This product is used to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. This product contains 4 different medications: elvitegravir, cobicistat, emtricitabine, and tenofovir. Elvitegravir is known as an integrase inhibitor. Cobicistat helps elvitegravir work better. Emtricitabine is called a nucleoside reverse transcriptase inhibitor, while tenofovir is called a nucleotide reverse transcriptase inhibitor; they are often called NRTIs.
Elvitegravir/cobicistat/emtricitabine/tenofovir is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.
