What is elbasvir/grazoprevir?

Elbasvir/grazoprevir is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic (lasting a long time) hepatitis C virus (HCV) infection.

HCV is an 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.

What HIV-related opportunistic infections is elbasvir/grazoprevir used for?

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), and the Hepatitis C Guidance: AASLD-IDSA Recommendations for Testing, Managing, and Treating Adults Infected with Hepatitis C Virus, 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), both include recommendations on the HIV-related uses of elbasvir/grazoprevir to treat chronic HCV infection.

In addition to recommendations for the medicine's use in treating chronic HCV infection, the guidelines and the guidance include recommendations on the “off-label” use of elbasvir/grazoprevir 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.”

Women should also not become pregnant for 6 months after they stop taking ribavirin or for 6 months after their male partners stop taking ribavirin.
  • If you are breastfeeding or plan to breastfeed. Do not breastfeed if you are infected with HIV.
  • About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Elbasvir/grazoprevir may affect the way other medicines or products work, and other medicines or products may affect how elbasvir/grazoprevir works.
