How FUZEON May Work

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.
