Precautions

US BOXED WARNING(S): THROMBOSIS
-Thrombosis may occur with immune globulin products.
-Risk factors include: advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, estrogen use, indwelling central venous catheters, hyperviscosity, and cardiovascular risk factors.
-Thrombosis may occur in the absence of known risk factors.
Recommendations:
-For patients at risk of thrombosis, administer at the minimum dose and infusion rate practicable.
-Ensure adequate hydration of patients before administration.
-Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity.


Safety and efficacy have not been established in patients younger than 2 years.
