Other Info

  • Warning: Patients who are coinfected with hepatitis B and C who take this medication may be at risk of hepatitis B virus (HBV) reactivation. Before taking this medication, be sure your doctor has tested you for evidence of current or prior hepatitis B virus infection.  HBV reactivation has been reported in HCV/HBV coinfected patients who were undergoing or had completed treatment with HCV direct acting antivirals and were not receiving HBV antiviral therapy. Some cases have resulted in serious hepatitis flares, liver failure, and death. 
  • Pregnant women or those who are trying to become pregnant should not take Harvoni if it is prescribed with ribavirin. Women of childbearing age and their male sexual partners must use two forms of birth control throughout treatment and for six months after treatment if ribavirin is prescribed.
