The combination of efavirenz, lamivudine, and tenofovir is used to treat HIV in adults and children. Efavirenz is in a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). Lamivudine and tenofovir are in a class of medications called nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs). They work by decreasing the amount of HIV in the body. Although efavirenz, lamivudine and tenofovir will not cure HIV, these medications 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 lifestyle changes may decrease the risk of getting or transmitting the HIV virus to other people.
