When administering naloxone, what is a common consideration for opioid-dependent patients?

• A. Withdrawal symptoms may occur
• B. No withdrawal risk
• C. It will always fully reverse overdose with no withdrawal
• D. It should be avoided

Answer: (A)

Naloxone reverses opioid overdoses by displacing opioids from mu receptors, but in patients who are opioid-dependent this abrupt blockade can precipitate withdrawal. When the body has adapted to the presence of opioids, stopping their receptor activity suddenly leads to agitation, sweating, yawning, rhinorrhea, nausea/vomiting, abdominal cramps, muscle aches, tremor, and sympathetic symptoms like tachycardia and hypertension. Because naloxone’s effects may wear off before the opioid is fully cleared, recurrent respiratory depression can occur, so patients often need repeat dosing and careful monitoring. This is a normal consideration and does not mean naloxone should be avoided; it simply requires anticipation of possible withdrawal and appropriate supportive care.
