What IBAVYR is used for
IBAVYR Tablets contain the active ingredient ribavirin. Ribavirin belongs to a group of medicines called antivirals.
IBAVYR is used in combination with other oral agents for the treatment of chronic hepatitis C (CHC). CHC is a viral infection of the liver. There are different types of the hepatitis C virus, referred to as genotypes. If this viral infection is not managed in some people, the liver becomes badly damaged and scarred. This is called cirrhosis. Cirrhosis can cause the liver to stop working. CHC may also be associated with the development of hepatocellular carcinoma.
IBAVYR is not effective when used alone and must only be used in combination with other oral agents. For more information please refer to the respective Consumer Medicine Information of the other oral agent used during the treatment.
This medicine is available only with a doctor's prescription.
