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.
Coadministration with rifampin
Safety and efficacy have not been established in patients younger than 18 years.
Consult WARNINGS section for additional precautions.
