Recommended Dosage: The recommended dosage of ZERBAXA in patients 18 years and older with creatinine clearance (CrCl) greater than 50 mL/min is 1.5 gram (g) (ceftolozane 1 g and tazobactam 0.5 g) for cIAI and cUTI and 3 g (ceftolozane 2 g and tazobactam 1 g) for HABP/VABP administered every 8 hours by intravenous infusion over 1 hour. The duration of therapy should be guided by the severity and site of infection and the patient's clinical and bacteriological progress as shown in Table 8. (See Table 8.)

Dosage Adjustments in Patients with Renal Impairment: Dose adjustment is required for patients 18 years and older with CrCl 50 mL/min or less (Table 9). All doses of ZERBAXA are administered over 1 hour. For patients with changing renal function, monitor CrCl at least daily and adjust the dosage of ZERBAXA accordingly [see Patients with Renal Impairment under Precautions and Pharmacology: Pharmacokinetics under Actions]. (See Table 9.)
