WARNINGS / PRECAUTIONS
Concerns related to adverse effects: Thrombotic events: Observe closely for signs and symptoms of intravascular coagulation or thrombosis. High doses have been associated with thrombotic complications, including MI and DIC; single doses should not exceed 100 units/kg and daily doses should not exceed 200 units/kg. Use with caution when administering to patients with liver disease, postoperatively, neonates, or patients at risk of thromboembolic phenomena, disseminated intravascular coagulation or patients with signs of fibrinolysis due to the potential risk of thromboembolic complications.
Disease-related concerns: Hepatic impairment: Use with extreme caution in patients with hepatic impairment.
Dosage form specific issues: Factor VIII: Product contains minute amounts of factor VIII which may cause an anamnestic response. Human plasma: Product of human plasma; may potentially contain infectious agents which could transmit disease. Screening of donors, as well as testing and/or inactivation or removal of certain viruses, reduces the risk. Infections thought to be transmitted by this product should be reported to the manufacturer. Latex: Product packaging may contain natural rubber latex.
Other warnings/precautions: Appropriate use: Should only be used to control bleeding in patients with inhibitors resulting from coagulation factor deficiencies. Tests used to control improvement, such as aPTT, whole blood clotting time (WBCT), and thromboelastography (TEG), do not correlate with clinical efficacy. Dosing to normalize these values may result in DIC.
Antifibrinolytic Agents: May enhance the thrombogenic effect of Anti-inhibitor Coagulant Complex. Risk X: Avoid combination
PREGNANCY RISK FACTOR — C (show table)
PREGNANCY IMPLICATIONS — Reproduction studies have not been conducted.
LACTATION — Excretion in breast milk unknown/use caution
DIETARY CONSIDERATIONS — Contains sodium 8 mg/mL
MONITORING PARAMETERS — Monitor for control of bleeding; signs and symptoms of DIC (blood pressure changes, pulse rate changes, chest pain/cough, fibrinogen decreased, platelet count decreased, fibrin-fibrinogen degradation products, significantly-prolonged thrombin time, PT, or partial thromboplastin time); hypotension; have epinephrine ready to treat hypersensitivity reactions. Note: Tests used to control efficacy such as aPTT, WBCT, and TEG do not correlate with clinical improvement. Dosing to normalize these values may result in DIC.
