Prior to initial dosing, assess patients for ACLF Grade 3 and obtain patient baseline oxygenation level. Monitor patient oxygen saturation with pulse oximetry. Recommended Dosage Regimen: Days 1 to 3 administer TERLIVAZ 0.85 mg (1 vial) intravenously every 6 hours. Day 4: Assess serum creatinine (SCr) versus baseline. If SCr has decreased by at least 30% from baseline, continue TERLIVAZ 0.85 mg (1 vial) intravenously every 6 hours. If SCr has decreased by less than 30% from baseline, dose may be increased to TERLIVAZ 1.7 mg (2 vials) intravenously every 6 hours. If SCr is at or above baseline value, discontinue TERLIVAZ. Continue TERLIVAZ until 24 hours after two consecutive SCr ≤1.5 mg/dL values at least 2 hours apart or a maximum of 14 days. See full prescribing information for instructions on preparation and administration. Flush IV line after administration.
