UTI in Chronic Kidney Disease

CKD 4/5

 

Ref: Renal Drug Handbook

  • Avoid nitrofurantoin in patients with CKD 4 or 5.
  • Trimethoprim can be used in patients with CKD 3 (unless baseline K is high). Trimethoprim can cause a temporary increase in serum potassium and creatinine during treatment.

Ensure samples are marked with CKD 4 or 5 to allow lab to release sensitivities to cefalexin (ciprofloxacin for penicillin allergic patients)
