Correct answer: C — Contact the prescriber or recommend an appropriate regular laxative regimen alongside opioid treatment

Tolerance does not usually develop to opioid constipation and prophylaxis is often needed. 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.
