Is the airport liquid ban Europe-wide?
Essential medicines are an exception, and you can take enough supply for the duration of the trip the trip here meaning the length of your holiday, rather than just the flight – providing that you can prove that they are essential. A letter from your doctor will suffice. You should mention this to your airline when you book, or at least 24 hours before you fly. As a reminder, “liquids” here includes all drinks, water, soup, syrups, creams, lotions, oils, perfumes, mascara, sprays and pressurized containers (including shaving foam and spray deodorants), toothpaste, and gel. Liquid baby food or sterilized water, sufficient for the length of the flight, can also be taken through airport security. The accompanying adult will be required to prove this by tasting it at security.
