What Thrombotrol®-VF is used for
This medicine is used to prevent blood clots in people who have an inherited deficiency of antithrombin III in the following circumstances:
- before surgery
- during pregnancy
- during childbirth.
It can also be used to treat blood clots in these patients.
This medicine belongs to a group of medicines called antithrombotic agents. It works by increasing antithrombin III levels and thereby preventing the formation of blood clots.
Some people have an inherited deficiency of antithrombin III and these people may be at risk of spontaneous thrombosis (blood clots) or pulmonary embolism (blood clot which stops blood circulating through the lungs). The risk of these conditions increases with age and in association with surgery, pregnancy and childbirth.
Thrombotrol®-VF contains a concentrated form of antithrombin III which is a protein normally present in the blood and prevents the formation of blood clots.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

About blood products
Thrombotrol® VF is manufactured from human plasma (the liquid component of blood) collected by Australian Red Cross Lifeblood. When products are made from human blood, it is possible that viruses or other substances could be present in the product and cause an illness. These could include different types of viral hepatitis, human immunodeficiency virus (HIV), or parvovirus B19 and theoretically the Creutzfeldt-Jakob Disease (CJD) agent. There could also be other infectious agents which may have not yet been discovered.
To reduce the risk of this happening precautions 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 certain viruses. This special treatment is considered effective against viruses known as enveloped viruses (such as HIV, hepatitis B and C) and the non-enveloped virus, hepatitis A. Effectiveness against the non-enveloped virus parvovirus B19 may be limited.
Despite these measures, the risk of contamination with viruses or other agents cannot be completely 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.
Note: The safety and effectiveness of Thrombotrol®-VF in children and elderly has not been established.

Other medicines may be affected by Thrombotrol®-VF or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor has more information on medicines to be careful with or avoid while taking this medicine.
