Zidovudine (also known as AZT) is used together with other medicines for the treatment of human immunodeficiency virus (HIV) infection. HIV is the virus that causes acquired immune deficiency syndrome (AIDS). Zidovudine is used to slow the progression of disease in patients infected with HIV who have advanced symptoms, early symptoms, or no symptoms at all. This medicine is also used to help prevent pregnant women who have HIV from passing the virus to their babies during pregnancy and at birth.

Zidovudine will not cure or prevent HIV infection or AIDS, however, it helps keep HIV 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. Zidovudine will not keep you from spreading HIV to other people. People who receive this medicine may continue to have the problems usually related to AIDS or HIV disease.

This medicine is available only with your doctor's prescription.
