Patient Education

Fostemsavir


Fostemsavir is used along with other medications to treat human immunodeficiency virus (HIV) infection in adults whose HIV could not be successfully treated with other medications, including their current therapy. Fostemsavir is in a class of medications called HIV attachment inhibitors. It works by decreasing the amount of HIV in the blood. Although fostemsavir does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting (spreading) the HIV virus to other people.
