Patient Education

Ribavirin


Ribavirin is used with an interferon medication such as peginterferon alfa-2a [Pegasys] or peginterferon alpha-2b [PEG-Intron]) to treat hepatitis C in people who have not been treated with an interferon before. Ribavirin is in a class of antiviral medications called nucleoside analogues. It works by stopping the virus that causes hepatitis C from spreading inside the body. It is not known if treatment that includes ribavirin and another medication cures hepatitis C infection, prevents liver damage that may be caused by hepatitis C, or prevents the spread of hepatitis C to other people.
