✅ Find out whether malaria tablets are recommended.
✅ Buy comprehensive travel insurance.

1. Book a Travel Health Consultation Before You Travel
Booking a travel health consultation is one of the first steps to preparing for international travel.
A travel health consultation is an appointment with a qualified travel health professional who reviews your destination, planned activities, medical history and vaccination record to recommend any vaccinations, medicines or health precautions before you travel.
For most destinations, it’s best to book your appointment 6 to 8 weeks before departure. This allows enough time for travel vaccinations to become effective and for medicines, such as malaria tablets, to be started if needed.
You should consider booking a travel health consultation if you:
- Are travelling outside Europe
- Are visiting a country where travel vaccinations are recommended
- Are travelling to a malaria-risk area
- Are backpacking or travelling for several weeks
- Are visiting rural or remote locations
- Are pregnant or planning a pregnancy
- Are travelling with babies or young children
- Have a long-term medical condition, such as diabetes or heart disease
- Take regular prescription medicines
Every destination has different health risks, so personalised advice can help you prepare for your trip with confidence.
2. Check Which Travel Vaccinations You Need
The travel vaccinations you need depend on where you’re travelling, how long you’ll be away, the activities you plan to do and your medical history.
Some vaccines are recommended to reduce your risk of infection, while others may be required before you’re allowed to enter certain countries.
Common travel vaccinations include:
- Hepatitis A
- Hepatitis B
- Typhoid
- Yellow Fever
- Rabies
- Japanese Encephalitis
- Cholera
- Tick-borne Encephalitis
- Meningococcal vaccines
Some countries also require proof of Yellow Fever vaccination before entry.
Even if your destination doesn’t require additional travel vaccines, it’s important to check that your routine UK vaccinations are up to date, including:
- MMR (Measles, Mumps and Rubella)
- Tetanus
- Diphtheria
- Polio
Remember: A popular holiday destination doesn’t always mean there are no health risks. Vaccine recommendations can vary depending on where you’re staying, how long you’re travelling and the activities you plan to do.
3. Check Whether You Need Malaria Prevention
If you’re travelling to a country where malaria is present, protecting yourself from mosquito bites is an important part of your travel plans.
Malaria is a mosquito-borne infectious disease that can cause serious illness if left untreated. The risk varies depending on the country, region and time of year.
Your travel health adviser may recommend:
- Prescription malaria tablets
- Insect repellent containing up to 50% DEET
- Wearing long-sleeved clothing after sunset
- Sleeping under insecticide-treated mosquito nets
- Staying in air-conditioned or screened accommodation where available
Not every traveller needs malaria tablets. The most suitable option depends on your destination, medical history and the length of your stay.
Some malaria medicines need to be started before you travel, so don’t leave this until the last week before departure.
4. Prepare Your Prescription Medicines Before You Travel
If you take regular medication, preparing it properly is just as important as packing your passport.
Running out of medicine overseas or carrying it incorrectly can cause unnecessary stress and may interrupt your treatment.
Before you travel:
- Order repeat prescriptions in plenty of time.
- Pack enough medication for your entire trip, plus extra in case of delays.
- Keep medicines in their original labelled packaging.
- Carry essential medicines in your hand luggage whenever possible.
- Take a copy of your prescription or a GP letter if required.
- Check whether your medicines are restricted in the country you’re visiting.
- Plan how you’ll keep medicines at the correct temperature if refrigeration is needed.
Some countries have strict rules for controlled drugs, injectable medicines and certain prescription medications. Checking these requirements before you travel can help avoid delays at customs and ensure you have the medicines you need throughout your trip.
5. Carry the Right Medical Documents
Having the right medical documents can save time and reduce stress if you need healthcare while you’re abroad.
Before you travel, make sure you carry:
- Your travel insurance policy and emergency contact number
- A copy of your prescription if you take regular medication
- A GP letter if you’re travelling with controlled drugs, injectable medicines or medical equipment
- Your vaccination record if your destination requires it
- A Yellow Fever Vaccination Certificate where applicable
- Emergency contact details for a family member or friend
It’s also a good idea to keep digital copies of these documents on your phone or in secure cloud storage. If your originals are lost or stolen, you’ll still be able to access important information.
6. Buy Comprehensive Travel Insurance
Travel insurance is an essential part of preparing for international travel.
Even a minor illness or injury abroad can result in unexpected medical costs. A good travel insurance policy helps protect you financially if something doesn’t go to plan.
When comparing policies, check that your cover includes:
- Emergency medical treatment
- Hospital admission
- Emergency medical evacuation and repatriation
- Trip cancellation or disruption
- Lost or delayed baggage
- Cover for any planned activities, such as skiing, scuba diving or trekking
- Cover for pre-existing medical conditions if applicable
If you’re travelling to Europe, you may also be eligible to use a Global Health Insurance Card (GHIC) or a valid European Health Insurance Card (EHIC) to access some state healthcare services.
However, a GHIC or EHIC is not a replacement for travel insurance. It does not cover private healthcare, emergency repatriation or many other travel-related costs.
Before you buy a policy, always read the terms and conditions carefully so you understand what is and isn’t covered.
7. Pack a Travel Health Kit
Packing a small travel health kit can help you deal with common illnesses and minor injuries while you’re away.
What you pack will depend on your destination, the length of your trip and your personal health needs.
A basic travel health kit may include:
Item | Why You May Need It |
Prescription medicines | Continue your regular treatment |
Pain relief | Headaches, fever or minor aches |
Antihistamines | Allergies and insect bites |
Oral rehydration salts | Help prevent dehydration from diarrhoea |
Anti-diarrhoea medicine | Short-term symptom relief when appropriate |
Plasters and dressings | Minor cuts and blisters |
Antiseptic wipes or cream | Clean small wounds |
Thermometer | Monitor a fever |
Sunscreen (SPF 30+) | Protect against sunburn |
Insect repellent | Help reduce mosquito and insect bites |
Hand sanitiser | Maintain good hand hygiene |
If you wear glasses or contact lenses, consider packing a spare pair in case they become damaged or lost during your trip.
8. Stay Healthy While You're Abroad
Simple precautions can help reduce your risk of illness while travelling.
Practise Good Hand Hygiene
Wash your hands regularly with soap and water. If handwashing facilities aren’t available, use an alcohol-based hand sanitiser.
Be Careful With Food and Drinking Water
In some destinations, contaminated food or water can increase the risk of stomach illnesses.
To reduce your risk:
- Eat freshly cooked food where possible.
- Drink safe bottled or treated water if recommended.
- Avoid food that has been left uncovered for long periods.
- Wash or peel fruit before eating if appropriate.
Protect Yourself From Insect Bites
Mosquitoes and other insects can spread diseases such as malaria, dengue and Zika.
To help protect yourself:
- Apply insect repellent regularly.
- Wear long sleeves and trousers during the evening where appropriate.
- Sleep in air-conditioned or screened accommodation when possible.
- Use insecticide-treated mosquito nets if recommended.
Protect Yourself From the Sun
Spending long periods in the sun can increase the risk of dehydration, sunburn and heat-related illness.
Remember to:
- Apply sunscreen regularly.
- Wear a hat and UV-protective sunglasses.
- Drink plenty of water throughout the day.
- Stay in the shade during the hottest part of the afternoon.
Keep Up to Date With Local Health Advice
Health risks can change quickly.
Before and during your trip, check for updates on:
- Disease outbreaks
- Food and water safety
- Air quality
- Extreme weather
- Local healthcare services
Staying informed helps you make safer decisions throughout your journey.
9. Know What to Do After You Return Home
Most people return home without any health problems. However, some travel-related illnesses may not develop until several days or even weeks after you’ve returned to the UK.
Seek medical advice if you experience:
- A fever after visiting a malaria-risk area
- Persistent diarrhoea
- Severe stomach pain
- Blood in your stool
- An unusual skin rash
- Yellowing of the skin or eyes (jaundice)
- Difficulty breathing
- Symptoms that continue or become worse after your return
Always tell your GP or healthcare professional which countries you’ve recently visited. Your travel history can help identify the cause of your symptoms and support appropriate treatment.

