When taking Ventolin on a plane there are several considerations:
You need to put your inhaler in a resealable clear plastic bag, along with any liquids under 100ml.
It’s best to keep your inhaler in your hand luggage as any other luggage could go missing and it’s a good idea to have access to Ventolin in case you need it during the flight.
It is a good idea to take a copy of your prescription or a letter from your doctor to confirm which medications you are travelling with. This is because some countries may have different laws about medications and you may be checked at customs.
