Emtricitabine/rilpivirine/tenofovir (trade names Complera, Eviplera) is a fixed dose combination of antiretroviral drugs for the treatment of HIV.[1] The drug was co-developed by Gilead Sciences and Johnson & Johnson's Tibotec division and was approved by the Food and Drug Administration in August 2011, and by the European Medicines Agency in November 2011,[2] for patients who have not previously been treated for HIV.[3] It is available as a once-a-day single tablet. In Europe it is commercialized as Eviplera and in the US as Complera.[4] Emtricitabine/rilpivirine/tenofovir is indicated for treatment of HIV-1 in adults naïve to HIV-1 medications (where the virus has not developed resistance to these anti-HIV medications) and who have no more than 100,000 copies per mL of HIV-1 RNA in their blood (“viral load”).[5][6] Common[5][7] Serious[5][7] Contraindications Use of emtricitabine/rilpivirine/tenofovir with the following medicines is contraindicated, as they lead to reduced blood levels of rilpivirine and in turn reduce the effectiveness of emtricitabine/rilpivirine/tenofovir:[5][8]
