A sensible first aid kit for Thailand is small: wound cleaner and dressings for coral cuts and scooter grazes, oral rehydration salts, a digital thermometer, insect repellent and sunscreen, plus copies of your prescriptions. Pharmacies are easy to find in Thai towns, so the kit is for the first hours and for places far from one, not a mobile pharmacy.
The US Centers for Disease Control and Prevention (CDC) tells travelers to Thailand to pack "a basic first aid kit", and publishes a packing list for the country. We used that list as the starting point and checked each item against Thai rules, because a few things on generic travel lists, such as some decongestants and sleeping pills, are controlled medicines in Thailand. This page is general information from official sources, not medical advice.

Wound care for coral cuts and scooter grazes
Small wounds are the most common reason to open a kit in Thailand. Reefs, rocks, boat ladders and the odd scooter spill all leave scrapes, and the CDC list covers them: antiseptic wound cleanser, antibacterial ointment, bandages in several sizes, gauze, adhesive tape, an elastic bandage for sprains, moleskin for blisters, scissors, tweezers and disposable gloves.
Seawater is the reason to take even a small cut seriously. The CDC warns that wound infections can follow contact between an open wound and salt or brackish water, caused by Vibrio bacteria, and that about one in five people with the most serious form die, sometimes within a day or two. People with diabetes, liver disease, cancer, HIV or thalassemia face a higher risk. If a wound that has been in the sea shows signs of infection, the CDC's advice is to seek care immediately. Our guide to coral cuts and sea urchin spines covers marine injuries in detail, and riders should read our page on safer scooter riding before renting one.
Check your tetanus protection before you go. The CDC recommends an adult booster every 10 years, and the UK's travel health service advises one if your last dose was more than 10 years ago and medical care may be hard to reach.
A bite or scratch from a dog or monkey is not a kit job. The CDC says to wash the wound with soap and clean water and go to a doctor right away. Rabies treatment cannot wait until you are home; what happens at the clinic is set out on our rabies and animal bites page.
Oral rehydration salts: the most useful sachet in the bag
Traveler's diarrhea is the illness most visitors meet. The World Health Organization treats it with oral rehydration solution, which replaces the water and salts lost in the stool, and the CDC notes that infants and young children are at greater risk of dehydration. A few sachets weigh almost nothing. Mix them exactly as the packet says, with safe water.
The CDC says ORS is "widely available at stores and pharmacies" in most low- and middle-income countries, so you can top up in Thailand. We could not confirm whether ORS is on Thailand's official household-remedy list, which decides where it may be sold, so bring your first sachets from home. Our guide to food poisoning and diarrhea in Thailand covers when it is time to see a doctor.
A thermometer, and why fever matters here
A digital thermometer is on the CDC list, and in Thailand it earns its place. Dengue fever is common in the country, and a reading gives a doctor something firm to work with. Our page on dengue fever lists the warning signs.
Malaria is the other reason. The UK Health Security Agency says that a fever of 38 °C or more more than a week after being in a malaria risk area, or any symptoms that could be malaria within a year of coming home, should lead to immediate medical care. Tell the doctor where you traveled.
Repellent, sunscreen and the marine park rule
The CDC list includes insect repellent, permethrin for clothing, anti-itch cream for bites, sunscreen of SPF 15 or more with UVA and UVB protection, aloe gel for sunburn, sunglasses and a wide-brimmed hat. Our article on avoiding mosquito bites covers repellents, and the guide to heat and sun in Thailand covers sunburn and heat illness.
Check the sunscreen label if you are going to the islands. Products with oxybenzone, octinoxate, 4-MBC or butylparaben are banned inside Thailand's marine national parks, with fines of up to 100,000 baht. The ban applies only in those parks, not on every beach; our page on the sunscreen ban lists the parks and explains how to read an ingredient list.
Sea stings are a separate case. Thailand's Department of Disease Control says to pour household vinegar on a jellyfish sting, never fresh water, and our guide to jellyfish in Thailand explains why.
