The changing landscape of adverse drug events associated with chronic hepatitis C virus therapy

Treatment of chronic hepatitis C virus (HCV) therapy has rapidly changed since the approval of IFN in the 1990s. Early treatment brought about significant and therapy limiting adverse drug events (ADEs) such as anemia. Since the direct-acting antivirals were first approved in 2011 and then advanced in 2013, treatment-related ADEs and therapy discontinuations have rapidly decreased, while sustained virologic response rates have significantly increased. As the market for treating chronic HCV therapy has changed, so too has the ADE profile clinicians may need to manage.
