Which therapy is Ribavirin primarily used for?

Ribavirin is primarily used in the treatment of Hepatitis C, particularly when combined with other antiviral agents, such as peginterferon. Its mechanism of action involves inhibiting viral RNA synthesis and enhancing the immune response to the virus. This dual approach makes it effective in chronic Hepatitis C infections, which can lead to severe liver disease if untreated.

In addition to its use in Hepatitis C, ribavirin has also been used in the treatment of certain viral infections in specific contexts, such as respiratory syncytial virus (RSV), but its primary and most recognized application remains with Hepatitis C. This antiviral drug is not typically associated with treatments for influenza, HIV, or herpes simplex virus. Each of those conditions has specific antiviral medications that are preferred and more effective than ribavirin.
