Correct answer: E — Constipation is common and a regular stimulant laxative should be considered

Opioid-induced constipation is common and does not usually improve with tolerance. Prophylactic laxative therapy is often needed unless contraindicated. The patient should not reduce analgesic dosing independently or use antidiarrhoeal medicines for prevention.
