Not listed never means safe.
Seek help immediately if
- Unresponsive / can't be woken, even to a firm sternal rub
- Slow, shallow, or stopped breathing
- Pinpoint pupils
- Blue/grey lips, fingertips, or skin (cyanosis)
- Limp body; pale, clammy skin
- Choking or gurgling sounds ("death rattle")
- Slow, erratic, or absent pulse
What to do
- Try to wake them — shout their name, firm sternal rub
- Call emergency services immediately
- Administer naloxone if available
- Give rescue breaths (or CPR if there is no pulse)
- Place them in the recovery position
- Stay with them; re-dose naloxone every 2–3 minutes if there is no response
- Reversal agent
- Naloxone (Narcan) — opioid antagonist. May require repeated doses; its effect can wear off before the opioid does.
With prompt naloxone and rescue breathing, reversal is usually rapid. Because naloxone can wear off before the opioid — especially with long-acting opioids (methadone) or high-potency ones (fentanyl) — a period of monitoring is needed even after the person revives.
