Ribavirin is primarily used as an antiviral medication to treat severe respiratory syncytial virus (RSV) infections in infants and young children. It is also a key component in combination therapies for chronic hepatitis C, often paired with interferon-alpha to enhance its effectiveness. Additionally, Ribavirin has been explored for its potential in treating other viral infections, such as Lassa fever and certain hemorrhagic fevers, due to its broad-spectrum antiviral properties. In some cases, it is administered via inhalation for respiratory infections or orally for systemic viral conditions. Its ability to inhibit viral RNA synthesis makes it a valuable tool in managing various viral diseases.
