👁️ Eye Drops

Standard over-the-counter eye drops in containers over 100ml will be subject to the liquids rule and would need to be surrendered unless declared as medically necessary. However, most OTC eye drop bottles are 5–30ml — well under the limit — so this is rarely a practical issue. Prescription drops are medically exempt and can exceed 100ml if you carry documentation.

All major regions — including the US, UK, EU, Canada, and Australia — allow prescription eye drops in quantities exceeding 100ml as a medical necessity. The key requirement everywhere is that you carry the original pharmacy packaging or a doctor's letter. There are no regional differences in how prescription drops are treated.

For prescription drops, explain they are medically prescribed and present the original pharmacy label or prescription packaging. For OTC drops, simply confirm the bottle size is under 100ml. If your prescription drops are in a larger container, keep your doctor's letter or prescription readily accessible to avoid any delay.

Pack any eye drops you might need during the flight in your carry-on rather than checked baggage — the low-humidity cabin environment can make them useful mid-flight. Keep prescription drops in original packaging in an accessible part of your bag so you can reach them without unpacking everything at security.
