Fentanyl dosing should be adjusted for age, with a reduced dose for patients over 65 years.

• A. Increase to 50 mcg
• B. Use 25 mcg only for ages under 65
• C. Reduce to 25 mcg
• D. Do not adjust for age

Answer: (C)

Age-related changes in how the body handles opioids make older patients more sensitive to fentanyl and slower to clear it. This increases the risk of respiratory depression, sedation, and other adverse effects if the standard dose is used. Because of that, a lower starting dose is safer and more appropriate for patients over 65. Reducing to 25 mcg and then titrating to effect while closely monitoring breathing and airway status provides analgesia with less risk. Options that raise or keep the full 50 mcg dose in older patients increase the chance of adverse effects, and not adjusting for age ignores these pharmacologic changes.
