Do I Need PrEP?
PrEP is a highly effective way to stay HIV-negative — but it isn’t for everyone. Whether it makes sense for you depends on your situation, not a label. Use the self-check below.
The honest answer
⚠️ Possible exposure in the last 72 hours?
If there’s any real chance of HIV exposure, PEP can prevent infection — but only if started early, ideally within hours and no later than 72 hours. Don’t wait to read on. Call now.
PrEP (pre-exposure prophylaxis) is medicine taken before possible exposure to prevent HIV — and taken correctly, it’s extremely effective. The real question isn’t “does PrEP work” (it does) but “is my situation one where the protection is worth it” — and that’s an individual call. Here’s an honest way to think it through.
Recent exposure rather than ongoing risk?
A 30-second confidential check — it will tell you whether your situation points to urgent PEP rather than PrEP. Your answers stay on the page.

You may benefit from PrEP if you answer YES to any of these
| If any of these is true… | …then |
|---|---|
| You have sex, more than rarely, with partners whose HIV status you don’t know | PrEP may help |
| You sometimes have condomless anal or vaginal sex | PrEP may help |
| A partner is HIV-positive and not confirmed undetectable | Discuss PrEP |
| You have needed PEP more than once | PrEP is likely better than repeat emergency PEP |
| You have had a recent STI | Suggests ongoing exposure risk |
| You meet casual or app-based partners whose status you can’t confirm | Consider PrEP |
Even a single “yes” is a good reason to have the conversation — it doesn’t commit you to anything.
Being honest cuts both ways
A good doctor will also tell you when PrEP is more than you need. You may not need it if:
- You’re in a mutually monogamous relationship where both partners have recently tested HIV-negative.
- Your partner is HIV-positive but has a consistently undetectable viral load on treatment — because U=U (undetectable = untransmittable) means they cannot pass HIV on sexually.
- You had a single low-risk exposure and are now outside the PEP window.
- You’re not currently sexually active, or have no realistic ongoing HIV exposure.
Tests we usually check first
PrEP is safe and simple, but a few baseline checks make it safe for you — and you must be confirmed HIV-negative before starting (starting PrEP while unknowingly HIV-positive can cause problems):
- HIV 4th-generation test (and an HIV RNA test if a recent exposure or symptoms suggest very early infection)
- Kidney function (serum creatinine / eGFR)
- Hepatitis B (HBsAg, anti-HBs, anti-HBc) — and hepatitis C where relevant
- STI screen as appropriate — syphilis, gonorrhoea, chlamydia (urine / oral / rectal sites as needed)
- Pregnancy test where relevant
Once on PrEP, follow-up is straightforward: a repeat HIV test roughly every 3 months with an adherence and STI check, plus periodic kidney monitoring depending on your age and baseline.
It isn’t instant
Daily oral PrEP needs time to build protective levels, and this differs by exposure type:
- Receptive anal sex: protection builds after about 7 days of daily use.
- Receptive vaginal sex and injection-drug exposure: maximum protective levels may take up to about 21 days.
- Exact timing for insertive sex is less well defined — your doctor will advise when you can rely on it.
An important safety note
PrEP can be taken daily, or in some cases as event-based (“2-1-1”) dosing around a planned exposure. But these are not interchangeable for everyone.
What it does and doesn’t protect against
This matters: PrEP prevents HIV — and only HIV. It does not protect against syphilis, gonorrhoea, chlamydia, herpes, HPV, hepatitis B or pregnancy. So even on PrEP, condoms, vaccination (HPV, hepatitis B) and periodic STI screening may still be needed. PrEP is one strong layer of protection, not the whole wall.
Decision points
- You answered “yes” to anything in the self-check above
- Your partner is HIV-positive (PrEP plus their treatment is very effective)
- You’re using PEP repeatedly — a sign PrEP may suit you better
- You want protection but aren’t sure which option fits your life
Dr. Manuj Sondhi — with a Tata Memorial fellowship in HIV — can assess your situation confidentially, arrange the baseline tests, and choose the option that fits you. (A possible exposure in the last 72 hours needs PEP now, not PrEP.)
