The recommended dose of ASPARLAS is 2,500 units/m2 given intravenously no more frequently than every 21 days.
Premedicate patients with acetaminophen, an H-1 receptor blocker (such as diphenhydramine), and an H-2 receptor blocker (such as famotidine) 30-60 minutes prior to administration of ASPARLAS to decrease the risk and severity of both infusion and hypersensitivity reactions [see Warnings and Precautions (5.1)].
