General guidance

Rule basis: General airport security guidance — rules can vary between airports and change over time. Confirm with your departure airport before you fly.

What to do: Pack to 100ml per container in a single 1-litre clear bag unless you've confirmed a larger allowance at both your departure airports.

Airline

Can this travel in cabin or checked baggage?

Cabin OK

Most airlines defer to airport security on liquids in the cabin.

Border

Can you bring this into the destination country?

Usually OK

Liquids themselves are rarely a customs issue — but contents (alcohol, dairy, CBD) might be.

Quick answer

Cabin only, exempt from 100ml, declared at screening, with prescription.

Once you've started a pen it's stable at room temperature (up to 30°C) for 56 days — no fridge needed in flight.

How to pack

  • Unopened pens: insulated bag with declared frozen cool packs
  • In-use pens: room temperature is fine, just keep out of direct sunlight
  • Always cabin baggage — hold temperatures can freeze and ruin the pen
  • Keep original box with pharmacy label and prescription

At security

Declare it at the start. Officers may inspect the pen, ask about your prescription, and occasionally vapour-test the cool pack. Don't put pens through the X-ray belt loose — keep them in the insulated bag and tell the officer first.

International notes

Allowed everywhere with prescription. UAE, Singapore and some Middle Eastern countries want a doctor's letter with the active ingredient (semaglutide/tirzepatide) named. Australia is strict about quantities — bring 3 months max.

FAQs

Can I put Ozempic in checked luggage?

Do I need a doctor's letter?

Strongly recommended, especially for international flights.

How do I keep it cold for long flights?

Declared frozen gel cool packs in an insulated wallet. Aim to keep it between 2–8°C.
