Definition
In the IMSAFE self-assessment, medication refers to any prescription or over-the-counter drug a pilot has taken or is currently taking, considered for its potential to impair the mental or physical performance required to fly safely. The pilot must evaluate not only the underlying condition being treated but also the drug's possible side effects, including drowsiness, slowed reaction time, impaired judgment, dizziness, or visual disturbances, before acting as pilot in command.
Plain English
Any drug you've taken — prescription or off-the-shelf — that could affect how well you fly. Before flight, you check whether the drug (or the condition you're treating) might slow you down, cloud your thinking, or otherwise make you unsafe.
Context Anchor
Seen in the IMSAFE checklist, a personal preflight health check pilots use before deciding whether they are fit to fly.
Derivation
From the Latin medicari, meaning 'to heal' or 'to treat.' The aviation focus isn't on whether the drug heals — it's on whether the drug, or the illness behind it, makes the pilot unsafe to fly.
Why Pilots Care
Certain medications can cause drowsiness, slowed reaction time, or reduced decision-making ability, creating an immediate safety risk in the cockpit.
Intuition Check
Do not assume that a medication is safe for flying just because it is legal, prescribed, or sold without a prescription. In aviation, the question is whether it could affect your ability to fly safely.
Example Sentence 1

Example Sentence 2
