Advisory information

contraindications
• History of anaphylactic or severe systemic reaction to human immune globulins (4)
• IgA deficiency with antibodies against IgA and a history of IgA hypersensitivity (4)
Special warnings and precautions

WARNING: INTERACTIONS WITH GLUCOSE MONITORING SYSTEMS AND THROMBOSIS
See full prescribing information for complete boxed warning.
• Maltose in immune globulin products, including ANTHRASIL, may give falsely high blood glucose levels with some blood point-of-care glucose testing systems (for example those based on the GDH-PQQ or glucose-dye-oxidoreductase methods) resulting in inappropriate administration of insulin and life-threatening hypoglycemia. To avoid interference by maltose contained in ANTHRASIL, perform blood glucose measurements in patients receiving ANTHRASIL with a glucose-specific method (monitor and test strips).
• Thrombosis may occur with immune globulin products, including ANTHRASIL. Risk factors may include advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling vascular catheters, hyperviscosity and cardiovascular risk factors. Thrombosis may occur in the absence of known risk factors.
• For patients at risk of thrombosis, administer ANTHRASIL at the minimum infusion rate practicable. Ensure adequate hydration in patients before administration. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk of hyperviscosity.



• Hypersensitivity reactions including anaphylaxis (5.1)
• Interference with blood and urine glucose testing (5.2, 5.9)
• Thrombosis may occur. Monitor patients at risk (5.3)
• Monitor renal function and urine output in patients at risk of acute renal dysfunction/failure (5.4)
• Infuse ANTHRASIL at the minimum rate practicable in patients at risk of thrombosis or renal failure (5.5)
• Monitor for clinical signs and symptoms of hemolysis and hemolytic anemia (5.6)
• Aseptic meningitis syndrome (AMS) (5.7)
• Transfusion-related Acute Lung Injury (TRALI) (5.10)
• Transmission of infectious agents from human plasma (5.11)

Adverse reactions

The most common adverse reactions to ANTHRASIL observed in >5% of healthy volunteers in clinical trials were headache, infusion site pain and swelling, nausea, and back pain (6.1).
