Cephalexin Dosing With Stage 3B Chronic Kidney Disease
For patients with creatinine clearance (CrCl) 30 to 59 mL/min (consistent with CKD stage 3B), cephalexin does not require renal dose adjustment, but the maximum total daily dose should not exceed 1 g. [1]
Renal Function–Based Dose Adjustment
- CrCl 30 to 59 mL/min: No dose adjustment; maximum daily dose should not exceed 1 g. [1]
Practical Dosing Implication
- The intended total daily cephalexin dose should be capped at 1 g/day in CKD stage 3B (CrCl 30 to 44 mL/min) based on the labeled renal impairment dosing table. [1]
Monitoring Considerations
- Cephalexin should be administered with careful monitoring in the presence of impaired renal function (noting that the labeled renal dosing adjustments are based on CrCl thresholds). [2]
