It has been reported that patients who are co-infected with Hepatitis B and C or patients who have had Hepatitis B in the past, could be at risk for hepatitis B reactivation. Hep B has been reported in HCV/HBV coinfected patients who were taking or had taken treatment with the Hep C direct acting antiviral and not receiving treatment for Hep B.
Prior to taking Mavyret, make sure your physician tests you for Hepatitis B antibodies and report any prior history of Hepatitis B or treatment for Hep B. Some cases have resulted in serious hepatitis reactivation, liver failure, and death.
Be sure to report pregnancy or breast feeding to your physician prior to taking Mavyret.
