Insulin on a Plane - Medication, Needles and Airport Security

How to travel with insulin: liquid-medicine exemption, needles, documentation and airport-security screening.

Carry-on baggageWITH RESTRICTIONS
Checked baggageYES

Short answer

Insulin is essential medication. Keep it in the cabin with the accessories and medical documentation you need; check any cooling equipment or battery-powered devices with the airline.

Carry-on baggage

Solid medicines are generally allowed in the cabin. Essential liquid medicines can be exempt from the standard 100 ml rule when needed during the journey.

Checked baggage

Medicines can generally also travel in checked baggage, but anything you may need during the journey is safer to keep with you.

Airport security

For liquid medication or medical equipment, security may ask for additional screening or evidence that the item is medically necessary.

Check your departure airport

General rules are not always enough. Liquid limits and screening procedures can differ by airport, so check the airport you are actually flying from.
