Atripla is not approved for the treatment of hepatitis B virus (HBV) infection. People coinfected with HIV and HBV who stopped taking emtricitabine or tenofovir disoproxil fumarate, which are two anti-HIV medicines included in Atripla, had severe worsening of their HBV infections.
While taking Atripla, it is important to keep all of your appointments with your health care provider.
Atripla is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults. Atripla can be used alone as a complete treatment regimen or in combination with other anti-HIV medicines.
Atripla contains the following three anti-HIV medicines combined in one pill: efavirenz, emtricitabine, and tenofovir disoproxil fumarate. Emtricitabine and tenofovir disoproxil fumarate are types of anti-HIV medicines called nucleoside reverse transcriptase inhibitors (NRTIs). Efavirenz is a type of anti-HIV medicine called a non-nucleoside reverse transcriptase inhibitor (NNRTI). The three drugs in combination help block HIV reverse transcriptase, an HIV enzyme. This prevents HIV from replicating and lowers the amount of HIV in the blood.
Atripla does not cure HIV/AIDS. It is not known if Atripla reduces the risk of passing HIV to other people.
Before taking Atripla, tell your health care provider:
