  4. Naloxone dosing Q. For severe intoxication, what dosing would you order?

  5. Naloxone dosing Ans. Depends on how opioid dependent the pt is and how severe the respiratory depression. If R is very depressed, use 2.0 mg IV. If not that severe, use from 0.05-0.4 mg IV, using less for those pts who are opioid dependent. If pt doesn’t respond in 2 minutes, e.g., R improve And pupil size become normal, repeat. Still not adequate response, repeat q 5 minutes two times.
