Treatment Description: Ribavirin (RBV) is a nucleoside analogue. Ribavirin is used in combination with direct acting antiviral treatments to stop viruses from reproducing and spreading. It does this by disturbing a virus’s way of copying itself and changing a body’s immune response towards viruses. This gives a treatment the best possible chance to cure.
Traditionally, ribavirin has been part of a treatment combination with pegylated interferon (Pegasys). However, stand-alone pills are now used with the treatments. See below for more about treatments that are combined with ribavirin to create interferon-free combinations.
