Medical Item Guidelines on United Airlines
49 CFR § 1544.219 — TSA Medical Regulations
The TSA operates under 49 CFR § 1544.219 guidelines permitting medically necessary liquids, gels, and aerosols in reasonable quantities exceeding standard 3.4 oz limits. While prescription labels matching your photo ID are not strictly legally required by federal law, carrying original labeled pharmacy packaging drastically reduces checkpoint screening friction.
Security Checkpoint Screening Procedure
Medication and medical devices such as first aid kit receive special consideration from TSA security personnel. Inform the officer at the start of the screening belt if you are carrying prescription drugs, liquid pharmaceuticals, or specialized equipment. Medical items are not required to fit inside a 3-1-1 liquids bag. Officers may visually inspect the containers, test for trace explosives, or ask you to open non-sterile outer packaging while ensuring your medical items remain sanitary.

Prescription medications including first aid kit are exempt from the 3-1-1 rule — carry them in their original labelled pharmacy container where possible.

Keep essential medications in your carry-on, never in checked luggage, to ensure access if bags are delayed or lost.
Medical devices, sharps, and syringes require a medical certificate; notify the TSA officer before screening begins.
Pack a sufficient supply for the entire trip plus extra days to cover potential travel disruptions or missed connections.
