Reyataz is used with other medications to treat human immunodeficiency virus (HIV) infection. HIV causes the immune system to break down so that it can no longer fight off other infections. This leads to acquired immune deficiency syndrome (AIDS).
HIV thrives by taking over the immune system's vital CD4 cells (white blood cells) and using their inner workings to make additional copies of itself. Reyataz belongs to a class of HIV drugs called protease inhibitors, which work by interfering with an important step in the virus's reproductive cycle.
Reyataz is approved for used only in combination with other anti-HIV medications.
