TSA Rules · Updated October 4, 2026
Can You Bring an Inhaler on a Plane?
Yes, always in your carry-on. Inhalers are essential medication with no size limit and no prescription requirement. Never pack a rescue inhaler in a checked bag.

Before the checkpoint
Three calls that matter
A rescue inhaler is a life-safety item. It must be reachable in the cabin, not in a bag under the plane.
TSA does not require a label or prescription for inhalers, though keeping the box can speed questions.
A spare inhaler or nebulizer over 3.4oz is fine; just mention it during screening.
