It may be used for all genotypes.
- Ribavirin was approved by the U.S. Food and Drug Administration for use by people living with hepatitis C in 1998.
- The cure rates of ribavirin depend on the treatment regimen it is prescribed with, along with genotype, prior treatment and the presence of cirrhosis.
