Why should a remote pilot be cautious about flying after taking a common antihistamine for allergies?
- A.Many antihistamines cause drowsiness and slowed thinking, even when labeled for daytime use
- B.Antihistamines make the control link unreliable
- C.Antihistamines are only a concern for passengers, not operators
Correct answer
A. Many antihistamines cause drowsiness and slowed thinking, even when labeled for daytime use
Why
Sedating antihistamines are a frequent hidden impairment because they are bought without a prescription and feel harmless. If a medication can cause drowsiness, its effect must be known and gone before flying.
