An Overview of PegIntron (Peginterferon Alfa-2b)

September 7, 2017

Brand Name: PegIntron
Other Names: PEG-interferon alfa 2b (HCV), pegIFN alfa-2b (HCV), pegylated-interferon alfa 2b (HCV)
Drug Class: Opportunistic Infections and Coinfections


What Is Peginterferon Alfa-2b?

Peginterferon alfa-2b is an antiviral prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic hepatitis C virus (HCV) infection. HCV is an HIV-related opportunistic infection. An opportunistic infection is an infection that occurs more frequently or is more severe in people with weakened immune systems -- such as those living with HIV -- than in people with healthy immune systems. To learn how HIV and HCV infection are connected, read the AIDSinfo HIV and Hepatitis C fact sheet.

The Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents (Adult OI Guidelines), prepared by the Centers for Disease Control and Prevention (CDC), the National Institutes of Health (NIH), and the HIV Medicine Association of the Infectious Diseases Society of America (IDSA-HIVMA), refer readers to the Hepatitis C Guidance: AASLD-IDSA Recommendations for Testing, Managing, and Treating Adults Infected with Hepatitis C Virus for recommendations on the treatment of HCV infection in people with HIV. The Hepatitis C Guidance is prepared by the American Association for the Study of Liver Diseases (AASLD), the Infectious Diseases Society of America (IDSA), and the International Antiviral Society-USA (IAS-USA). Although peginterferon alfa-2b is approved for the treatment of chronic HCV infection, the IDSA-AASLD Hepatitis C Guidance recommends against the use of peginterferon-containing regimens to treat HCV infection, including in people with HIV. New, recently approved HCV drugs offer more effective, better tolerated treatment options.

Please refer to the Adult OI Guidelines and the IDSA-AASLD Hepatitis C Guidance for more information.

  • About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take.
