What Is Ganciclovir?

Cytovene capsule

Ganciclovir is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of cytomegalovirus (CMV) retinitis (a viral Infection and inflammation of the eye's retina) in individuals with AIDS. Ganciclovir is also FDA-approved for the prevention of CMV disease in transplant recipients at risk for CMV diseases.

CMV diseases, including CMV retinitis, are opportunistic infections. 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. To learn more about opportunistic infections, read the AIDS_info_ What is an Opportunistic Infection? fact sheet.

Ganciclovir can also be used "off-label" to prevent and treat other opportunistic infections of HIV infection. "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."

How Is Ganciclovir Used in People With HIV?

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 HIV-related uses of ganciclovir. On-label, ganciclovir is recommended for the treatment of CMV retinitis. Ganciclovir is also recommended for use off-label to:

  • Prevent:

    • CMV retinitis from recurring (called secondary prophylaxis or maintenance therapy).
  • Treat:

    • Other types of CMV disease, including CMV pneumonitis (infection and inflammation of the lungs) and CMV neurological disease (infection and disease of the nervous system).
    • Two varicella zoster virus (VZV) diseases called progressive outer retinal necrosis and acute retinal necrosis, both of which are infection and necrotizing inflammation (causing tissue death) of the eye's retina.
    • Certain human herpesvirus 8 (HHV-8) diseases, including multicentric Castleman's disease (a disease of the lymph nodes).
