Indications and Usage

Ribavirin tablets in combination with peginterferon alfa-2a are indicated for the treatment of adults with chronic hepatitis C virus infection who have compensated liver disease and have not been previously treated with interferon alpha.

Patients in whom efficacy was demonstrated included patients with compensated liver disease and histological evidence of cirrhosis (Child-Pugh class A) and patients with HIV disease that is clinically stable (e.g., antiretroviral therapy not required or receiving stable antiretroviral therapy).
Virus Diseases -- A general term for diseases produced by viruses.

Liver diseases -- Pathological processes of the LIVER.

HIV Infections -- any state of infection accompanied by evidence of HIV in the body (positive test for HIV genome, cDNA, proteins, antigens, or antibodies); may be medically asymptomatic or symptomatic; use AIDS when appropriate.


Ribavirin tablet is contraindicated in:Patients with known hypersensitivity to ribavirin tablets or to any component of the tablet.Women who are pregnant.Men whose female partners are pregnant.Patients with hemoglobinopathies (e.g., thalassemia major or sickle-cell anemia).Ribavirin tablets and peginterferon alfa-2a combination therapy is contraindicated in patients with:Autoimmune hepatitis.Hepatic decompensation (Child-Pugh score greater than 6; class B and C) in cirrhotic CHC monoinfected patients before or during treatment.

Hepatic decompensation with Child-Pugh score greater than or equal to 6 in cirrhotic CHC patients coinfected with HIV before or during treatment.
Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.

hemoglobinopathies -- A group of inherited disorders characterized by structural alterations within the hemoglobin molecule.

Cooley's anemia --

Sickle Cell Anemia -- A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.

Acquired Immunodeficiency Syndrome -- An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.

Ribavirin tablets must not be used alone because ribavirin monotherapy is not effective for the treatment of chronic hepatitis C virus infection.

The safety and efficacy of ribavirin tablets have only been established when used together with peginterferon alfa-2a (pegylated interferon alfa-2a, recombinant).Ribavirin tablets and peginterferon alfa-2a should be discontinued in patients who develop evidence of hepatic decompensation during treatment.There are significant adverse events caused by ribavirin tablets/peginterferon alfa-2a therapy, including severe depression and suicidal ideation, hemolytic anemia, suppression of bone marrow function, autoimmune and infectious disorders, pulmonary dysfunction, pancreatitis, and diabetes.

The peginterferon alfa-2a package insert and MEDICATION GUIDE should be reviewed in their entirety prior to initiation of combination treatment for additional safety information.
