The morning-after pill is sold over the counter in pharmacies in every Thai province and is also given at government hospitals, according to the UK Foreign Office. The type you are most likely to be offered has to be taken within 72 hours, and the sooner the better. For regular contraception, the safest plan is to bring your own supply from home, because we could not verify which pills Thai pharmacies sell or on what terms.
This page covers emergency contraception first, because that is the time-critical question, then the regular pill, condoms, and what to pack. How Thai pharmacies work in general, and why the law and practice sometimes differ, is covered in our article on what you can buy over the counter in Thai pharmacies. If you think you may already be pregnant, our page on traveling to Thailand while pregnant is the better starting point.

The morning-after pill: over the counter, but ask the pharmacist
The UK Government's guide for Thailand says emergency contraception is available over the counter in pharmacies in all provinces and at government hospitals. In practice, that means asking at the counter of an ordinary pharmacy, not a convenience store; there is no pharmacist at a 7-Eleven. We could not confirm the exact legal category the Thai Food and Drug Administration puts it in, so treat it as a medicine the pharmacist hands over and can advise on, rather than something you pick off a shelf.
Tell the pharmacist when the unprotected sex happened and about any other medicine you take. If it is late in the evening, our page on late-night pharmacies explains where to look; a hospital is the fallback when everything else is closed.
The time limit: 72 hours, and why sooner is better
The NHS describes two kinds of emergency pill and one device:
| Method | Time limit (NHS) | In Thailand |
|---|---|---|
| Levonorgestrel pill | Within 3 days (72 hours) | The type the UK guidance for Thailand describes |
| Ulipristal acetate pill | Within 5 days (120 hours) | We could not confirm it is sold in Thailand |
| Copper IUD (coil) | Within 5 days | Needs a doctor; availability for visitors not checked |
The UK Foreign Office's general advice says emergency pills work up to 72 hours "and in some cases up to 5 days". That longer window applies only to the ulipristal pill, which we found no evidence of on Thai pharmacy shelves, so plan around 72 hours. The NHS says the pills are more effective the sooner you take them, and that around 1 to 2 women in every 100 who take one still become pregnant. It calls the copper IUD the most effective type of emergency contraception.
Do not wait for the weekend to end. The 72 hours start at the time of unprotected sex, not when a clinic opens. If you are on an island on a Saturday night, go to the nearest pharmacy that is open, or to a hospital, rather than waiting for a better-stocked shop.
When a pharmacist or doctor should check first
The NHS says most people can take the emergency pill, including those who cannot use other hormonal contraception and those who are breastfeeding. It may not be suitable if you take steroid medicine for asthma or if you are overweight. Ask a doctor or pharmacist first if you take medicine for tuberculosis, epilepsy or HIV, or the antifungal griseofulvin or the herbal remedy St John's wort; the NHS says you may be advised to have an IUD fitted instead. In Thailand, an IUD means a hospital or clinic visit; our hospital guide explains how private and public hospitals work.
The morning-after pill does not protect against sexually transmitted infections. If the condom broke or was not used with a new partner, our page on sexual health and STI testing covers testing and PEP, the HIV medicine that also has a 72-hour limit. If the sex was not consensual, our guide to help after a sexual assault explains how hospitals can provide both medicines.
The regular pill: bring your own supply
We could not find an official source on which combined or progestogen-only pills are sold in Thailand, under which brand names, or whether a prescription is needed. Pharmacy staff may well find you an equivalent, but a different brand can mean a different hormone or dose, which is a conversation for a doctor, not a guess at the counter. The simple solution is to bring enough for the whole trip in the original packs; our article on packing for Thailand covers the rest of the bag.
Thailand's rules for ordinary prescription medicines, as given by the Royal Thai Embassy in London, allow up to 30 days of use, in original containers with proper labels, together with a letter or prescription from your doctor. Our guide to taking prescription medicine into Thailand explains the rule and what to do on longer stays.
The Thai Red Cross Anonymous Clinic in Bangkok, which many visitors use for sexual health, does not list contraception among its services, so it is not the place to go for a new supply.
Vomiting and diarrhea can stop the pill working
Stomach bugs are common on a Thai trip, and they matter if you take the pill. The NHS says that vomiting within 3 hours of taking a combined pill, or diarrhea lasting more than 24 hours, can mean the pill has not been absorbed, so you may need extra contraception such as condoms for a while. The exact steps depend on your pill; follow the NHS guidance or your pack leaflet, and ask a doctor if unsure. Our page on food poisoning and diarrhea in Thailand covers the illness itself.
Condoms
Condoms are sold in pharmacies and convenience stores across Thailand. The CDC's packing list for Thailand includes latex condoms, and the UK health service for travelers calls condoms the most effective way to prevent sexually transmitted infections with new or casual partners. If you have a latex allergy or prefer a particular type, bring your own, as we could not check the range on sale.
Frequently asked questions
Can you buy the morning-after pill over the counter in Thailand?
Yes. The UK Foreign Office says emergency contraception is available over the counter in pharmacies in all provinces and at government hospitals. Ask the pharmacist; convenience stores such as 7-Eleven have no pharmacist and are not the place to buy it.
How long after sex can I take the morning-after pill in Thailand?
Plan on 72 hours, and take it as soon as possible. The NHS says the common levonorgestrel pill works within 3 days; a 5-day pill exists, but we could not confirm it is sold in Thailand.
Do I need a prescription for birth control pills in Thailand?
We could not verify the rules or the brands on sale. Bring your own supply in the original packs with a prescription or doctor's letter, within Thailand's 30-day limit for ordinary medicines.
Does the morning-after pill protect against STIs?
No. Of the contraceptive methods, condoms are the one that also reduces the risk of sexually transmitted infections. If you are worried about HIV or another infection after sex, look into testing and PEP as soon as possible.
