Legend

  1. Renal function estimated for dosage adjustment mostly based on Cockcroft formula (CLCRT: creatinine clearance)
  2. For persons with creatinine clearance < 15 mL/min or persons on dialysis, a nephrologist should be consulted
  3. The drug package insert should be consulted for specific dose adjustments
  4. No dose adjustment on antibacterial loading dose 
  5. The product label does not recommend nirmatrelvir/ritonavir for patients with eGFR <30 mL/min. However, on the basis of clinical, modelling and patient data, an adjusted dose given at a lower frequency has been proposed for use in people with eGFR <30 mL/min and those on dialysis. The adjusted dose of nirmatrelvir/ritonavir was found to be safe and well tolerated in a small sample of 134 maintenance dialysis patients (Hiremath S et al. Clin J Am Soc Nephrol 2023).
