A travel health kit is not a portable pharmacy. It is there to cover the gap between the moment something small goes wrong and the moment you can reasonably do something about it — the middle of a flight, a long day out, the first night in a new city, a Sunday morning.
Once you size it that way, the list gets shorter and more useful. For a city trip to Istanbul, where pharmacies are common and a duty rota covers nights and public holidays, a small pouch does the job. For a remote trip, the same categories apply but each one gets bigger.
Pack by category, not by brand
Six categories cover almost everything. What goes inside each one is whatever you already use safely at home, taken as directed on its packaging — this article names no products and no doses on purpose.
1. Your own treatment. Everything prescribed for you, in its original packaging, in hand luggage, with enough for the trip plus a margin. This is the part of the kit that is genuinely not replaceable, and it is covered properly in How to Travel With Prescription Medication.
2. Wound care. Plasters in a few sizes, a couple of sterile dressings, antiseptic wipes, a small roll of tape. Small cuts and grazes are the most common thing a kit actually gets opened for.
3. Stomach and hydration. A few sachets of oral rehydration salts take up almost no space and are the single most useful thing in the bag when a stomach upset arrives alongside a hot day. Add whatever you normally use at home for an upset stomach.
4. Everyday relief you already use. Pain and fever relief, an antihistamine, and anything else you would reach for at home — in travel quantities, not full boxes, and only things you have taken before without trouble.
5. Comfort items that prevent bigger problems. Blister plasters, high-factor sun protection, lip balm, insect repellent, and rehydration for the heat. In Istanbul these are not luxuries: the sightseeing is long, uphill and often in full sun.
Size the kit to the trip
- City trip, short stay: one pouch. You are never far from an *eczane*.
- Coast, islands or a long road trip: add more wound care, more rehydration salts and stronger sun protection, because the nearest pharmacy may be closed or an hour away.
- Travelling with children: add their own thermometer and their usual preparations in child-appropriate form, and keep everything out of reach in the room.
- An ongoing condition: the kit is secondary; the supply and the paperwork are the main event. See How to Prepare for International Travel With a Chronic Condition.
Pack the documents in the same pouch
The most under-rated kit item is paper. Keep with it: a copy of your prescription, your one-page medical summary, your insurance policy number and assistance line, and the emergency number 112. If somebody else ever opens your bag on your behalf, everything they need is in one place.
What not to pack
- Leftover antibiotics. Half a course saved from last winter is not a travel supply, and self-prescribing them causes more problems than it solves.
- Anyone else's prescription medicine. Not your partner's, not your parent's.
- Unlabelled tablets in a plastic bag or an unmarked organiser. If you cannot identify it, neither can anyone helping you.
- A full home medicine cabinet. Weight you will carry for two weeks to avoid a five-minute walk.
- Anything you have never taken before. A trip is a poor place to discover a reaction.
How to store it
Keep the kit in hand luggage on the way out, in one clearly recognisable pouch, and check the expiry dates once before you leave rather than once in the hotel room. Heat degrades things faster than people expect — the windowsill in an Istanbul August is not storage. Sharp items such as scissors follow the airline's cabin rules, so check before you pack them in the wrong bag.
The line the kit does not cross
A kit handles minor, self-limiting, familiar things. It does not diagnose, and it should not be used to talk yourself out of getting help. A fever that keeps climbing, pain that is getting worse instead of better, dehydration you cannot keep ahead of, a wound that looks infected or anything that frightens you is a reason to ask a professional rather than to open the pouch again.
And if it may be an emergency — chest pain, difficulty breathing, loss of consciousness, signs of stroke, a severe allergic reaction or heavy bleeding — the kit is irrelevant. Call 112.

Frequently Asked Questions
- How big does a travel health kit really need to be for a city trip?
- Small. In a city like Istanbul, pharmacies are easy to find and a duty rota covers nights and holidays, so the kit only has to cover the hours before you can reach one.
- What is the most useful thing in a travel kit?
- Rehydration salts and a thermometer, for most trips. One helps with the commonest travel problem, the other turns a vague feeling into information a clinician can use.
- Should I pack antibiotics just in case?
- No. Leftover or "just in case" antibiotics are a bad idea - the decision to use them depends on an assessment, and taking them wrongly can make a later diagnosis harder.
- Can I buy what I need in Istanbul instead of packing it?
- Most everyday items, yes, and pharmacies are widespread. But some products you buy freely at home require a prescription here, and brand names differ, so bring what you rely on.
- Does the kit go in hand luggage or hold luggage?
- Hand luggage for the essentials, especially your own prescription medicine. Scissors and similar items follow the airline's cabin rules.
- When should I stop treating something myself?
- When it is getting worse rather than better, when a fever will not settle, when you cannot keep fluids down, or when you are simply unsure - at that point the useful step is professional assessment.
