PEP Treatment in Phuket: Emergency HIV Prevention, Walk In 24/7
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Takecare Clinic Phuket. Last reviewed: September 2026.
“PEP visits in Phuket tend to happen in the early morning, after a night in Patong or a condom that failed, and people often arrive having spent hours searching online and wondering whether they are overreacting. My answer is always the same: coming in is never an overreaction. The decision takes a few minutes with a doctor, and the only real mistake is waiting until the window has closed.” Dr. Ponlawat Pitsuwan
What PEP is and how it works
Post-exposure prophylaxis means taking antiretroviral medicines, the same class of drugs used to treat HIV, after a possible exposure. When HIV enters the body, it takes a short time to establish itself in immune cells. Antiretrovirals taken during that period can stop the virus from taking hold. That is why timing matters so much: the sooner PEP starts, the more effective it is, and after 72 hours it is no longer recommended because the chance of benefit is too low.
Current WHO guidance recommends a three-drug regimen, usually tenofovir with emtricitabine or lamivudine, plus dolutegravir, taken daily for a full 28-day course. The exact combination depends on your kidney function, other medicines and, if known, the source person’s HIV treatment history. PEP is highly effective when started early and taken fully, but it is not 100 percent, so follow-up testing is part of the plan.
Who should consider PEP
PEP is for people who are HIV-negative and have had a possible exposure, such as unprotected sex or a condom that broke, within the last 72 hours. The risk depends on the type of contact and the partner’s likely status. Receptive anal sex carries the highest sexual risk, followed by insertive anal and vaginal sex; oral sex carries a very low risk. A partner living with HIV who has an undetectable viral load on treatment does not pass HIV on through sex, so PEP is usually not needed in that situation if the viral load is confirmed.
| Situation within the last 72 hours | Usual recommendation |
|---|---|
| Condomless anal or vaginal sex, or condom broke, partner status unknown | Assess now; PEP often recommended |
| Condomless sex with a partner known to have HIV and a detectable or unknown viral load | PEP recommended |
| Sexual assault | PEP usually recommended, alongside wider care |
| Shared needles, or a needlestick from a used needle | Assess now; PEP often recommended |
| Oral sex only, or partner on treatment with a confirmed undetectable viral load | Usually not needed; discuss with the doctor |
| More than 72 hours since exposure | PEP not given; plan HIV and STI testing |
What happens at your PEP visit
You do not need an appointment. Tell reception you need PEP, and you will be seen promptly, with the conversation held in the privacy of a consultation room. The doctor asks when the exposure happened, what kind of contact it was and what you know about the other person. A baseline rapid HIV test confirms that you are HIV-negative before you start, because PEP is not a treatment for an existing infection. Baseline blood tests usually include kidney function and hepatitis B, and a pregnancy test where relevant. Because the same exposure can transmit other infections, we offer STD testing in Phuket at the same visit and discuss emergency contraception if you could become pregnant.
If PEP is recommended, you take the first dose in the clinic before you leave, from our on-site pharmacy, and go home with a supply and written instructions. Take the tablets at the same time every day, with or without food. If you miss a dose, take it as soon as you remember unless it is almost time for the next one.
Modern PEP regimens are well tolerated. The most common side effects are nausea, tiredness, headache and loose stools in the first week, and they usually settle. Tell us if you develop a rash, yellowing of the eyes, severe abdominal pain or vomiting that stops you keeping tablets down.
Follow-up testing after PEP
An HIV test is repeated about 4 to 6 weeks after the exposure and again at around 12 weeks (3 months), using a fourth-generation test. Syphilis and hepatitis testing may also be repeated, and a full screen for chlamydia and gonorrhoea (gonorrhea) is most reliable about 2 weeks after exposure. Use condoms until your follow-up tests are clear. Our guide to HIV testing in Phuket explains window periods and what a reactive result means.
PEP after sexual assault
If you have been sexually assaulted, you are not to blame, and you deserve care that is quick, private and on your terms. Your physical safety comes first. If you are injured or in danger, call 1669 for emergency medical help or the Thai police on 191.
Thai government hospitals run One Stop Crisis Centres (OSCC) that bring together medical care, forensic examination, counselling and support with reporting to the police. A forensic examination, which collects evidence that can be used later if you decide to report, is done at a hospital, and it is most useful as early as possible, ideally before washing or changing clothes. You do not have to decide about reporting straight away. Whether or not you report, you can come to any Takecare branch for PEP, emergency contraception, treatment to prevent some STIs and hepatitis B protection, and we can help you reach hospital services. Contact your embassy or consulate as well; they can support foreign visitors through the process.
