The combination of lamivudine and zidovudine is used along with other medications to treat human immunodeficiency virus (HIV) infection. Lamivudine and zidovudine are in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). They work by decreasing the amount of HIV in the blood. Although the combination of lamivudine and zidovudine does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting (spreading) the HIV virus to other people.
