What must pilots do regarding medications before flying at altitude?

Pilots must consult with an Aviation Medical Examiner regarding medications before flying at altitude to ensure their safety and the safety of others. This consultation is crucial because certain medications can impair cognitive and physical functions, which are vital for operating an aircraft.

An Aviation Medical Examiner has the expertise to evaluate the potential effects of specific medications on a pilot’s ability to fly. They can provide guidance on which medications are acceptable and how they might affect flight performance. It is particularly important because regulations vary based on the type of medication, its dosage, and the individual pilot’s health status.

While increasing dosage, stopping all medication, or taking over-the-counter supplements might seem like alternatives, they don’t address the critical need for professional guidance to ensure aviation safety. Each of these actions could lead to adverse effects that might compromise the pilot's ability to fly safely. Hence, consulting with an Aviation Medical Examiner is the most responsible and necessary action before flying.
