Opioid Overdose Management

Initial Treatment

Administer naloxone with an initial dose of 0.04-0.4 mg IV, and titrate the dose according to response, in patients with suspected opioid overdose, as recommended by the American Heart Association 1, 2
Start with low doses (0.04-0.4 mg) in patients with suspected opioid dependence to avoid precipitating severe withdrawal, with signs of acute withdrawal syndrome including hypertension, tachycardia, piloerection, vomiting, agitation, and drug cravings, as noted by the American Heart Association 1, 3, 4
Initial dose recommendations for naloxone administration are:
Administer naloxone via IV/IO, IM, or intranasal routes, with IV/IO or IM routes preferred for rapid response, as recommended by the American Heart Association 1, 3, 5, 4, 2

Monitor for non-cardiogenic pulmonary edema, a potential complication of naloxone administration or opioid toxicity, as noted by the American Heart Association 1
Be aware of the risk of acute withdrawal syndrome, pulmonary complications, and co-ingestions, which can increase mortality risk, and take steps to minimize these risks, including monitoring for non-cardiogenic pulmonary edema and aspiration pneumonia, as recommended by the American Heart Association 3, 6, 2
Assess for underlying mental health conditions, such as depression, and evaluate for previous suicide attempts, as recommended by the American Psychiatric Association 7
Evaluate for co-ingestions, particularly alcohol or benzodiazepines, which can increase overdose risk, and assess for underlying hepatic or renal dysfunction, which can impair opioid clearance, as noted by the American College of Physicians 7

Perform a comprehensive toxicology screen (urine and blood), basic metabolic panel, liver function tests, ECG, and chest X-ray to assess the patient's condition, particularly in cases of suspected opioid overdose, as recommended by the American College of Physicians 7
Monitor patients for at least 2 hours after the last naloxone dose, as suggested by the American Gastroenterological Association 8
Extended observation (12-24 hours) is required for long-acting opioid overdose, and patients should be monitored for at least 4-6 hours after the last naloxone dose, with monitoring of vital signs, level of consciousness, and respiratory status to detect potential complications, as recommended by the American Heart Association 3, 6, 2

Refer patients who respond to naloxone to advanced healthcare services due to the risk of recurrent respiratory depression, as advised by the American Heart Association 1
Connect patients to addiction treatment services after acute management and consider prescribing take-home naloxone for high-risk individuals, as recommended by the American Heart Association and the American College of Cardiology 2
Educate patients and families about overdose recognition and response, and train lay rescuers in opioid overdose response, including naloxone administration, as recommended by the American Heart Association 1, 5, 2
Training potential witnesses of overdose in recognition and response, and providing first aid training in responding to opioid overdose, is also recommended by the American Heart Association 5, 2

If no pulse and no normal breathing, begin high-quality CPR immediately, activate emergency response system, get AED and emergency equipment, and consider naloxone administration after CPR initiation if opioid overdose is suspected, as recommended by the American Heart Association 9
If pulse present but no normal breathing or only gasping, administer naloxone immediately, provide rescue breathing, and monitor until emergency responders arrive, as recommended by the American Heart Association 9
Follow the response algorithm, which includes checking for responsiveness, calling emergency services immediately, administering naloxone if available, positioning the person on their side, beginning CPR if not breathing normally, and administering additional naloxone doses if no response after 2-3 minutes, as recommended by the American Heart Association 2
