FAQs
How do I take Descovy for PrEP?
The typical Descovy PrEP dosage is one tablet (200 mg emtricitabine + 25 mg tenofovir alafenamide) taken once daily, with or without food[1][3][5].
Who is Descovy PrEP approved for?
Descovy PrEP is FDA-approved for adults and adolescents at risk for HIV through sexual contact; current guidelines do not recommend it for cisgender women with receptive vaginal exposure—Truvada remains the preferred option for that group[1][3].
What are the main side effects of Descovy PrEP?
Common, usually mild side effects include diarrhea, nausea, headache, fatigue, and stomach pain; serious side effects like kidney problems are rare but possible[2][6][8].
How does Descovy compare to Truvada for PrEP?
Both offer about 99% protection when taken daily, but Descovy generally has a better kidney and bone safety profile due to its use of tenofovir alafenamide (TAF) rather than tenofovir disoproxil fumarate (TDF)[1]. Truvada, however, is the only FDA-approved PrEP option for those at vaginal exposure risk.
Can I use the “2-1-1” dosing schedule with Descovy?
No, the “2-1-1” on-demand regimen is only FDA-approved for Truvada in men who have sex with men. Descovy PrEP should be taken daily for maximum HIV protection[1][3][5].
