Which medication should typically be avoided while flying?

Over-the-counter antihistamines are commonly advised against when flying due to their sedative effects. Many antihistamines, particularly the first-generation types, can cause drowsiness and impair cognitive function. This can significantly affect a pilot's ability to operate an aircraft safely, increasing the risk of impaired judgment, slower reaction times, and decreased situational awareness.

In addition to drowsiness, these medications can lead to other side effects such as dry mouth and blurred vision, further compromising a pilot's performance. The potential for these effects makes it crucial for pilots to avoid antihistamines before and during flight.

While other medications, like pain relievers and stomach remedies, may be safe in moderation and under the right circumstances, antihistamines carry a much higher risk of negatively impacting flight safety. Knowing the implications of taking such medication is an important part of a pilot's responsibility to ensure the safety of themselves and their passengers.
