Ribavirin is used in combination with other antiviral medications (such as interferon, sofosbuvir) to treat chronic (long-lasting) hepatitis C, a viral infection of the liver. Chronic hepatitis C infection can cause serious liver problems such as scarring (cirrhosis), or liver cancer. Ribavirin works by reducing the amount of hepatitis C virus in your body, which may help your liver recover.
It is not known if this treatment can prevent you from passing the virus to others. Do not share needles, and practice "safer sex" (including the use of latex condoms) to lower the risk of passing the virus to others.
