Asthma Inhalers
Allowed
Metered-dose inhalers are exempt from the 100ml limit but should be declared if metallic.
Quick answer
Respiratory attacks need immediate relief, so airlines treat inhalers as essential medical devices. Keep at least one inhaler on your personâseat pocket or jacketânot buried in an overhead bin.
Metered-dose inhalers (MDIs) are pressurised; security may swab them but rarely confiscates. Nebulizers with liquid medicines need a doctor letter because they carry more than 100ml of solution.
Cabin humidity is low and can trigger symptoms. Drink water regularly, avoid heavy perfumes, and notify crew if you anticipate needing a nebulizer plug point (available only on limited aircraft).
Pre-trip prep
- âCheck canister levels; replace if less than 30% remaining.
- âPack a spare inhaler and spacer in a labelled pouch.
- âCarry prescription or asthma action plan if using steroid inhalers requiring documentation.
In-flight routine
- âKeep inhaler within armâs reach for take-off and landing.
- âInform cabin crew before using a nebulizer so they can assist with power needs.
- âHydrate frequently; dry air aggravates airways.
