What is a common side effect of opioid analgesics?

The chosen answer is correct because constipation is a well-documented and common side effect of opioid analgesics. Opioids work by binding to specific receptors in the brain and the gastrointestinal tract, which can lead to decreased motility in the intestines. This slowdown in gut movement can result in hardening of stools and difficulty in passing them, contributing to constipation.

While nausea, dizziness, and insomnia can also occur with opioid use, they are not as universally experienced as constipation. Opioid-induced constipation is a particular concern in clinical settings, and healthcare providers often take preventive measures to manage it in patients receiving opioid therapy. Thus, recognizing constipation as a common side effect highlights the importance of monitoring patients and implementing appropriate interventions.
