Head-to-headTruvada vs Descovy: which daily PrEP is right for you?
They're the two daily PrEP pills, and they protect against HIV equally for anal sex. The difference comes down to four things: your kidneys and bones, your anatomy/exposure, your weight/lipids, and your budget. Here's the honest comparison and a one-line rule.
Truvada vs Descovy at a glance
| Factor | Truvada (TDF/FTC) | Descovy (TAF/FTC) |
|---|---|---|
| HIV protection (anal) | ✅ ~99% | ✅ ~99% |
| Approved for vaginal sex | ✅ Yes | 🚫 No |
| Kidneys | monitor eGFR | minimal impact |
| Bone density | small loss (usually reversible) | negligible |
| Weight / lipids | neutral | ~1–3 kg gain, lipids up a little |
| Cost | cheap (generic) | brand-only, pricier |
So — which should you choose?
- Choose Truvada if your kidneys and bones are healthy, you want the low-cost generic, or you're exposed vaginally (Descovy isn't approved for that).
- Choose Descovy if you have reduced kidney function, osteoporosis/fracture risk, or tenofovir side effects — and your exposure is anal.
- Want no daily pill at all? Look past both to an injection — see the full comparison including Apretude and lenacapavir.

Truvada vs Descovy — FAQ
Are they equally effective?
Yes, for anal sex both are about 99% effective when taken as prescribed. The differences are about side effects, approvals and cost — not protection.
Why is Descovy not for women?
It wasn't studied for vaginal exposure, so it isn't approved for it. Women should use Truvada, Apretude or lenacapavir.
Does Descovy cause weight gain?
It's associated with a modest gain (about 1–3 kg on average) and small lipid changes, whereas Truvada is weight-neutral.
Should I switch?
Consider it for kidney/bone concerns or tenofovir side effects (with anal exposure). Otherwise generic Truvada is a solid, cheaper choice — decide with your provider.