Frequently Asked Questions
How many weeks before international travel should I book a travel health consultation?
It’s recommended to book a travel health consultation 6 to 8 weeks before you travel. This allows enough time for any recommended travel vaccinations to become effective and for medicines, such as malaria tablets, to be started if needed.
Do I need travel vaccinations for every country?
No. The vaccinations you need depend on your destination, the length of your stay, your planned activities and your medical history. Some countries don’t require additional vaccinations, while others recommend or require specific vaccines before entry.
How do I know which travel vaccinations I need?
A travel health consultation reviews your destination, travel plans, medical history and vaccination record to recommend any vaccinations or preventive medicines that may be appropriate for your trip.
Can I take prescription medicines abroad?
Yes. You should carry medicines in their original labelled packaging and check whether they’re restricted in the country you’re visiting. Taking a copy of your prescription or a GP letter may also help if you’re travelling with certain medicines.
Should I pack prescription medicines in my hand luggage?
Yes. Essential medicines should usually be carried in your hand luggage. This means you’ll still have access to them if your checked baggage is delayed or lost.
What should I include in a travel health kit?
A basic travel health kit may include:
Prescription medicines
Pain relief
Antihistamines
Oral rehydration salts
Anti-diarrhoea medicine

Pack items that are suitable for your destination and your own healthcare needs.
Is a GHIC enough when travelling abroad?
No. A Global Health Insurance Card (GHIC) or valid EHIC may provide access to some state healthcare services in certain countries, but it doesn’t replace comprehensive travel insurance and won’t cover every medical expense.
How do I know if I need malaria tablets?
Whether you need malaria tablets depends on your destination, your travel itinerary and the time of year you’re travelling. A travel health consultation can advise whether malaria prevention is recommended for your trip.
What should I do if I become ill after returning to the UK?
If you develop a fever, persistent diarrhoea, a rash or any unusual symptoms after travelling, seek medical advice as soon as possible. Always tell your healthcare professional which countries you’ve recently visited, as this can help with diagnosis and treatment.
Can I book a travel health consultation if I’m travelling at short notice?
Yes. Although it’s usually recommended to book 6–8 weeks before travel, a consultation can still provide useful advice, vaccinations and medicines even if you’re travelling sooner. The recommendations will depend on your destination and the time remaining before departure.
Why Book a Travel Health Consultation Before You Travel?
