What this means
Insulin and injectables are liquid medicines administered by needle or pen, most commonly insulin for diabetes but also other prescribed injectable treatments. They are generally allowed for personal medical use and are usually exempt from cabin liquid limits when declared, but should be carried in hand luggage with their needles and supporting documentation. You may need to declare them and show a prescription at security and customs.
What's included
- Insulin vials and pre-filled insulin pens
- Insulin pen needles and disposable syringes
- Glucagon emergency kits
- Other prescribed injectables (e.g. some GLP-1 medicines)

- Sharps disposal containers for used needles

Common types & examples
Insulin pens
Pre-filled disposable or refillable pens; keep with their needles and labeling.
Insulin vials and syringes
Vials with separate syringes; declare needles at screening.
Cooling storage
Gel packs and travel coolers are usually permitted to keep insulin cold.
GLP-1 and other injectables
Other prescribed injectable medicines follow similar carry-on and declaration rules.
Sharps and disposal
Used needles should be carried in a sharps container for safe disposal.
Why it's regulated
Injectables involve liquid medication and needles, so aviation security and customs require declaration to manage liquid limits, sharps safety, and confirmation that the medicine is for genuine personal medical use.
Typical allowance
Many countries treat injectable medicines as exempt from cabin liquid limits and allow a personal-use supply of roughly 30 to 90 days; thresholds and declaration rules vary by destination.
