Key takeaways
Emtricitabine (Emtriva) and Descovy (emtricitabine/tenofovir alafenamide) are both used to treat and prevent HIV, but they have some key differences. Emtricitabine (Emtriva) is a single medication, while Descovy is a combination of two antiretrovirals (ARVs). Both medications must be combined with other HIV ARVs for effective treatment of HIV. However, Descovy is a complete regimen for HIV pre-exposure prophylaxis (PrEP). Descovy is preferred for PrEP but is not effective for females at risk of HIV through receptive vaginal sex. Emtricitabine (Emtriva) is available as both a capsule and an oral solution, whereas Descovy is only available as a tablet. Both medications require regular lab tests to monitor their effectiveness and potential side effects, but Descovy is noted to be safer for the kidneys and bones compared to another similar medication, Truvada. Additionally, both medications can worsen hepatitis B if stopped suddenly, so it's important to follow your healthcare provider's instructions closely.
