Final answer:
Yes, flight personnel who are not pilots can purchase over-the-counter drugs, but they should consult with a healthcare provider to ensure safety and proper job performance.
Step-by-step explanation:
Flight personnel who are not pilots, such as flight attendants, can purchase over-the-counter drugs. However, they should be aware of the potential effects these medications might have on their ability to perform their duties. The Federal Aviation Administration (FAA) does have guidelines about the use of medications for pilots and while these are more strict, flight crew members must also consider how these medicines might impact their job performance and safety. It is recommended that they consult with a healthcare provider, especially since they operate in an environment where they need to be alert and able to respond to emergencies.
