Correct answer: CStand up slowly and seek prescriber review because symptomatic postural hypotension may need dose review

Alpha-blockers can cause postural hypotension, particularly after dose changes. 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.
