Mild or moderate renal dysfunction: No adjustment recommended.
Severe renal dysfunction (estimated glomerular filtration rate less than 30 mL/min/1.73 m2): Data not available

Comments:
-Safety and efficacy not established in patients with severe renal dysfunction; dose not established due to higher exposures of the main sofosbuvir metabolite.

Liver Dose Adjustments

Precautions

US BOXED WARNING:
-RISK OF HBV REACTIVATION IN PATIENTS COINFECTED WITH HCV AND HBV: All patients should be tested for evidence of current/prior HBV infection before starting this drug. HBV reactivation has been reported during or after completion of HCV direct-acting antiviral therapy in HCV/HBV-coinfected patients who were not receiving HBV antiviral therapy; some cases resulted in fulminant hepatitis, hepatic failure, and death. HCV/HBV-coinfected patients should be monitored for hepatitis flare or HBV reactivation during HCV therapy and posttherapy follow-up; appropriate patient management for HBV infection should be started as clinically indicated.

Safety and efficacy have not been established in patients younger than 18 years.

Consult WARNINGS section for additional precautions.

Dialysis

ESRD requiring hemodialysis: Data not available

Comments:
-Safety and efficacy not established in ESRD patients requiring hemodialysis; dose not established due to higher exposures of the main sofosbuvir metabolite.
