What is Descovy?
Descovy is a prescription medicine approved by the U.S.(FDA) for the treatment of HIV infection in adults and children 12 years of age and older who weigh at least 77 pounds (35 kilograms). Descovy is always used in combination with other HIV medicines.
Descovy contains the following two different medicines combined in one tablet:

- Tenofovir alafenamide – another HIV medicine (also an NRTI)