When to see a doctor
Come in immediately, day or night, if you had a possible HIV exposure in the last 72 hours. Do not wait for the morning or for a regular clinic to open, and do not wait for symptoms, because there are none at this stage. While on PEP, come back the same day if you develop a rash, fever, yellow skin or eyes, or vomiting that stops you taking your doses.
A flu-like illness with fever, rash, sore throat and swollen glands 2 to 4 weeks after an exposure can be early HIV infection and needs an urgent test. Go to a hospital emergency department or call 1669 if you have serious injuries, heavy bleeding, or feel faint or confused, and use an emergency doctor in Phuket for urgent problems that are not life-threatening.
Prevention and early detection
PEP is an emergency measure, not a routine one. If you have needed PEP once and your risk is likely to continue, daily pre-exposure prophylaxis is a better long-term option; you can move straight from PEP to PrEP at the end of the 28 days if your HIV test is negative. Our PrEP clinic in Phuket explains how. Condoms remain the only method that also reduces the risk of other STIs.
Early detection matters because early HIV treatment protects your health and prevents onward transmission. Keep your follow-up test appointments even if you feel completely well.
Visiting Takecare Clinic in Phuket
Every branch is open 24 hours a day, every day, and PEP assessments are seen as a priority. Walk in to Takecare Clinic Bangtao (Cherngtalay), Takecare Clinic Kata-Karon or Takecare Clinic Patong, whichever is nearest.
You can message us on WhatsApp on your way, or call 081-718-9080. We confirm the price on WhatsApp before your visit. If you would rather not travel, a doctor can visit your hotel to assess you privately. We provide receipts and medical reports for insurance claims and offer direct billing with most travel insurers where the policy covers it.
Related services and treatments
If a test finds another infection, we treat it the same day where possible, including chlamydia treatment, treatment for genital herpes, and BV treatment for vaginal discharge that is not sexually transmitted. Lip blisters are usually a herpes virus too, and our cold sore treatment page explains how to avoid passing them on. For any other problem during your stay, a walk-in doctor in Phuket is available at every branch.
Summary
PEP is a 28-day course of HIV medicines that can prevent infection after a recent exposure. It must start within 72 hours and works best within 2 hours, so this is always a same-day visit. At Takecare Clinic Phuket we assess your risk, do a baseline HIV test, give your first dose and arrange follow-up testing at 4 to 6 weeks and 3 months, confidentially and at any hour.
“If you are reading this within 72 hours of an exposure, stop reading and come in. We can talk through the details while the first tablet is already working.” Dr. Ponlawat Pitsuwan
Frequently asked questions
How soon do I need to start PEP?
As soon as possible, ideally within 2 hours, and no later than 72 hours after the exposure. Every hour counts, because the medicines work by stopping HIV before it establishes itself in the body. After 72 hours PEP is not recommended, and the plan becomes HIV and STI testing at the right intervals instead.
Can I get PEP in Phuket at night without an appointment?
Yes. All three Takecare branches in Bangtao, Kata and Patong are open 24 hours a day and accept walk-ins. Tell reception you need PEP and you will be seen promptly by an English-speaking doctor. You can message us on WhatsApp on the way so we are ready for you.
What are the side effects of PEP?
Modern regimens are much better tolerated than older ones. Some people have nausea, tiredness, headache or loose stools in the first week, and these usually settle. Serious side effects are uncommon. Contact us if you develop a rash, yellow skin or eyes, severe tummy pain or vomiting that stops you taking your tablets.
How effective is PEP?
PEP greatly reduces the chance of HIV infection when started early and taken every day for the full 28 days, but no prevention method is 100 percent. Effectiveness falls the later it is started and if doses are missed. That is why follow-up HIV tests at 4 to 6 weeks and 3 months are part of every PEP plan.
Will my travel insurance cover PEP, and what does it cost?
Coverage varies between policies, and some exclude treatment related to sexual activity, so check yours. We confirm the price on WhatsApp before your visit, provide an itemised receipt and medical report for your claim, and offer direct billing with most travel insurers where PEP is covered. Do not delay starting PEP while you wait for an insurer’s answer.
I was sexually assaulted. Can Takecare help?
Yes. You can come to any branch for PEP, emergency contraception and treatment to prevent some infections, and we can help you reach hospital care. A forensic examination is done at a hospital One Stop Crisis Centre, ideally early. If you are in danger or injured, call 1669 or the police on 191. Reporting is your choice.
