*Patients with DM are at increased risk for thromboembolic events; monitor carefully and do not exceed an infusion rate of 0.04 mL/kg/min.
Monitor the patient carefully throughout the infusion. Certain adverse drug reactions may be related to the rate of infusion. Slowing or stopping the infusion usually allows the symptoms to disappear promptly. Once the symptoms subside, the infusion may then be resumed at a lower rate.
Ensure that patients with pre-existing renal insufficiency are not volume depleted. For patients at risk of renal dysfunction or thromboembolic events, administer octagam 10% at the minimum infusion rate practicable, not to exceed 3.3 mg/kg/min (0.03 mL/kg/min). Discontinue octagam 10% if renal function deteriorates.
