PrEP and HIV Prevention: What You Need to Know
HIV prevention has been transformed in the last decade — and a huge part of that transformation is PrEP. If you've been putting off learning about it, this guide is for you. It's simpler than you think.
The Basics
PrEP (Pre-Exposure Prophylaxis) is medication that prevents HIV before exposure. Take it consistently, and the risk of getting HIV from sex drops by about 99%. It's one of the most effective preventive measures in modern medicine.
Two main forms:
- Daily pill (Truvada, Descovy, generics): one pill a day, simple and proven
- Injectable (Apretude): every two months, increasingly popular
Who Should Take It
If you answer yes to any of these, PrEP is worth discussing with a provider:
- You're a man who has sex with men and don't always use condoms
- You have a partner living with HIV (even an undetectable one — extra layer)
- You've had an STI in the last year
- You don't know your partner's HIV status and don't always use condoms
- You inject drugs or share equipment
PrEP isn't a judgment on your behavior — it's a tool for people who want protection that works even when condoms don't.
How to Get It
- Ask any doctor or clinic. PrEP is a standard prescription.
- LGBTQ+ health centers and Planned Parenthood offer it on informed consent — no therapist letters needed.
- Telehealth (US): Folx Health, Plume, Q Care Plus — all online, discreet.
- UK: Free via NHS sexual health clinics (like 56 Dean Street in London).
- Many places subsidize it: in the US, most insurance covers it, and patient assistance programs exist for the uninsured. In much of Europe, it's free.
The Routine
- HIV test before starting, then every 3 months while on it (standard clinic practice)
- Kidney function monitoring (simple blood test) — usually yearly
- Most people have zero or mild side effects (initial nausea passes within weeks)
What PrEP Doesn't Do
- It doesn't prevent other STIs — syphilis, gonorrhea, chlamydia are still a real risk. Regular STI testing is still essential.
- It doesn't prevent pregnancy.
- It doesn't work if you don't take it — consistency is everything.
The Other Half of the Story: U=U
PrEP protects HIV-negative people. For HIV-positive people, the revolution is U=U: Undetectable = Untransmittable. A person living with HIV on effective treatment — with an undetectable viral load — cannot pass the virus to sexual partners. Zero transmissions across thousands of studied couples.
This changes everything: HIV-positive people on treatment are not a threat, and their status alone is no reason for fear or rejection.
The Stigma Problem
HIV stigma still causes real harm: people avoid testing, avoid treatment, and avoid relationships out of fear. The truth is that HIV today — caught early and treated — is a manageable condition. People with HIV live full, long, healthy lives, and they cannot transmit the virus when undetectable.
The Bottom Line
- Get tested regularly — it's normal, smart, and usually free
- If you're eligible, consider PrEP — it's safe, effective, and widely available
- If you're living with HIV, get treated — undetectable means healthy and safe
- Treat people living with HIV with dignity, not fear
Prevention is community care. Every person on PrEP or treatment is a link in a chain that ends the epidemic. Be a link.
