Answer
Scopolamine (Hyoscine) is the appropriate choice — a centrally acting antimuscarinic with well-established efficacy for motion sickness via its action on the vestibular system and vomiting centre. Cetirizine, a second-generation antihistamine with poor blood-brain-barrier penetration, lacks the central antimuscarinic/antihistaminic action motion sickness prophylaxis requires — sedating first-generation antihistamines or scopolamine are needed for this specific indication.
