PEP cost on Koh Samui usually depends on four parts: the consultation, baseline tests, the 28-day medicines and follow-up testing. Across Thailand in 2026, complete private PEP packages we found in research typically range from about 3,500 to 9,000 THB, and island prices can sit at the higher end.
Prices change often, so treat every figure here as a typical market range, not a quote. For our own current price, message us and we will reply with what is included.
The one rule that beats any saving: PEP must be started within 72 hours, and the sooner the better. Never wait to compare prices if the clock is running.
Why PEP prices vary so much
When people search "how much is PEP in Thailand", they see very different numbers. That is mostly because providers bundle different things into the price.
What changes the price
- Which medicines are used. Generic versions usually cost less than original brands. A doctor will choose a suitable regimen for you.
- Which tests are included. Some prices cover only an HIV test, others add kidney, liver, hepatitis B and syphilis checks.
- Follow-up. Some packages include follow-up HIV tests and doctor messages, others charge for each one.
- Location and hours. Island clinics, evenings and weekends can cost more than a weekday visit in a big city.
PEP cost breakdown (typical 2026 ranges)
The table below splits PEP into its usual parts. The ranges come from prices published by private clinics and hospitals in Thailand during our 2026 research. They are not our prices, and they change.
PEP cost breakdown on Koh Samui and in Thailand (typical 2026 ranges)
| Part of PEP | What it covers | Typical range (THB) |
|---|---|---|
| Doctor consultation | Risk assessment, choosing if PEP is right, advice | About 500–1,000 |
| Baseline HIV test | 4th-generation test before starting | About 500–1,500 |
| Extra baseline blood tests | Kidney, liver, hepatitis B, syphilis (as the doctor advises) | About 1,000–3,000 |
| 28-day PEP medicines | The full course, generic or original | About 2,300–7,000+ |
| Follow-up HIV tests | Around 4–6 weeks and around 3 months | About 600–1,500 each |
Add the lines together and you can see why a "PEP 28 days cost" search gives such a wide spread. A low headline price may cover only the medicines.

Private clinic vs public hospital
Both can provide PEP in Thailand. The right choice depends on time, language and what matters most to you.
Private clinic vs public hospital for PEP
| Private clinic | Public hospital | |
|---|---|---|
| Typical cost | Higher; packages often about 3,500–9,000 THB | Usually lower for Thai residents; foreigners often pay fees |
| Waiting time | Usually short, often same day | Can be several hours |
| Language | English commonly spoken | Varies |
| Privacy | Small, discreet settings | Busy shared waiting areas |
| Follow-up | Often by message or in the same package | Usually a new visit each time |
Is PEP free in Thailand?
Thailand has built HIV services into its universal health coverage, as UNAIDS describes in its report on Thailand's HIV response. Thai nationals may be able to get HIV prevention services at low or no cost through public providers. Visitors usually pay, and eligibility rules can change, so check directly.
What a PEP package should include
A fair PEP price is one where you know exactly what you are paying for. Use this checklist when you ask any provider.
PEP package checklist
| Item | Should it be included? | Why it matters |
|---|---|---|
| Doctor assessment | Yes | Decides if PEP is right for your exposure |
| Baseline HIV test | Yes | Needed before starting PEP |
| Full 28-day supply | Yes, or clear pricing for the rest | Stopping early can reduce protection |
| Written treatment summary | Strongly recommended | Useful for your home doctor or insurer |
| Follow-up HIV testing plan | Yes | Tests around 4–6 weeks and 3 months |
| Side-effect support | Strongly recommended | Help if you feel unwell mid-course |
The World Health Organization's 2024 update on access to HIV post-exposure prophylaxis stresses starting as soon as possible, ideally within 24 hours. A package that gets you started quickly is worth more than a small saving that costs you a day.
Is PEP covered by travel insurance?
Sometimes. Some travel insurance policies pay for emergency medical care that includes PEP, while others exclude sexual-health care or set a high excess.
How to check quickly
- Look for "emergency medical expenses" and any sexual-health exclusions in your policy.
- Call or message the insurer's assistance line. You do not have to share more detail than they need.
- Keep every receipt and ask the clinic for a written treatment summary.
- Pay first if needed, then claim. Do not delay PEP while waiting for an insurer.
PEP cost on Koh Samui: local tips
On the island, the real cost is often time. A ferry, a long hospital queue or a closed clinic can eat into the 72-hour window.
- Message first. A quick WhatsApp message tells you the price and what is included before you travel across the island.
- Ask about the full course. If you are flying home, check you can take the whole 28-day supply with you. Our guide on how to keep taking your 28-day PEP course while you travel explains the rest.
- Ask what follow-up costs. Our follow-up support service can help you plan testing on Samui or at home.
- Budget for transport. A taxi across the island or a boat from a nearby island adds to the total, so factor it in when comparing options.
If you are not sure whether you need PEP at all, start with our step-by-step plan for the first 72 hours after a condom breaks.
Spending money on PEP more than once?
If you have needed PEP before, PrEP may cost less over time and protect you before any exposure. Compare the two in our guide on how PEP compares with PrEP and condoms, or see our HIV PrEP service on Koh Samui.
