Enfuvirtide is an antiretroviral medicine. It is used for human immunodeficiency virus (HIV) infection. It slows the progress of HIV infection, but it is not a cure. HIV destroys cells in the body, called CD4 T cells. These cells are a type of white blood cell and are important because they are involved in protecting your body from infection. If left untreated, the HIV infection weakens your immune system so that your body cannot defend itself against bacteria, viruses and other germs. Enfuvirtide is known as a fusion inhibitor antiretroviral medicine - it works by stopping HIV from attaching to your CD4 cells to get inside them. By reducing the amount of virus getting into your cells, it helps to maintain the health of your immune system.
