Correct answer: B — Advise prompt prescriber review because montelukast can cause neuropsychiatric adverse effects
Sleep and mood changes are recognised montelukast adverse effects requiring review. In this scenario, the pharmacist should prioritise safe supply, appropriate counselling and timely referral or clarification where needed. This is the single best answer because the other options would either delay assessment, ignore a clinically significant risk, or create an unsafe legal or professional outcome.
