A private travel planner and a practical guide

Travelling With HS

Travel interrupts the routine that makes HS manageable at home: wound care, clothing, medicines, washing and the familiar route to your practice. This guide helps you think it through before you leave.

What has to come with you, what should stay reachable and what to settle beforehand — assembled from your own answers.

With HS, travel is mostly a logistics problem

Heat, sweating, a lot of walking, long periods sitting, friction from clothing or luggage, drainage away from home, carrying enough dressings, taking medicines through airport security, storage on the way, replacements abroad, what your insurance covers: each of those questions has an answer — the answers just normally live in very different places.

This guide brings them together and turns them into preparation with a deadline: five minutes before the trip instead of ten separate searches the night before.

No account required. Your answers stay in your browser.

The travel guide

Why travel interrupts the routine rather than changing the condition

People who have lived with HS for a while usually have a routine: particular dressings, a place where the supplies are kept, a pharmacy that stocks the usual things, clothing that works over the affected areas, a familiar route to the practice. That routine is the reason much of everyday life stays manageable.

A trip removes almost all of those conditions at once — for a limited period that is known in advance. That is precisely why it can be planned. The point is not to manage the condition differently, but to let your own routine travel with you.

So these pages do not tell you whether you should travel, and they predict nothing about how you will be while you are away. They help with the preparation.

Pack in two layers

Checked luggage can be delayed or lost. That is the practical reason for the most important decision in this guide: what you might need during the journey itself belongs in the bag you can always reach — subject to the rules of the transport you are using.

The reachable layer typically holds the medicines for the journey, enough wound-care supplies for the trip and a possible delay, one change of clothing, small disposal bags, documentation for your medicines and contact details. Guidance for travellers with chronic illnesses recommends exactly this: required medicines and necessary supplies in carry-on baggage.

The rest goes in the main luggage — in a quantity you set yourself. Nobody knows that number better than you: the planner does arithmetic on the numbers you enter and sets no buffer on your behalf.

Heat, walking and friction

Dermatology patient guidance recommends reducing overheating and sweating where these aggravate HS, and avoiding clothing that causes friction. Travel often brings both together at once: warmer weather, more walking, a bag carried all day, less choice about changing.

No promise follows from that. There is no evidence that a packing list, a clothing choice or a particular way of travelling prevents flares, and this guide claims that nowhere. What can be planned is the shape of the day, the breaks, the chance to change, and whether the clothing that works at home also fits what the trip involves.

Carrying medicines

When flying from an EU airport, the standard limit for liquids in cabin baggage is 100 ml per container. Medicines needed during the trip are exempt from that volume limit, though you may be asked to establish that they are genuine medical items. Individual airports with newer screening equipment now apply different rules — so what your departure airport says takes precedence.

A separate question is what the destination country allows. Airport security does not decide that. Medicines covered by narcotics legislation need additional, authenticated certificates depending on the destination; sort that out with the prescribing practice in good time.

On storage requirements this guide deliberately states no numbers. They differ from product to product, and what applies is the product information for your medicine together with what your pharmacy or healthcare team tells you.

Prescriptions in another EU country

A prescription from one EU country is generally valid in other EU countries. The same medicine may, however, carry a different brand name there, or not be available. That is why the active substance is the decisive detail, not the brand name.

Besides the active substance, a cross-border prescription should carry your own details, the issue date, the prescriber with their professional qualification, contact details, work address and signature, plus the formulation, quantity, strength and dosage.

Healthcare abroad

The European Health Insurance Card gives access to medically necessary state-provided healthcare during a temporary stay in EU countries plus Iceland, Liechtenstein, Norway, Switzerland and the United Kingdom. For chronic conditions, care that is necessary during the stay can be covered — judged against the situation and the length of stay.

It is not travel insurance, though: private treatment, repatriation and lost property are not covered. And it does not mean every HS treatment is automatically covered — planned treatment abroad normally has to be arranged with your health insurer in advance.

What this guide cannot establish

There is very little research specific to travelling with HS. What is written here rests on two kinds of source: dermatology patient information about heat, sweating, friction and wound care — and official rules on aviation security, prescriptions and healthcare abroad.

Together they make for good preparation. Neither supports a statement about how you will be on this particular trip. Accounts from other people with HS in forums and social media show the questions are real — but they are lived experience, not medical evidence.

What these pages are not for

  • They do not predict flares and do not promise that preparation prevents one.
  • They do not assess whether you are fit to travel, and neither encourage nor discourage a trip.
  • They name no medicine, active substance, dressing, antiseptic or supplement, and change nothing about your treatment.
  • They keep no country-by-country list of import rules or emergency numbers — the destination country’s official bodies govern those.

Ready to work through the trip?

The planner asks only about practical characteristics of the journey — no account, no diagnosis details, no exact destination — and turns them into a checklist you can print, download as a PDF or copy.

Common questions

Does flying make HS worse?

There is no evidence for that, and this page does not claim it. What can be described are the practical circumstances of a flight: long periods sitting, warmth, limited bathroom access, and rules about what you may carry. Those circumstances can be planned for — that is not a prediction about your condition.

Does the planner predict whether I will have a flare while away?

No. It predicts nothing about the course of your condition, does not assess whether you are able to travel, and neither encourages nor discourages a trip. It builds a checklist from your own answers.

Does the 100 ml rule apply to my medicines?

Medicines you need during the trip are exempt from the volume limit for liquids in cabin baggage; you may however be asked to establish that they are genuine medical items. Some airports with newer screening equipment now apply different rules — so check your departure airport’s information before you travel.

How many dressings should I pack?

Nobody but you can answer that — it depends on what you already use. The planner multiplies the daily amount you enter by the number of days you enter and adds the buffer you choose yourself. Nothing is derived from your condition.

Is my prescription valid in another EU country?

A prescription issued in one EU country is generally valid in other EU countries. The medicine may be called something different there or be unavailable — which is why a cross-border prescription should name the active substance, not only the brand name.

Is the EHIC enough cover?

The EHIC gives access to medically necessary state-provided healthcare during temporary stays in EU countries plus Iceland, Liechtenstein, Norway, Switzerland and the United Kingdom. It is explicitly not travel insurance: private treatment, repatriation and lost property are not covered.

Where are my answers stored?

By default nowhere except in your browser’s memory while the page is open. Only if you explicitly choose “Save on this device” is the plan written to your browser’s local storage — never to a server of this website. “Delete my plan” removes it again immediately.

Can I open the checklist without an internet connection?

The plan is generated entirely in your browser and needs no connection once it exists. Whether the page itself reopens offline depends on your browser’s cache — the downloaded PDF and the printout are the reliably offline versions.

Evidence, travel rules and editorial review

There is very little research specific to travelling with HS. What is said here about heat, sweating, friction and wound care rests on dermatology patient information that describes exactly those points as self-care.

No prediction follows from that: there is no evidence that a packing list, a clothing choice or a particular way of travelling prevents flares. These pages claim that nowhere.

The statements about aviation security, prescriptions and healthcare abroad reproduce official rules from the European Union and German federal authorities. Rules of that kind change more often than medical fundamentals — so they are verified on their own, shorter cycle, and both dates are shown separately below.

In case of doubt, what governs is always the information from your departure airport, your airline, the destination country, your health insurer and your healthcare team.
