Estimated GFR less than 15 mL/min/1.73 m2: 1 g IV every 12 hours
Comments:
- Estimated GFR (eGFR) based on the Modification of Diet in Renal Disease equation.
- Serum creatinine levels and eGFR should be monitored at least daily in patients with changing renal function; the dose of this drug should be adjusted accordingly.
- Total duration of therapy is for up to 14 days.
Liver Dose Adjustments

Administration advice:
- Administer all doses by IV infusion over 3 hours.
- Must complete IV infusion of the diluted solution within 4 hours if stored at room temperature or 22 hours if stored refrigerated.
Storage requirements:
- Powder (prior to constitution): Store vials at 20C to 25C (68F to 77F); excursions permitted to 15C to 30C (59F to 86F).
- Diluted solution: May store at room temperature or refrigerated at 2C to 8C (36F to 46F); IV infusion must be completed within 4 or 22 hours, respectively.
Reconstitution/preparation techniques:
- Constitute vial(s) with 0.9% Sodium Chloride Injection, USP; mix gently to dissolve.
- The constituted solution must be diluted further (immediately) in a 0.9% Sodium Chloride Injection, USP infusion bag prior to IV infusion.
- The manufacturer product information should be consulted.
IV compatibility:
- Only compatible with 0.9% Sodium Chloride Injection, USP
- Compatibility with other drugs not established.
General:
- Culture and susceptibility information should be considered when selecting/modifying antibacterial therapy or, if no data are available, local epidemiology and susceptibility patterns may be considered when selecting empiric therapy.
- Final infusion concentration (after dilution): 4 to 16 mg/mL; the manufacturer product information should be consulted.
Monitoring:
- Renal: Renal function in elderly patients; serum creatinine levels and eGFR in patients with changing renal function (at least daily)
Patient advice:
- Avoid missing doses and complete the entire course of therapy.
- Do not operate machinery or motorized vehicles until it is reasonably well established that this drug is well tolerated.
- Consult physician at once if watery and bloody stools (with or without stomach cramps and fever) develop.
