We recommend that you keep all medication in your hand luggage and easily accessible.
If you suffer from any illness that needs to be treated with an injection (diabetes, etc.) or with liquid medication exceeding the 100 ml permitted, you will need a medical certificate to take the syringes, needles and necessary medication on board.
Remember, airport security services are beyond our control and you should therefore prepare a contingency plan with your doctor in advance in case the authorities don't let you board the plane with these items.
