“ALERT: US Boxed Warning
Hepatitis B virus reactivation:
Test all patients for evidence of current or prior hepatitis B virus (HBV) infection before initiating treatment with sofosbuvir/velpatasvir/voxilaprevir. HBV reactivation has been reported in hepatitis C virus (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 fulminant hepatitis, hepatic failure, and death. Monitor HCV/HBV coinfected patients for hepatitis flare or HBV reactivation during HCV treatment and post-treatment follow-up. Initiate appropriate patient management for HBV infection as clinically indicated.”
How does this medication work?
Sofosbuvir is a prodrug that is converted to its pharmacologically active form GS-461203. The active form inhibits NS5B RNA-dependent RNA polymerase, also essential for viral replication, and acts as a chain terminator.
Velpatasvir is an inhibitor of the HCV NS5A protein, which is also required for viral replication.
Voxilaprevir is a noncovalent, reversible inhibitor of the NS3/4A protease, which is required for proteolytic cleavage of the HCV-encoded polyprotein which is essential for viral replication.
How should I take this medication?
Oral: One tablet (Sofosbuvir 400 mg, velpatasvir 100 mg, and voxilaprevir 100 mg) once daily for 12 weeks in combination with other agents that vary with virus genotype
