01What is PrEP?

A daily habit that keeps HIV out.

PrEP (pre-exposure prophylaxis) is medicine for HIV-negative people. Taken before a possible exposure, it stops the virus from taking hold in the body.

The World Health Organization recommends it for anyone with a higher chance of HIV, whatever their gender or sexuality. That includes people with partners whose status they don’t know, people who don’t always use condoms, and anyone who has needed PEP before.

Exposed in the last 72 hours? PrEP can’t treat an exposure that has already happened. You need PEP, as soon as possible. Get PEP help

Is PrEP right for me?

Five quick questions to see whether PrEP could suit you. Your answers stay on your device and are never sent to us.

  • Anonymous, nothing is stored
  • A doctor makes the final call
Question 1 of 5 Could you have been exposed to HIV in the last 72 hours?

For example, a condom broke or you had sex without one.

Question 2 of 5 In the last 6 months, have you had anal or vaginal sex without a condom?
Question 3 of 5 Do you have a partner whose HIV status you don’t know, or who has HIV and isn’t on effective treatment?
Question 4 of 5 In the last 6 months, have you had an STI or needed PEP?
Question 5 of 5 Do you inject drugs and share needles or equipment?

This check gives general guidance only and is not a diagnosis.

Ask on LINE
01What is PrEP?

PrEP (pre-exposure prophylaxis) is medicine taken by HIV-negative people to prevent HIV. The most common form is a single tablet containing tenofovir and emtricitabine, taken every day or, for some people, “on demand” around sex (2-1-1).

02How well does PrEP work?

Taken as prescribed, PrEP reduces the risk of getting HIV from sex by about 99%, and from injecting drugs by at least 74% (US CDC). Most PrEP failures happen when doses are missed, so a routine that fits your life matters.

03How soon does PrEP start protecting me?

With daily PrEP, the CDC says protection is highest after about 7 days for receptive anal sex and about 21 days for receptive vaginal sex and injecting drug use. With on-demand 2-1-1, the double dose must be taken 2–24 hours before sex. Your doctor will confirm what applies to you.

04Can I start PrEP on the same day?

Usually, yes. You need a negative HIV test first, which takes about 20 minutes. Kidney and hepatitis B tests are done at the same visit. If you may have been exposed to HIV in the last 72 hours, you need PEP first, not PrEP.

05What tests do I need?

Before starting: an HIV test, a kidney function test and a hepatitis B test, plus STI screening where it makes sense. While on PrEP, you have an HIV test and check-up about every 3 months, and a kidney test from time to time.

06Does PrEP have side effects?

Most people have none. Some get mild nausea, headache or an upset stomach in the first weeks, which usually settles within a month. Kidney function is monitored because tenofovir can affect it in a small number of people.

07Does PrEP protect against other STIs?

No. PrEP only prevents HIV. Condoms help protect against other STIs such as syphilis, gonorrhoea and chlamydia, and the 3-monthly check-ups on PrEP catch STIs early.

08I’m visiting Bangkok. Can I get PrEP here?

Yes. Travellers and expats are welcome, and our doctors speak English. Tell us how long you are staying and we will talk you through the supply you need and a plan for continuing PrEP at home.

09Is my visit confidential?

Yes. You can register with a first name or nickname, and your results are never shared with employers, embassies or insurers.
