Keep the medicines you need with you in the cabin, in their original labelled packaging. Before packing, check each active ingredient against the rules of every destination and transit country. A security allowance, a prescription and permission to import a medicine are three different things.
This guide helps you prepare questions, documents and a bag arrangement. Your prescriber or pharmacist must confirm the treatment and storage plan; the relevant authorities determine what you may bring. Sources checked September 10, 2026.
Start while there is time to obtain documents
Arrange a travel health appointment at least 4–6 weeks before departure, as recommended by the CDC medicine travel guide. Check permit processing times even earlier when booking. If departure is sooner, contact your clinician and the relevant authority now; do not assume a last-minute application will be accepted.
Bring your itinerary and medicine list to that conversation. Discuss the supply for your stay, a suitable allowance for delays within import limits, and a written plan for time zones and missed doses. Do not change a dose or dosing interval based on this packing guide.
Run these checks for each medicine
Use the active ingredient, strength, dosage form and total quantity, rather than only a brand name. Include over-the-counter products and supplements. Keep the answers with your travel documents; you do not need to enter personal medical information on this website.
| Check | What to establish before packing | If the answer is missing |
|---|---|---|
| Destination and transit | Is this ingredient permitted, restricted or prohibited? What quantity and paperwork apply on this route? | Ask the country's health/customs authority or embassy. A pharmacy receipt is not an import permit. |
| Documents | Original label; prescription or clinician letter; required translation, certificate or advance permission. | Use the destination's requested format. Do not assume a short generic letter is sufficient. |
| Supply | Trip quantity plus an agreed delay buffer, within the permitted total. | Ask your prescriber about a lawful alternative or local care arrangement. Do not hide excess supplies. |
| Storage | Exact product's temperature limits, unopened/in-use rules and usable period outside refrigeration. | Ask your pharmacist with the package in hand. An insulated pouch alone does not establish a safe temperature. |
| Flight and devices | Departure and connecting checkpoint procedures; airline arrangements; device manufacturer's scanner instructions. | Contact the airport, airline or manufacturer before travel. Keep any written instructions accessible. |
The Canadian government's medication guidance is a useful starting checklist, including original packaging and destination checks. It does not replace the destination's own rules. If an ingredient is prohibited, discuss an alternative with your clinician before travel; do not stop prescribed treatment on your own.
Two examples of why a prescription is not enough
Japan: ordinary import procedures and controlled medicines differ
Japan's Ministry of Health, Labour and Welfare calls the document Import Confirmation (Yunyu Kakunin-sho). Its ordinary personal-use exemptions include up to one month's supply of prescription medicine and up to two months for other medicines, subject to the listed categories and exceptions. Larger amounts normally require Import Confirmation obtained before leaving home.
Those quantity exemptions do not authorise prohibited or controlled ingredients. Narcotics and stimulant raw materials have separate advance-permission requirements, and some drugs cannot be brought in. Check the exact ingredient and device/injection category through the ministry's linked guidance. A one-month trip is not automatic permission to bring every prescription.
Schengen: check your residence and route
The Article 75 certificate rules concern residents of a Schengen state travelling to another Schengen state with prescribed narcotic or psychotropic medicines. A certificate is issued or authenticated by the competent authority, is valid for at most 30 days, and is separate for each such medicine.
If you live outside Schengen, travel longer, or cross a non-Schengen border, ask each relevant destination authority which documents apply. Do not assume this certificate covers every visitor to Europe. Germany's official certification guidance explains its process.
Choose a pouch that stays with you
Put your labelled medicines, supporting paperwork and needed supplies in an accessible cabin pouch. If your cabin suitcase is taken for gate checking, remove the medicine pouch first. Keep it in the personal bag you retain. Check the airline's arrangements for extra medical baggage in advance instead of assuming a free additional bag.
Do not make checked luggage your backup medicine supply. A delayed bag defeats that plan, and the storage conditions may be unsuitable. For theft or loss, plan access to local medical care and keep a separate copy of your medicine list and contacts. Do not hand another traveller your medicines without checking the applicable personal-import rules.
Separate identification from organisation: a pill organiser can be convenient, but it does not replace the labelled packaging or required documents. Keep medical records securely accessible offline rather than relying only on mobile data or email access.
Insulin: use the exact product's storage instructions
The CDC's diabetes travel advice says to keep insulin out of checked baggage and away from direct sunlight, hot cars and direct contact with ice. Protect supplies from both heat and excessive cold.
There is no single 28-day rule for all insulin pens. For example, Novo Nordisk's US product storage tables list 28 days below 86°F (30°C) after first use for NovoLog FlexPen, but 56 days for Tresiba U-100/U-200 FlexTouch at that room-temperature limit. In-use refrigeration instructions also differ. These are examples showing why the exact product and presentation matter, not a storage plan for another insulin.
Before travel, ask the pharmacist to write down your product's limits and discard date, including time already spent out of the refrigerator. Plan the whole journey: transport to the airport, connections, hotel storage and day trips. Ask how to monitor temperature and what to do after an excursion outside the allowed range. Do not put medicine directly against frozen packs or a hotel refrigerator's freezing compartment.
Security checks are separate from border permission
For US checkpoints, the TSA item guidance allows medically necessary liquids, gels and aerosols above the usual limit in reasonable quantities for the trip; declare them for inspection. This is a US screening rule, not worldwide permission to import the medicine.
Check each departure and transfer airport's procedure for medicine, cooling packs and injection supplies. Inform the officer about an attached pump or glucose monitor before screening, and follow the exact device manufacturer's guidance. Arrange an alternative inspection where needed; do not disconnect a treatment device merely because a general packing article says to do so. Keep needles safely capped and packaged for handling.
Before leaving home
Tick each item after checking it. This checklist is temporary and does not save answers.
If medicine is lost, delayed or temperature-damaged
Use your pre-agreed care plan and contact a local licensed clinician or pharmacist promptly. Your travel insurer's assistance service or embassy may help locate care; they cannot guarantee a replacement medicine or acceptability of a foreign prescription. If missing treatment may put you in immediate danger, seek urgent medical care instead of waiting for luggage. Do not double a later dose or substitute an unfamiliar product without professional advice.
Common packing questions
Can I bring one month's supply to every country?
No. Limits depend on the ingredient, destination, route and documentation. Even a short supply can need advance permission or be prohibited. Check before obtaining and packing the travel quantity.
Does approval at security mean the medicine is legal abroad?
No. Security screening and import permission are separate checks. Complete both for your itinerary, including relevant transit points.
Should spare insulin go in a checked bag?
Keep insulin in the cabin with you, including the spare supply, and follow its product-specific storage conditions. Remove the medicine pouch if your cabin suitcase is gate-checked.
Does TripPack decide which medicines I need?
No. This guide helps organise travel checks. Your clinician decides your treatment and suitable travel supplies; authorities decide import permission. The general packing generator does not validate medicines or permits.
