Most people spend weeks planning where to eat, what to pack, and which excursions to book. But health prep rarely gets the same attention. A forgotten prescription or an undeclared medical condition on your insurance policy can turn a holiday into a headache fast. Here is the checklist worth working through before any trip abroad.
Book a Travel Health Appointment Early
Vaccinations
Some vaccination courses need more than one dose, given several weeks apart. This means you cannot leave it until the last minute. Requirements also change depending on where you are going. Some countries require proof of a yellow fever vaccination just to enter. Check what your specific destination requires rather than assuming a standard course is enough.
NHS vs Private Travel Clinics
Some travel vaccines are free on the NHS for certain destinations. Hepatitis A and typhoid are covered in some cases. Others, such as rabies or Japanese encephalitis, are usually only available through a private clinic. Private clinics often have faster appointment slots and offer a wider range of services. Try to book at least six to eight weeks before you travel.
Antimalarials
Not every destination requires antimalarials. But it is worth checking rather than guessing. The right option depends on your destination, how long you are staying, and your personal health. A GP or pharmacist can help you choose the right type and check for any interactions with other medications you take.
Check Your Prescriptions Are Up to Date
Glasses, Lenses and Medications
An eye test is one of the easiest things to put off. If it has been over a year since your last check, book one before you go. If your prescription has changed, you may need new glasses before you travel. The same applies to contact lenses . Sourcing your usual brand abroad is harder than it sounds, so stock up before you leave.
More importantly, check every regular medication you take against the length of your trip. Add a few extra days of supply as a buffer in case your return is delayed. GP repeat prescription requests are not always processed quickly, so make sure you leave enough time. It is also worth checking whether your medication is sold under the same name at your destination. Many drugs have different brand names in other countries.
Review Your Travel Insurance Medical Cover
Pre-Existing Conditions
This is where many travellers run into problems. If you do not declare a pre-existing condition when you buy your policy, your insurer can refuse to pay out if something goes wrong. This applies to conditions like asthma, diabetes, and mental health diagnoses. Declare everything at the point of purchase, even if it feels minor. If standard policies are not covering what you need, specialist insurers are available for more complex medical histories.
The GHIC Card
UK travellers visiting EU countries should apply for a Global Health Insurance Card before they go. It replaced the old EHIC card after Brexit. It gives you access to necessary treatment through state healthcare systems in Europe. However, it is not a replacement for travel insurance. It does not cover being flown home, private treatment, or anything beyond what the local state system offers its own residents.
What to Look for in a Policy
When you compare policies, pay close attention to the emergency medical treatment limit. Check whether prescription costs abroad are included. Make sure there is a 24 hour emergency assistance number you can call. A cheap policy that leaves out the most important cover is not worth buying.
Sort Your Medications Before You Leave
Keep all medications in their original packaging with the pharmacy label still on. Split your supply between your hand luggage and your main bag in case one gets lost. For longer trips or if you take controlled medications, ask your GP for a letter that explains what you are taking and why.
Some medications that are common in the UK are restricted or banned in other countries. Codeine, for example, is a controlled substance in parts of the Middle East and Asia. Check the rules for your destination on the Foreign, Commonwealth and Development Office website before you travel.
Take Care of Your Mental Wellbeing Too
Travel changes your routine more than most people expect. Shifts in sleep, diet, time zones, and daily habits can affect how you feel, especially on longer trips. If you know that flying or travel causes you real anxiety, speak to your GP before you go rather than trying to manage it on the day.
Small practical steps also help. Pack earplugs and a sleep mask for overnight flights. Have a rough idea of how you will stay active. Try not to let jet lag take over the first few days of your trip. These small things add up and make a real difference to how you feel when you arrive.
