In opioid overdoses with bradycardia, what is the treatment dose?

Naloxone is the antidote for opioid overdose, reversing the effects at opioid receptors to restore ventilation and oxygen delivery, which in turn helps the bradycardia improve. Start with 0.4 mg IV naloxone and titrate every 2–3 minutes to see an improvement in respirations and consciousness; a common total dose is 0.4–2 mg, with higher amounts potentially needed for long-acting opioids while monitoring for re-sedation or withdrawal. If IV access isn’t available, intramuscular or intranasal routes can be used and titrated similarly. The key idea is that reversing the opioid effects with naloxone addresses the cause of hypoxia-driven bradycardia.
