What Is Ribavirin 200mg?
Ribavirin is a nucleoside antiviral medication sold under the brand name Rebetol. It is prescribed together with an interferon-based medicine to treat chronic hepatitis C virus (HCV) infection in adults and in children 3 years and older. Ribavirin is not effective when taken by itself and is only used as part of a combination regimen. It works by interfering with the virus's ability to multiply, which helps combination therapy reduce the amount of hepatitis C virus in the body.
