Antibiotic Renal Adjustment Key Points
Drug
When to use
Bedside reminder of renal thresholds and the major safety pitfalls (cefepime neurotoxicity, acyclovir crystal nephropathy). Follow the label for exact doses.
How it works
Per-drug CrCl bands and safety notes; ARC (CrCl > 130) needs higher doses / extended infusion, not lower.
Key points
- Cefepime can cause encephalopathy even after renal adjustment — consider TDM.
- Hydrate and infuse acyclovir slowly to prevent crystal nephropathy.
- Nitrofurantoin: avoid below CrCl 30.
- Augmented renal clearance underexposes β-lactams — increase the dose.
