Ribavirin is an antiviral drug that is a synthetic nucleoside that inhibits many DNA and RNA viruses and its mechanism is unclear. The US Food and Drug Administration only permits the treatment of hepatitis C, human respiratory fusion virus, and certain haemorrhagic fever with long-acting interferon therapy. Ribavirin was synthesized by Joseph T. Witkowski, an ICN pharmaceutical company in 1970. FDA clearly pointed out that ribavirin is not suitable for the treatment of influenza, and strict indications, and the abuse of ribavirin to treat a variety of viral infections in China is very common.

Ribavirin is an anti-viral drug indicated for severe RSV infection (individually), hepatitis C infection (used in conjunction with peginterferon alfa-2b or peginterferon alfa-2a) and other viral infections. Ribavirin is a prodrug, which when metabolised resembles purine RNA nucleotides. In this form it interferes with RNA metabolism required for viral replication. How it exactly affects viral replication is unknown; many mechanisms have been proposed for this (see Mechanisms of Action, below) but none of these has been proven to date. Multiple mechanisms may be responsible for its actions.
