⚠️ Warnings
Seek the advice of a specialist experienced in the treatment of coagulation disorders.
In patients with acquired deficiency of vitamin K-dependent coagulation factors (e.g. deficiency induced by treatment with vitamin K antagonists), Beriplex should only be used when rapid correction of prothrombin complex levels is necessary, such as in major bleeding or emergency surgery. In other cases, reduction of the vitamin K antagonist dose and/or administration of vitamin K is usually sufficient.
Patients receiving vitamin K antagonists have an underlying hypercoagulable state, which may be exacerbated by infusion of human prothrombin complex.
In congenital deficiency of any vitamin K-dependent factor, a specific coagulation factor product should be used when available.
If an allergic or anaphylactic reaction occurs, administration of Beriplex should be stopped immediately (e.g. stop injection) and appropriate treatment must be initiated. Treatment depends on the nature and severity of the adverse reaction. In case of shock, standard anti-shock treatment must be initiated immediately.
There is a risk of thrombosis or disseminated intravascular coagulation when patients with congenital or acquired deficiency are treated with human prothrombin complex, especially with repeated dosing. The risk may be higher in the treatment of isolated factor VII deficiency, since the other vitamin K-dependent coagulation factors with longer half-lives may accumulate to levels substantially above normal. Patients receiving human prothrombin complex concentrates should be closely monitored for signs of intravascular coagulation or thrombosis.
Due to the risk of thromboembolic complications, close monitoring is recommended when administering Beriplex, particularly in patients with a history of coronary heart disease, patients with liver disease, peri- and postoperative patients, neonates, or other patients at risk of thromboembolic events or disseminated intravascular coagulation, or with concurrent inhibitor deficiency.
In each of these situations, the potential benefit of treatment with Beriplex should be weighed against the risk of these complications.
In patients with disseminated intravascular coagulation, replacement of prothrombin complex coagulation factors may be necessary under certain circumstances. However, such replacement should only be carried out after resolution of the consumptive state (e.g. treatment of the underlying cause, sustained normalisation of antithrombin III levels).
Reversal of vitamin K antagonist therapy exposes patients to the thromboembolic risk of the underlying disease. Resumption of anticoagulation should be carefully considered as soon as possible.
Adverse reactions may include the development of heparin-induced thrombocytopenia type II (HIT type II). The characteristic features of HIT are a platelet count decrease of > 50 percent and/or the occurrence of new or unexplained thromboembolic complications during heparin therapy. The onset is usually 4 to 14 days after initiation of heparin therapy, but may occur within 10 hours in patients who have recently received heparin (within the past 100 days).
Nephrotic syndrome has been reported in isolated cases following attempted immune tolerance induction in haemophilia B patients with factor IX inhibitors and a history of allergic reaction.
No data are available on the use of Beriplex in cases of perinatal bleeding due to vitamin K deficiency in neonates.
Beriplex contains up to 343 mg sodium (approximately 15 mmol) per 100 ml. This should be taken into consideration in patients on a sodium-restricted diet.
Viral safety
Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection, and the inclusion of effective manufacturing steps for the inactivation/removal of viruses. Despite these measures, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents cannot be totally excluded. This also applies to any unknown or emerging viruses or other pathogens.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), and for the non-enveloped hepatitis A virus (HAV) and parvovirus B19.
Appropriate vaccination (against hepatitis A and B) should be considered for patients receiving regular or repeated administration of prothrombin complex products derived from human plasma.
It is strongly recommended that every time Beriplex is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.
