Maraviroc is used together with other medicines to treat certain types of infection caused by the human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS). maraviroc is usually given to patients who have received HIV treatments in the past.
Maraviroc will not cure or prevent HIV infection or AIDS. It helps keep the HIV virus from reproducing, and appears to slow down the destruction of the immune system. This may help delay the development of problems that usually result from AIDS or HIV disease. Maraviroc will not keep you from spreading HIV to other people. People who receive maraviroc may continue to have some of the problems usually related to AIDS or HIV disease.
