and for the prevention and treatment of bleeding in patients with low levels of factor II, IX or X. It is not recommended for the management of patients with isolated factor V or factor VII deficiency.
Ask your doctor if you have any questions about why Prothrombinex®-VF has been prescribed for you.

About blood products
This product is made from human blood. When products are made from human blood and injected into you, it is possible that viruses or other substances could be present in the product and cause an illness. These could be viruses such as hepatitis, human immunodeficiency virus (HIV), or human parvovirus B19 and theoretically the Creutzfeldt-Jakob Disease (CJD) agent. There could also be other infectious agents some of which may not yet have been discovered.
To reduce the risk of this happening extra steps are taken when manufacturing this product. Strict controls are applied when selecting blood donors and donations. The product is specially treated to remove and kill viruses. These special treatments are considered effective against certain viruses known as enveloped viruses (such as HIV and hepatitis B and C) and also non-enveloped viruses, such as hepatitis A. These procedures may have some effect against the non-enveloped virus, parvovirus B19. Despite these measures, the risk of viral and other agents’ infectivity cannot be totally eliminated.
Vaccines are available against some of these viruses and your doctor will be able to help you decide whether it is worthwhile having any of those vaccines.
Please discuss the risks and benefits of this medicine with your doctor.
How to use Prothrombinex®-VF
The dosage and administration of Prothrombinex®-VF must be carefully controlled. Your doctor will be responsible for determining what dose is appropriate to your condition. How much Prothrombinex®-VF you need and how long the therapy lasts will depend on your situation.
Prothrombinex®-VF will usually be given in a hospital. Should your doctor decide that treatment at home is appropriate, they will provide detailed instructions on how to use Prothrombinex®-VF.
Along with their intended effects, medicines may cause some unwanted effects, which can sometimes be serious. Furthermore, individual patients may react differently to the same dose of the same medicine. This applies to Prothrombinex®-VF.
Although severe reactions after Prothrombinex®-VF injection are rare, heart attacks and blood clots (thromboses) have occurred during treatment with Prothrombinex®-VF. Ask your doctor if you need more information.
If you experience any of the following side effects during the administration of Prothrombinex®-VF, tell your doctor immediately:
- dizziness, nausea or vomiting
- tightness of the chest
- wheezing or breathlessness.
Other possible unwanted effects include inflammation of veins, headache, pain and drowsiness. Lowering of blood platelets (thrombocytopenia) may sometimes occur due to a constituent in the formulation (heparin sodium).
Overdosage may enhance the risk of heart attacks and blood clots (thrombosis). If you have questions, consult your doctor.
