What are the side effects of ribavirin?


Ribavirin (Copegus«, Rebetol« and Ribasphere«) is an oral antiviral medication, which is taken daily. It can be given as oral inhalation to treat a type of viral pneumonia in infants. It is also used in the treatment of viral hepatitis C. However, it is not used alone to treat hepatitis C. Instead, it is taken in combination with interferon (Intron-A« and Infergen«) or pegylated interferon (Pegasys« and Peg-Intron«). Ribavirin is believed to work by interfering with the survival and multiplication of the hepatitis C virus. There may be other uses for ribavirin that are not yet approved by the FDA (Food and Drug Administration).
