What Is Peginterferon Alfa-2a?
Peginterferon alfa-2a is an antiviral prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic hepatitis B virus (HBV) infection and chronic hepatitis C virus (HCV) infection. HBV and HCV infections are 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 infected with HIV -- than in people with healthy immune systems.
The Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents, 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), includes recommendations on the use of peginterferon alfa-2a to treat HBV and HCV infections in people also infected with HIV.
In addition to recommendations for the medicine's use in treating chronic HBV and HCV infections, the guidelines include recommendations on the "off-label" use of peginterferon alfa-2a to treat acute HCV infection in HIV-infected individuals. "Off-label" use refers to use of an FDA-approved medicine in a manner different from that described on the medicine label. Good medical practice and the best interests of a patient sometimes require that a medicine be used "off-label."
The above may not include all of the HIV-related uses of peginterferon alfa-2a recommended in the Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents. Some recommended uses, such as uses in certain rare circumstances, may have been omitted.
