elbasvir - grazoprevir
How does this medication work? What will it do for me?
This is a combination medication that contains elbasvir and grazoprevir. Both medications belong to the group of medications called antivirals. This medication is used by adults, alone and with other medications, to treat certain genetic variations of chronic (long-term) hepatitis C virus infection (CHC).
Elbasvir and grazoprevir work in different ways to prevent the hepatitis C virus (HCV) from multiplying. By stopping the virus from reproducing, they quickly reduce the levels of HCV in the body.
