Zidovudine (ZDV), also known as azidothymidine (AZT), was the first antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use in combination with other antiretrovirals.[6] It may be used to prevent mother-to-child spread during birth or after a needlestick injury or other potential exposure.[6] It is sold both by itself and together as lamivudine/zidovudine and abacavir/lamivudine/zidovudine.[6] It can be used by mouth or by slow injection into a vein.[6]

Common side effects include headaches, fever, and nausea.[6] Serious side effects include liver problems, muscle damage, and high blood lactate levels.[6] It is commonly used in pregnancy and appears to be safe for the fetus.[6] ZDV is of the nucleoside analog reverse-transcriptase inhibitor (NRTI) class.[6] It works by inhibiting the enzyme reverse transcriptase that HIV uses to make DNA and therefore decreases replication of the virus.[6]

Zidovudine was first described in 1964.[7] It was resynthesized from a public-domain formula by Burroughs Wellcome.[8] It was approved in the United States in 1987 and was the first treatment for HIV.[6][9] It is on the World Health Organization's List of Essential Medicines.[10][11] It is available as a generic medication.[6]
