Virazide or Ribavirin is used primarily to treat hepatitis C and viral hemorrhagic fevers (which is an orphan indication in most countries). In this former indication the oral (capsule or tablet) form of ribavirin is used in combination with pegylated interferon alfa. Including in people coinfected with hepatitis B, HIV and in the pediatric population. Statins may improve this combination's efficacy in treating hepatitis C. Ribavirin is the only known treatment for a variety of viral hemorrhagic fevers, including Lassa fever, Crimean-Congo hemorrhagic fever, Venezuelan hemorrhagic fever, and Hantavirus infection, although data regarding these infections are scarce and the drug might be effective only in early stages. The aerosol form has been used in the past to treat respiratory syncytial virus-related diseases in children, although the evidence to support this is rather weak.  Ref:  Grossman lab.  Flu.
