Genvoya Overview

Reviewed: November 5, 2015

Genvoya is a prescription medication used to treat human immunodeficiency virus (HIV). It is a single product containing 4 medications: elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide. 

Elvitegravir belongs to a group of drugs called HIV integrase strand transfer inhibitor (HIV-1 INSTI). Cobicistat belongs to a group of drugs called CYP3A inhibitors. Cobicistat helps to keep the other medications in the body longer so that the medication will have a greater effect. Emtricitabine and tenofovir belong to a group of drugs called nucleoside reverse transcriptase inhibitors. Together these drugs work to decrease the presence of HIV in the blood.

This medication is available in tablet form and is typically taken once a day with food.

Common side effects of Genvoya include nausea and increases in cholesterol.

Genvoya Usage

Take Genvoya exactly as prescribed.

Do not miss a dose of Genvoya. If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of Genvoya at the same time.
