Patient Education

Ledipasvir and Sofosbuvir


The combination of ledipasvir and sofosbuvir is used alone or in combination with ribavirin (Copegus, Rebetol, Ribasphere, others) to treat certain types of chronic hepatitis C (an ongoing viral infection that damages the liver) in adults and children 3 years of age and older. Sofosbuvir is in a class of antiviral medications called nucleotide polymerase inhibitors. It works by decreasing the amount of hepatitis C virus (HCV) in the body. Ledipasvir 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.
