FUZEON blocks HIV outside CD4+ T cells—before the virus can enter and infect healthy cells.


FUZEON is designed to target HIV outside the CD4 Cells

  • FUZEON is always used with other anti-HIV medicines to treat adults and children ages 6 years and older with HIV infection.
  • Because of the way that FUZEON may work, FUZEON may be active against HIV that is resistant to other HIV medicines. So if you haven't been on FUZEON before and those other medicines have failed you, your virus may be sensitive to FUZEON. As with other HIV medicines, it is possible to develop resistance to FUZEON.



If you have a detectable viral load and have experienced treatment failure with previous drug regimens, FUZEON may be an option for you.

It may be time to talk to your healthcare provider about FUZEON if you have only 1 fully active agent in your current regimen.

To design a new regimen, your treatment history—as well as past and current resistance test results—should be used to identify at least 2 (preferably 3) fully active agents to combine with an optimized background antiretroviral (ARV) regimen (AI). A fully active agent is one that is likely to have ARV activity on the basis of your treatment history, drug-resistance testing, and/or a novel mechanism of action.1

Do not use FUZEON if you are allergic to any of the ingredients in FUZEON.
