Contents of the pack
What is Beriplex
Beriplex is presented as a powder and solvent. It is a white or slightly colored powder or friable solid. The prepared solution should be administered by injection into a vein.
Beriplex is prepared from human plasma (the liquid part of the blood) and contains human coagulation factors II, VII, IX, and X. Concentrates containing these coagulation factors are called prothrombin complex products. Coagulation factors II, VII, IX, and X are vitamin K-dependent and are important for blood coagulation. The lack of any of these factors means that the blood does not clot as quickly as it should, and there is an increased tendency to bleed. Replacement of factors II, VII, IX, and X with Beriplex repairs the coagulation mechanisms.
What is Beriplex used for
Beriplex is used for the prophylaxis (during surgery) and treatment of bleeding caused by acquired or congenital deficiency of vitamin K-dependent coagulation factors, i.e., factors II, VII, IX, and X in the blood, when specific coagulation factor products are not available.
The following sections contain information that your doctor should consider before administering Beriplex to you.
Do not use Beriplex
Tell your doctor if you are allergic to any medicine or food.
Tell your doctor or pharmacist if you have any of these diseases.
Warnings and precautions
Consult your doctor or pharmacist before starting to use Beriplex if:
In these cases, the effect of heparin may be reduced (heparin tolerance). If such symptoms occur, you should stop using the product immediately and inform your doctor. In the future, you should not use products containing heparin.
Your doctor will carefully weigh the benefits of treatment with Beriplex against the risk of these complications.
Viral safety
When medicines are prepared from human blood or plasma, certain measures are taken to prevent the transmission of infections to patients. These measures include:
Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of transmitting an infection cannot be completely excluded. This also applies to 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 virus, and hepatitis C virus, and for the non-enveloped hepatitis A virus and parvovirus B19.
It is possible that your doctor may recommend vaccination against hepatitis A and B if you are treated regularly/repeatedly with prothrombin complex products derived from human plasma.
It is strongly recommended that each time you are administered a dose of Beriplex, the name and batch number of the medicine should be recorded, in order to maintain a record of the batches used.
Using Beriplex with other medicines
Pregnancy, breastfeeding, and fertility
Driving and using machines
No studies have been performed on the ability to drive or use machinery.
Beriplex contains sodium
Patients on low-sodium diets should be aware that this medicine contains up to 343 mg of sodium (approximately 15 mmol) per 100 ml. This should be taken into consideration by patients on a controlled sodium diet.
Treatment should be initiated and supervised by a doctor experienced in the treatment of this type of disorder.
Posology
The amount of Factor II, VII, IX, and X you need and the duration of treatment will depend on various factors, such as your body weight, the severity and nature of your disease, the location and severity of the bleeding, or the need to prevent bleeding during surgery or investigation (see the section "This information is intended only for healthcare professionals").
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Overdose
Your doctor will regularly check your blood coagulation status during treatment. High doses of prothrombin complex concentrate have been associated with heart attacks, disseminated intravascular coagulation, and increased blood clot formation in blood vessels in patients at risk of these complications.

Posology and Method of Administration
Posology
The following dosage guidelines are of a general nature only.
The dosage and frequency of administration will be established individually for each patient. The dosing intervals must be adapted to the circulating half-lives of the respective coagulation factors of the prothrombin complex. Individual dosage requirements can only be identified based on periodic determination of plasma levels of the relevant coagulation factors or analysis of the overall levels of the prothrombin complex (INR, Quick test) and continuous monitoring of the patient's clinical situation.
In the case of major surgical interventions, precise monitoring of substitution therapy is essential, by means of coagulation analysis (specific factor assays and/or global tests to measure prothrombin complex levels).
The dosage will depend on the INR value before treatment and the INR value to be achieved. The INR value before treatment should be taken as close as possible to the time of administration to calculate the adequate dose of Beriplex. The following table provides approximate doses (ml of reconstituted product solution/kg of body weight and IU of factor IX/kg of body weight) required to normalize the INR (e.g., < 1.3) at different initial INR levels.
INR before treatment | 2.0 – 3.9 | 4.0 – 6.0 | > 6.0 |
Approximate dose (ml/kg of body weight) | 1 | 1.4 | 2 |
Approximate dose of factor IX (IU)/kg of body weight | 25 | 35 | 50 |
The dose is based on body weight up to, but not exceeding, 100 kg. For patients whose body mass exceeds 100 kg, the maximum single dose (IU of factor IX) must not exceed 2,500 IU for an INR of 2.0 – 3.9, 3,500 IU for an INR of 4.0 – 6.0, and 5,000 IU for an INR > 6.0.
Correction of the hemostasis disorder induced by vitamin K antagonists is commonly achieved approximately 30 minutes after injection. Simultaneous administration of vitamin K should be considered in patients treated with Beriplex for the urgent neutralization of vitamin K antagonists, as the effect of vitamin K is normally achieved after 4 to 6 hours. Repeated administration of Beriplex is not recommended in patients who require urgent treatment for neutralization of vitamin K antagonists, as it is not supported by clinical data.
These recommendations are based on data from clinical trials with a limited number of individuals. Recovery and duration of effect may vary, so monitoring of INR during treatment is mandatory.
The calculation of the required dose of prothrombin complex concentrate is based on clinical trial data:
?1 IU of factor IX per kilogram of body weight may increase plasma activity of factor IX by 1.3% (0.013 IU/ml) of normal activity.
?1 IU of factor VII per kg of body weight increases plasma activity of factor VII by 1.7% (0.017 IU/ml) of normal activity.
?1 IU of factor II per kg of body weight increases plasma activity of factor II by 1.9% (0.019 IU/ml) of normal activity.
?1 IU of factor X per kg of body weight increases plasma activity of factor X by 1.9% (0.019 IU/ml) of normal activity.
The dosage of a specific factor administered is expressed in International Units (IU), which are related to the current WHO standard for each factor. The plasma activity of a specific coagulation factor is expressed as a percentage (relative to normal plasma) or in International Units (relative to the international standard for the specific coagulation factor).
One International Unit (IU) of coagulation factor activity is equivalent to the amount contained in 1 ml of normal human plasma.
For example, the calculation of the required dose of factor X is based on the finding that 1 International Unit (IU) of factor X per kg of body weight increases plasma activity of factor X by 0.019 IU/ml.
The required dose is determined using the following formula:
Required Units = body weight [kg] x desired increase in factor X [IU/ml] x 53, where 53 (ml/kg) is the reciprocal of the estimated recovery.
Note that the calculation is based on data from patients who received vitamin K antagonists. A calculation based on data from healthy volunteers would provide a lower estimate of the required dose.
If the individual recovery is known, this value should be used in the calculation.
Product-specific information is available from clinical trials with healthy volunteers (N = 15), from the neutralization of vitamin K antagonists in the treatment of severe bleeding or perioperative prophylaxis of bleeding (N = 98, N = 43).
