Where can you get PrEP in Bangkok? The best-known place for visitors is the Thai Red Cross Anonymous Clinic, run by the Thai Red Cross AIDS Research Centre on Ratchadamri Road in Pathum Wan. The clinic lists PrEP (pre-exposure prophylaxis, a daily or event-based HIV prevention medicine) among its services, alongside HIV testing, emergency PEP and sexual health checks. PrEP is also part of Thailand's national HIV prevention program, set out by the Department of Disease Control, and is provided through health services around the country.
This guide explains what PrEP is, what to expect at a first appointment, the options Thailand's national guidelines cover, and what to do if you need emergency protection instead. It is general health information, not medical advice; a clinician will tailor PrEP to you.
What PrEP is
PrEP is medicine taken by people who do not have HIV to lower their chance of getting it. The Thai Red Cross AIDS Research Centre describes it as an antiretroviral taken before a possible exposure, and notes that research clearly shows it prevents HIV infection. In Thailand the standard pills are combinations called TDF/FTC and TAF/FTC.
PrEP protects against HIV only. It does not prevent other sexually transmitted infections, which is why PrEP services include regular testing for those too.
The Thai Red Cross Anonymous Clinic
The Anonymous Clinic is part of the Thai Red Cross AIDS Research Centre, at 104 Ratchadamri Road in Pathum Wan, a short distance from Lumphini Park. The clinic's website lists these services:
- HIV testing, including self-test kits
- PrEP and emergency PEP
- testing and treatment for sexually transmitted infections
- hepatitis testing, and vaccines for hepatitis A and B, HPV and flu
- a clinic for transgender people
The clinic runs weekday sessions and some evening and Saturday sessions, and it offers online registration and consultation. Hours and fees change, so call the clinic on +66 2 251 6711 before you go. Bring your passport. The clinic publishes a fee schedule for its tests and services, so ask about costs when you book.
What to expect at a first PrEP visit
Thailand's national PrEP guidelines, published by the Department of Disease Control's Division of AIDS and STIs in 2025, set out a standard process. In broad terms:
- An HIV test first. You need a negative HIV test before starting, because PrEP is not a treatment for existing HIV. Staff will usually suggest screening for other STIs at the same visit.
- Other checks where needed. Hepatitis B screening is part of the process, and a kidney function test is done at the start for people aged 50 or over or with risk factors such as diabetes or high blood pressure.
- A plan for how to take it. Oral PrEP can be taken every day. The guidelines also allow an "on demand" schedule around a possible exposure for some people, but not for everyone; the right schedule depends on your circumstances and sex assigned at birth, so follow the clinician's instructions exactly.
- Follow-up. For oral PrEP, the guidelines schedule HIV tests at the start, after one month, and then every three months, with regular STI checks.
If you are staying for a short trip, ask the clinic how much medicine they can supply and whether you should continue with a provider at home; follow-up testing matters.
Injectable PrEP and newer options
The 2025 national guidelines also cover long-acting options: an injection of cabotegravir every two months (CAB-LA), and lenacapavir (LEN), an injection given every six months after a starting dose. According to the guidelines, oral TDF/FTC and TAF/FTC are covered by Thailand's national health insurance benefit package, CAB-LA is not, and lenacapavir was expected to become available in Thailand. The Department of Disease Control has since run training for pilot injectable PrEP services. Availability for visitors varies, so ask the clinic what it currently offers.
If you may have been exposed: PEP, not PrEP
If you think you were exposed to HIV in the last few days and are not already on PrEP, you need PEP (post-exposure prophylaxis) urgently, not PrEP. The Thai Red Cross AIDS Research Centre notes that PEP must be started within 72 hours of the exposure, and the sooner the better. Go to the Anonymous Clinic during its opening hours, or to a hospital emergency department at any other time.
Thai citizens and residents
For people covered by Thailand's national health insurance, oral PrEP is included in the benefit package managed by the National Health Security Office. Long-term residents with other insurance should check what their policy covers.

PrEP is a prescription medicine and should be started through a clinic, because you need a negative HIV test first and regular follow-up tests while you take it. Use a clinic such as the Thai Red Cross Anonymous Clinic rather than buying tablets without a prescription.

No. PrEP lowers the chance of getting HIV only, which is why PrEP services include regular testing for other sexually transmitted infections.
