The three choices at a glance
Oral PrEP — pros and cons
Pros
- Most studied — 14+ years of safety data
- Cheapest option (generic ~$30/mo retail)
- No needles, no clinic visits for administration
- Easy to stop (no long drug tail)
- On-demand/"2-1-1" dosing option for MSM
- Covered on every insurance formulary
- Works in every FDA-approved population including cisgender women (generic/Truvada)
Cons
- Requires daily adherence
- TDF can cause small kidney/bone effects (reversible)
- Pills must be stored and carried
- Privacy concerns if living with family who don't know
- Occasional GI side effects during start-up
- Descovy isn't approved for vaginal-sex exposure
Injectable PrEP — pros and cons
Pros
- No daily pill to remember
- Total adherence removed from your hands — once you show up, you're covered
- Private (no pills at home)
- In HPTN 083, Apretude was 69% more effective than daily PrEP in real-world use — entirely an adherence effect
- Yeztugo is twice-yearly — two visits covers the whole year
- Easier on kidneys and bones than TDF
Cons
- Requires clinic visits for each injection
- Injection site reactions common (mild, temporary)
- Long drug "tail" — if you stop, levels decline slowly over ~1 year (non-protective during tail)
- Often requires prior authorization
- Prescribers who can administer are not universal yet
- Higher list price (though $0 pathways exist)

Which one should you pick?
Oral generic TDF/FTC is the most cost-effective, best-studied PrEP available. If you can reliably take a daily pill — or already do for other meds — oral PrEP is the default recommendation. It's also the easiest to stop if you decide you don't want PrEP anymore, because there's no long tail.
Apretude is the go-to when daily adherence is genuinely difficult: unstable housing, traveling frequently, poor memory for daily habits, or living with people you don't want to out yourself to. Six visits a year is more than Yeztugo's two, but Apretude has more real-world insurance coverage right now and is often easier to get approved.
Two injections a year, and you're done. For people who travel, live far from clinics, or simply don't want to think about PrEP between visits, Yeztugo is a generational advance. The main catch is that insurance coverage is still catching up — as of early 2026, some plans require prior authorization or prefer Apretude.
Common situations and what to pick
You're just starting PrEP for the first time
Start with oral generic TDF/FTC unless you have a specific reason not to. It's the cheapest, most-studied, best-covered option. You can always switch to an injectable later if daily adherence becomes a problem.
You keep missing doses
Switch to an injectable. Yeztugo if available in your plan, Apretude if not. Data from HPTN 083 showed Apretude was 69% more effective than daily PrEP in real-world use — not because oral PrEP doesn't work, but because adherence is easier with an injection.
You're traveling frequently or living nomadically
Yeztugo (twice-yearly) is the best fit — two visits a year means you can time them with your travel. Apretude works too but requires more coordination.
You have kidney or bone concerns
Skip TDF-based options. Descovy (oral TAF-based) is easier on kidneys and bones, as are both injectables. Talk to your provider about Descovy, Apretude, or Yeztugo.
You're cost-conscious and uninsured
Generic TDF/FTC through telehealth (MISTR) costs $0 and doesn't require insurance. This is typically the cheapest and fastest path. If you want injectable, Gilead's MAP covers Yeztugo free for uninsured patients under 500% FPL.
You're a cisgender woman at risk through vaginal sex
Generic TDF/FTC or Truvada (oral), Apretude, or Yeztugo. Not Descovy — it isn't FDA-approved for this route of exposure. See PrEP for Women in 2026.
You're pregnant or breastfeeding
Generic TDF/FTC (or Truvada) has the largest safety database during pregnancy and breastfeeding. CDC, WHO, and ACOG all endorse continuing PrEP during pregnancy when at risk.

Start the Eligibility Tool →Can you switch between oral and injectable?
Yes. Switching from oral to injectable is straightforward — your provider will schedule your first injection after your current oral regimen. Going the other direction (injectable to oral) is also doable, but you'll need to start oral PrEP before your injectable tail fully decays, to avoid a gap in protection. Your provider will time this.
The answer most people should hear
If you're new to PrEP, pick oral generic TDF/FTC. It's cheap, it works, and it's easy to switch if something changes. If you've been on oral PrEP and daily adherence is becoming a burden, switch to Yeztugo or Apretude — you don't have to earn your way to injectables, and the choice is entirely about fit.
The goal is to be on some form of PrEP if you're at risk. Whichever option gets you there reliably is the right one.
