Common questions

An over-the-counter nasal spray in a container over 100ml will be treated like any other liquid exceeding the limit and will be confiscated at the checkpoint. In practice, standard nasal spray bottles are 15–30ml, so this is rarely an issue. If you need a prescription spray in a larger quantity, declare it separately at screening with your prescription documentation.

Yes — all major aviation regions, including the US, UK, EU, Australia, and Canada, allow prescription nasal sprays in quantities exceeding 100ml when declared as medically necessary. You must present the original pharmacy packaging or a prescription to support the declaration. There are no regions that prohibit this medical exemption for nasal sprays.

At a US TSA checkpoint, tell the officer before your bag goes through the X-ray that you have a medically necessary liquid exceeding 100ml. Place the spray separately in a bin or in a clear bag so the screener can identify it easily. They may swab it for explosive trace detection, which is routine and takes under a minute. Your prescription label or a letter from your doctor confirms its medical status.

Pack your nasal spray in carry-on so it is accessible during the flight — cabin air is very dry and many people find a saline nasal spray useful mid-flight. OTC sprays under 100ml can go in your liquids bag with your other toiletries. Prescription sprays in larger sizes should be kept in an accessible outer pocket along with their documentation.
