What is the maximum single dose of fentanyl?

• A. 200 mcg
• B. 100 mcg
• C. 150 mcg
• D. 300 mcg

Answer: (B)

Fentanyl’s extreme potency means the margin between effective analgesia and dangerous respiratory depression is very small. Because of that, clinicians use a fixed, conservative cap for a single administration to provide pain relief while keeping the risk of breathing problems low. This cap is set so that a normal, rapid IV bolus can be given with close monitoring, and without pushing the patient into apnea or chest wall rigidity. When more analgesia is needed, it’s safer to titrate with additional small doses rather than pushing a larger amount in one go. Doses above that single-dose cap carry a substantially higher risk and are not appropriate as a single administration. Always tailor dosing to the patient’s status, route, and clinical context, and adjust with careful monitoring.