What to leave at home: controlled medicines
Generic packing lists, the CDC's included, suggest a decongestant and a "mild sedative or other sleep aid". In Thailand that needs care. Pseudoephedrine, found in many cold and sinus tablets, is a controlled psychotropic, as are sleeping pills such as zolpidem, zopiclone and alprazolam: you may bring up to 30 days' supply with a doctor's certificate. Codeine in any strength, including combination painkillers and cough syrups, needs a permit from the Thai Food and Drug Administration.
Ordinary medicines are simpler. The Royal Thai Embassy in London says up to 30 days of prescribed use, in the original labeled containers, with a letter or prescription from your doctor. The CDC adds that syringes, needles and suture kits need a letter from your doctor on headed paper. Our guide to taking prescription medicine into Thailand explains the categories, the page on codeine and painkillers covers the painkiller trap, and the Thai FDA permit guide walks through the application.
Copy every prescription with its generic name. The CDC advises carrying copies of all prescriptions with generic names, not only brand names. Brands differ between countries, and a Thai pharmacist or doctor will recognize the generic name.
What to buy in Thailand instead
Pharmacies are common in Thai towns and malls, and the UK Foreign Office says hospitals and pharmacies across Thailand usually accept UK prescriptions. For how Thai pharmacies sell medicines, read our article on what you can buy over the counter, and the page on late-night pharmacies helps after dark. Buy from a proper pharmacy, because in the Foreign Office's words, street-sold medication "may not be genuine".
We have no official price data, so we do not claim that any item is cheaper in Thailand. Our suggestion is practical rather than financial: bring the things you need on day one or on a remote island, such as dressings, ORS, a thermometer and your own regular medicines, and buy bulky refills like sunscreen and repellent locally when they run out.
Papers and contacts that belong in the kit
The CDC lists documents alongside the plasters: your insurance card and claim forms, prescription copies, and a contact card with your accommodation, nearby hospitals and your embassy. Add the Thai ambulance number, 1669. Our guide to hospitals in Thailand explains how private and government hospitals work, and our packing list generator builds the rest of your bag. For clothes, shoes and luggage, see our article on what to pack for Thailand.
The CDC also suggests packing extras of important health supplies in case of travel delays, and learning basic first aid and CPR before you go.
When to stop using the kit and see a doctor
A kit is for small problems. Go to a doctor or hospital, and call 1669 in an emergency, if any of these happen:
- A bite or scratch from any animal, including a monkey or dog (CDC).
- A wound that has been in seawater and shows signs of infection (CDC).
- A sting from a stonefish, which the CDC says can be life-threatening.
- A fever of 38 °C or more after time in a malaria area (UKHSA), or the dengue warning signs on our dengue page.
- Diarrhea with blood or fever, which the CDC says should not be treated with anti-diarrhea tablets alone, or diarrhea in a baby or young child, who dehydrates faster.
Frequently asked questions
What should be in a first aid kit for Thailand?
Following the CDC's Thailand packing list: wound cleaner, antibacterial ointment, bandages and tape, tweezers, gloves, oral rehydration salts, a digital thermometer, anti-itch cream, insect repellent, sunscreen of SPF 15 or more, and copies of your prescriptions with generic names. Check any decongestant or sleeping pill against Thai rules first.
Can I bring cold and flu tablets to Thailand?
Check the ingredients. Pseudoephedrine, common in decongestants, is a controlled psychotropic in Thailand, allowed only up to 30 days' supply with a doctor's certificate. Codeine products need a Thai FDA permit. Plain products without these ingredients follow the ordinary 30-day rule for medicines.
Can I buy rehydration salts in Thailand?
The CDC says oral rehydration salts are widely available at stores and pharmacies in most low- and middle-income countries, which includes Thailand. We could not confirm their exact legal status in Thailand, so pack a few sachets for the first day and buy more at a pharmacy.
Is any sunscreen banned in Thailand?
Only sunscreens with oxybenzone, octinoxate, 4-MBC or butylparaben, and only inside marine national parks. Fines can reach 100,000 baht. Outside those parks the ban does not apply, but reef-safe products are a sensible choice anyway if you snorkel or dive.
