Ciprofloxacin Dosing in Chronic Kidney Disease

Introduction to Ciprofloxacin Dosing

For patients with chronic kidney disease (CKD), the American College of Clinical Pharmacology recommends reducing ciprofloxacin dose by 50% when creatinine clearance falls below 30 mL/min, maintaining the standard 12-hour dosing interval rather than extending it 1

For moderate-to-severe CKD (CrCl <30 mL/min), the Infectious Diseases Society of America suggests reducing the dose by 50% to 250 mg every 12 hours (oral) 1
For end-stage renal disease on hemodialysis, the National Kidney Foundation recommends administering 250-500 mg every 24 hours post-dialysis 2
For intravenous formulation in end-stage renal disease on hemodialysis, the National Kidney Foundation suggests 200-400 mg IV every 24 hours, given after dialysis session 2

The FDA and clinical guidelines recommend against assuming normal dosing is safe based on "normal" serum creatinine alone in elderly patients or those with reduced muscle mass, as this can mask severe renal impairment 3
The American Society of Nephrology advises against extrapolating dosing recommendations between different fluoroquinolones, as levofloxacin requires different adjustments 2, 3
