Official answer

by Drugs.com

Yes. The FDA approved Descovy (emtricitabine and tenofovir alafenamide) for pre-exposure prophylaxis (PrEP) in October 2019 to help reduce the risk of HIV-1 infection.

What is PrEP?

PrEP (pre-exposure prophylaxis) is an HIV prevention strategy where people who do not have HIV take medication daily to lower their risk of acquiring the virus if exposed.

What is Descovy?

Descovy is a combination of two HIV nucleoside analog reverse transcriptase inhibitors (NRTIs):

  • Emtricitabine
  • Tenofovir alafenamide

It was first approved by the FDA in 2016 for the treatment of HIV-1 infection and later for PrEP.

Who Can Use Descovy for PrEP?

Descovy is FDA-approved for PrEP in:

  • At-risk, adult and adolescent HIV-negative men and transgender women (≥35 kg)

Who Should NOT Use Descovy for PrEP?

Descovy is not approved for:

  • Cisgender women or individuals at risk of HIV from vaginal sex, as its effectiveness has not been studied in this population.

How is Descovy Taken?

Descovy is an oral tablet taken once daily with or without food.

Summary

Descovy is an effective PrEP option for HIV prevention in eligible populations, but it is not recommended for individuals at risk through vaginal sex. A healthcare provider can help determine the most suitable PrEP option based on individual risk factors and health needs.

Descovy is the second medicine approved for PrEP, after the approval of Truvada (emtricitabine and tenofovir disoproxil fumarate) in 2012.
