Health & Medicines in Thailand: Essential Travel Tips

Which health products should you bring to Thailand?

Good preparation starts with packing the right items. Think of:

• Sunscreen with a high SPF (at least 30), waterproof and reef-friendly. Note: sunscreens in Thailand often contain whitening agents because many locals prefer not to tan.
• Insect repellent with DEET. You can bring this from home, but it’s also available in every 7-Eleven in handy travel sizes. Plus, they often smell nice too! This helps prevent mosquito bites and diseases like dengue.
• Afterbite or soothing gel for insect or mosquito bites.
• Hand sanitizer, especially useful when you’re on the go.
• Band-aids and wound care supplies: treat small cuts or blisters immediately.

Which medicines are useful for your Thailand trip?

Besides basic health products, it’s best to bring some medicines with you:

• Paracetamol or ibuprofen for pain and fever.
• Medication for diarrhea, such as ORS (oral rehydration salts) and possibly loperamide.
• Allergy medicine Antihistamines are also available in Thailand, though they may not be the brands you’re used to. They can help if you have a strong reaction to mosquito bites and develop large bumps. For example, Zyrtec is an antihistamine brand widely available in many drugstores in Thailand.
• Any personal medications you take daily, always in the original packaging with a doctor’s note and a copy of your prescription.
• Are you prone to seasickness or motion sickness? At 7-Eleven, you can buy special pills in packs of two to help reduce nausea and dizziness while traveling.
• First aid kit

Do you need a First Aid Kit?

You can bring a few essentials like plasters, paracetamol, diarrhea pills and tweezers, but you don’t need to carry a full first aid kit unless you plan to spend several days trekking through the jungle. Most basic items are inexpensive and easy to find at 7-Eleven.

Important tips about medication and health in Thailand

• Medication and customs rules: Some medicines, like strong painkillers, sleeping pills, or ADHD meds, cannot be brought in without a doctor’s declaration. Always have this paperwork to avoid issues at customs.
• Storing medicines in heat: Tropical heat can reduce medication effectiveness. Keep medicines in their original packaging and store them in a cool, dry place—like a cooler or special travel cooler bag if that is needed.
• Drinking water advice: Don’t drink tap water in Thailand. Always use bottled water for drinking. For ice cubes, choose those with a hole in the middle, as these factory-made ice cubes are safe to use and help avoid stomach problems.

Health Risks and Prevention in Tropical Environments

Thailand’s heat and humidity can easily cause heat exhaustion. In the hot season, temperatures can rise up to 40 degrees. It is important to recognize the signs and know how to act quickly to prevent or ease symptoms.

• Dizziness or weakness
• Cold, clammy skin
• Rapid, weak pulse
• Headache
• Nausea or vomiting
• Fatigue

If you notice these symptoms:

• Find a cool, shaded place immediately.
• Lie down and raise your legs to improve blood flow.
• Drink water or ORS slowly to prevent dehydration.
• Avoid heavy exertion until you feel better.

Additional tips to prevent heat exhaustion:

1. Stay hydrated
   Drink plenty of water throughout the day, especially if you are outdoors or active. Avoid excessive alcohol or caffeinated drinks, as they can dehydrate you.
2. Wear appropriate clothing
   Choose lightweight, loose-fitting, and light-colored clothing to help your body stay cool.
3. Use sun protection
   Wear a wide-brimmed hat, sunglasses, and sunscreen to protect yourself from direct sun exposure. You can also follow the example of locals by carrying a lightweight UV-protective umbrella. For example, near the Grand Palace, umbrellas are available to borrow for shade.
4. Avoid the hottest part of the day
   Limit outdoor activities during peak heat hours, typically between 11 a.m. and 4 p.m. Consider taking a dip in a pool, visiting an air-conditioned shopping mall, or having a siesta during this time.
5. Use cooling methods
   Use damp cloths, take cool showers, or use portable fans around your neck to help lower your body temperature.
6. Acclimate gradually
   If you are new to a hot climate, allow your body time to adjust by gradually increasing your exposure to heat over several days.

Can you eat at street food stalls in Thailand?

You can definitely eat at street food stalls in Thailand, but it’s important to take some precautions to avoid food poisoning:

• Choose stalls that are busy with locals; this is often a sign that the food is fresh and safe.
• Make sure the food is cooked thoroughly and served hot.
• Avoid raw or undercooked dishes.
• Check that the stall looks clean and that the vendors handle food hygienically (for example, with clean hands and covered food).
• Drink bottled water and avoid ice from unknown sources.

With these tips, you can safely enjoy the delicious Thai street food experience

What to do if you get food poisoning?

If you unfortunately get food poisoning, it’s really unfortunate. But most of the time, you will get better. Follow these two steps:

1. Rest and stay close to a toilet.
2. Drink plenty of fluids, preferably water or ORS (oral rehydration salts) to avoid dehydration.

Usually, you’ll feel better within three/four days. Want to recover faster? Visit a local pharmacy and explain your symptoms. They’ll often give you medicine for a few days that works quickly—often you’ll feel much better the next day.

At home, we prefer natural remedies, but on the road, it’s often harder. You want to recover as quickly as possible. If unsure, always see a doctor. Healthcare in Thailand is of good quality.
