Immediate interventions in the emergency management of an opioid overdose in a primary care setting include:

  • Assess and support airway, breathing, and circulation (the ABCs) to ensure the patient is stable and to prevent hypoxia.
  • Administer naloxone promptly, an opioid antagonist, to reverse the effects of opioid toxicity and restore adequate respiration.
  • Call emergency services immediately for advanced care and transport to hospital, as further monitoring and treatment may be required.
  • Provide basic life support including rescue breathing or cardiopulmonary resuscitation (CPR) if necessary until emergency help arrives.
  • Monitor the patient closely after naloxone administration, as opioid effects may recur due to naloxone’s shorter half-life compared to many opioids.

These steps are critical to prevent death and serious complications from opioid overdose in any setting, including primary care. While the provided NICE guidelines focus on opioid use and detoxification, the emergency management principles of opioid overdose are consistent with standard clinical practice and supported by UK clinical guidance on opioid toxicity management .
