6. Contents of the pack and other information
1. what coagadex is and what it is used for
Coagadex is a concentrate of human coagulation factor X, a protein that is needed for blood to clot. The factor X in Coagadex is extracted from human plasma (the liquid part of blood). It is used to treat and prevent bleeding in patients with hereditary factor X deficiency, including during surgery.
Patients with factor X deficiency do not have sufficient factor X for their blood to clot properly, leading to excessive bleeding. Coagadex replaces the missing factor X and allows their blood to clot normally.
2. what you need to know before you use coagadex
Do not use Coagadex:
-
– if you are allergic to human coagulation factor X or any of the other ingredients of this medicine (listed in section 6).
Check with your doctor if you think this applies to you.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using Coagadex:
-
– if you have a larger or longer bleed than usual and the bleeding does not stop after an injection of Coagadex.
Some patients with a shortage of factor X may develop inhibitors (antibodies) to factor X during treatment. This could mean that the treatment will not work properly. Your doctor will check regularly for the development of these antibodies, and especially before an operation. Both before and after treatment with this medicine, particularly for your first course of treatment, your doctor will probably carry out tests to check the level of factor X in your blood.
Virus safety
When medicines are made from human blood or plasma, certain measures are put in place to prevent infections being passed on to recipients. These include:
-
– careful selection of blood and plasma donors to make sure those at risk of carrying infections are excluded,
-
– the testing of each donation and pools of plasma for signs of virus/infections,
-
– the inclusion of steps in the processing of the blood or plasma that can inactivate or remove viruses.
The measures taken are considered effective for the following viruses: human immunodeficiency virus (HIV), hepatitis B virus, hepatitis C virus, hepatitis A virus and parvovirus B19. Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of passing on an infection cannot be totally excluded. This also applies to any unknown or emerging viruses or other types of infections.
It is strongly recommended that every time you receive a dose of Coagadex, the name and 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 you regularly or repeatedly receive human plasma-derived factor X products.
Children and adolescents
The listed warnings and precautions for adults also apply to children (aged 2 to 11 years) and adolescents (aged 12 to 18 years).
Other medicines and Coagadex
Tell your doctor if you are taking, have recently taken or might take any other medicines. Certain anticoagulants including those blocking a blood clotting factor (factor Xa) should not be used in patients with factor X deficiency receiving Coagadex due to a risk of blood clots.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Driving and using machines
There are no known effects of this medicine on the ability to drive or operate machinery.
Coagadex contains sodium
This medicinal product contains up to 0.4 mmol/mL (9.2 mg/mL) of sodium. This should be taken into consideration by patients on a controlled sodium diet.
3. how to use coagadex
Your treatment should be initiated by a doctor who is experienced in the treatment of bleeding disorders.
Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
Coagadex should be injected directly into a vein. Before injecting this medicine at home, you should have received training by your healthcare professional on how to do so.
Your doctor will explain to you how much you should use, when you should use it and for how long. Your doctor will usually tell you your dose in terms of the number of full vials that supply the dose most suited to you. Not more than 60 IU/kg daily should be administered in any age group.
Adult
How much Coagadex is given to treat a bleed or prevent further bleeding?
Your doctor will tell you how much Coagadex to administer to treat a bleed and to prevent further bleeding; the dose required will depend on your normal blood level of factor X.
How much is given before, during and after major surgery?
Before: The dose of Coagadex used should be sufficient to raise your blood factor X level to between 70 and 90 units/dL. The dose you need will depend on your normal blood level of factor X and will be calculated by your doctor.
After: During the first few days after the operation, your plasma factor X concentration will be checked regularly. It is recommended that your blood factor X level is kept above 50 units/dL. The dose you need will be calculated by your doctor.
If your blood factor X concentration is too low (this will be tested by your doctor), or if it decreases faster than expected, an inhibitor to factor X may be present which stops Coagadex from working properly. Your doctor will arrange for the appropriate laboratory tests to see if this is the case.
How much is given regularly for long-term prevention of bleeds?
Your doctor will advise if this use is suitable for you and, if so, of the appropriate dose.
Use in children and adolescents
Your doctor will recommend an appropriate dose for you. Generally the doses for children less than 12 years old are larger than doses for adolescents which should follow those in adults.
When to inject Coagadex
- 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
- If you are using this medicine for the first time, your doctor will supervise you
