HIV causes a person to become more prone to illness, so infected people need treatment options. However, there is no cure for HIV. To help ease negative symptoms, drugs called anti-retroviral therapy (ART) are available. This treatment is also called high active anti-retroviral therapy (HAART). HAART treatment begins with one non-nucleoside reverse transcriptase inhibitor (NNRTI) and two nucleoside analogue reverse transcriptase inhibitors (NRTIs). The NRTI drug could be named zidovudine (AZT), tenofovir (TDF), andlamivudine (3TC), or emtricitabine (FTC).
