What should I carry when travelling with insulin or medical devices in China?

At a glance

• Diabetes UK recommends taking 2–3 times the usual medication and equipment supply for a trip to cover disruption, with prescriptions and manual backup equipment where relevant. [1]
• It recommends a medical letter identifying the condition, medicines and devices, and keeping insulin and essential device supplies in hand luggage. [1]
• Insulin must not freeze; the guidance advises keeping it cool and separated from frozen cooling blocks. Use the storage limits for your actual product. [1]
• Security guidance differs by device. Diabetes UK directs travellers to the manufacturer's instructions for pumps and glucose sensors and discusses alternative screening where a scanner is unsuitable. [1]

What to do next

1. Before booking a complicated journey, review the route with your diabetes team. Arrange extra supplies, a written illness/device-failure plan and advice for the actual time zones, flight schedule and activity level; do not improvise a dose change from a general travel article.
2. Obtain a medical letter and recent prescription naming the medicine and device. Ask the airline about any required form, medical-liquid handling or device approval, and confirm China's import requirements for the exact medication through the appropriate official route if needed.
3. Read the manufacturer's travel and screening instructions for the exact model. Save them offline with the letter, and ask airport or airline assistance how to arrange appropriate inspection when the device should not go through a particular scanner.
4. Pack the essential supply and backups in cabin baggage you can retain if a larger bag is gate-checked. Protect medicines from temperature extremes and keep the prescribed treatment for low glucose accessible throughout transfers and meals.
5. Confirm suitable storage with the hotel before arrival. Use a monitored arrangement that meets the product instructions rather than assuming any minibar is suitable; keep insulin away from a freezer compartment or direct contact with frozen packs.
6. On arrival, follow the agreed time-zone and device-clock plan and know where to obtain medical help or replacement supplies. Keep the generic medicine name, concentration, device model and prescription available if you need local care.

If your situation is different

You use a pump or continuous glucose monitor: bring spare supplies and the manual fallback plan agreed with your team. Confirm model-specific screening and battery instructions rather than applying another device's rules.

You use insulin pens without a pump: protect the pen and spare insulin according to the manufacturer's temperature limits and keep the prescription available. Plan the actual dosing schedule with your clinician when crossing time zones.

Your hotel cannot provide suitable storage: arrange an appropriate cooling solution before staying there or choose a property that can support the requirement. Do not leave the medication in a parked vehicle or unmonitored freezing compartment.

A device fails or supplies are damaged: use the prescribed backup plan and contact medical support promptly. Tell the clinician the exact medicine, concentration and device rather than accepting a superficially similar substitute without review.

Common mistakes

• Putting all insulin in checked baggage: retain essential supplies in cabin baggage.
• Cooling insulin directly against frozen blocks: avoid freezing and use the product's storage instructions.
• Assuming every sensor has the same scanner rule: check the exact manufacturer's model guidance.
• Changing insulin timing from a generic internet example: arrange a personal plan before the trip.
