Patient Education

Elbasvir and Grazoprevir


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). Elbasvir is in a class of antiviral medications called HCV NS5A inhibitors. It works by stopping the virus that causes hepatitis C from spreading inside the body. Grazoprevir is in a class of medications called protease inhibitors. It works by decreasing the amount of hepatitis C virus (HCV) in the body. It is not known if elbasvir and grazoprevir prevent the spread of hepatitis C to other people.
