Daclatasvir is an antiviral drug to treat hepatitis C. Daclatasvir should be used in combination with sofosbuvir. In addition to being used with sofosbuvir, daclatasvir can also be combined with other antiviral drugs, such as ribavirin.
Daclatasvir works by reducing the amount of hepatitis C virus in the body, so it can help the immune system to fight infection and help the liver recover. This drug cannot prevent transmission of hepatitis C.
