Airport Security & Customs Screening Procedure
Medication and medical devices such as melatonin 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.

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.
