Correct answer: D — A regular stimulant laxative with or without a stool softener is usually needed

Opioids commonly cause constipation and tolerance to this effect is limited. Prophylactic laxatives are usually prescribed when regular opioid therapy is started. Patients should also be counselled about nausea, drowsiness, safe storage and breakthrough dosing.
