Correct answer: A — Take it with plenty of water while upright and avoid lying down soon after the dose

Doxycycline can cause oesophageal irritation and administration counselling reduces risk. 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.
