What is Genvoya?

 

Genvoya is a once-daily combination antiretroviral medication used to treat HIV-1 in adults and adolescents aged 12 years and older with a body weight of at least 35 kg. It combines four antiviral drugs into one tablet, elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide to prevent the HIV virus from further multiplying in your body. Genvoya is manufactured by Gilead Sciences, Inc.

How does Genvoya work?

Genvoya is a combination tablet made up of elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide. Each drug works to minimize the viral load of the human immunodeficiency virus type 1 (HIV-1) in different ways. Elvitegravir works as an integrase inhibitor, while emtricitabine and tenofovir alafenamide are part of the NRTI class of drugs (nucleoside reverse transcriptase inhibitors). Cobicistat is used to boost the effects of elvitegravir and stops the enzymes that break down antiviral medicines.

The use of Genvoya does not cure HIV infection/AIDS. It is an HIV treatment that is used to reduce the viral load of HIV in the body until it is undetectable (HIV-1 RNA <50 copies/mL). This protects your immune system and helps stop HIV from being passed on to a partner during sex.

What doses of Genvoya are available?

Genvoya comes as a once-daily, film-coated tablet (labeled GSI 510) in a combined dosage of 150 mg elvitegravir (EVG), 150 mg cobicistat (COBI), 200 mg emtricitabine (FTC), and 10 mg tenofovir alafenamide (TAF). A healthcare provider may alter the dosage depending on the patient’s weight.

How do you use Genvoya?

Ensure you follow the treatment regimen given by your healthcare provider and read all prescribing information and FDA-approved product labeling, and the Medication Guide before taking Genvoya.

Genvoya should be taken once daily with food at the same time each day to maximize its effectiveness. If you forget a dose, take your missed dose as soon as you remember unless it is almost time for your next dose. Do not double-dose the medication.
