Elbasvir, Grazoprevir Overview

• The combination of elbasvir and grazoprevir is used alone or in combination with ribavirin (Copegus, Rebetol, Ribasphere, Virazole) to treat a certain type of chronic (long-term) hepatitis C infection (swelling of the liver caused by a virus) in adults and children 12 years of age or older.
