TSA (Transport Security Administration) har faktiskt en sida specifikt om inhalatorer :
Inhalers Carry On Bags: Yes (Special Instructions)
Checked Bags: Yes
TSA allows larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip, but you must declare them to TSA officers at the checkpoint for inspection.
We recommend, but do not require, that your medications be labeled to facilitate the security process.
