Motion sickness management permits up to 3 flights and requires accompaniment by an instructor pilot. Which option matches this rule?

• A. Scopolamine transdermal
• B. Dexedrine
• C. Promethazine/Ephedrine
• D. Metoclopramide

Answer: (C)

Motion sickness medications in aviation are regulated because they can affect performance, so some drugs are only allowed with supervision and for a limited number of flights. The option that matches the rule is promethazine with ephedrine. Promethazine helps prevent motion sickness, and ephedrine provides a mild stimulant effect to counteract drowsiness, helping maintain alertness during flight. This combination has historically been approved for use with up to three flights under the accompaniment of an instructor pilot, fitting the requirement you’re asked about. The other medications either don’t align with that supervised, limited-flight rule or aren’t used in this context for motion sickness: scopolamine is more likely to impair performance or carry stricter restrictions; dexedrine is a stimulant not used for motion sickness with this flight-rule framework; metoclopramide is an antiemetic without the specific three-flight supervision allowance.
