How does this medication work? What will it do for me?
Ribavirin belongs to the group of medications known as antivirals. It is used to treat serious infections caused by the respiratory syncytial virus (RSV), which can cause severe lung infections in newborns and infants. Premature babies and infants with heart, lung, or immune system problems are most likely to be affected by this virus. Ribavirin works by killing RSV.
