Is any of this happening now?
Call 911
Call emergency services now if a person:
Cannot be awakened or is only briefly responsive
Has slow, shallow, irregular, or stopped breathing
Makes choking, gasping, snoring, or gurgling sounds
Has blue, grey, or unusually pale lips or skin
Collapses, has a seizure, or has no pulse
May have swallowed an opioid accidentally, especially if they are a child
If you are unsure whether opioids are involved, emergency responders can assess the person, and naloxone is unlikely to harm someone who has not taken an opioid.
Other emergency signs, for anyone
Someone who is struggling to breathe, gasping, choking, or cannot get words out
Someone who has chest pain, tightness or pressure lasting more than a few minutes
Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
Someone who is unconscious, or cannot be woken
Someone who is bleeding heavily and it will not stop with firm pressure
Someone who has had a seizure that will not stop, or does not wake up afterwards
Someone who has lips or skin that look pale, blue, grey or blotchy
Someone who you believe has taken an overdose or swallowed something poisonous

Is any of this happening?
Be seen today
Give naloxone immediately if available.
Do not wait to see whether symptoms improve.
Urgent medical assessment is also appropriate for persistent drowsiness, confusion, repeated vomiting, chest pain, breathing difficulty, or a new injury after opioid use, even if the person is awake.

Book an appointment
Routine follow-up is important after recovery from any suspected intoxication or overdose.
This is a chance to review medicines, obtain naloxone, discuss safer use, and consider treatment or support without judgement.
Every sign above is quoted from the sofidex article on Opioid intoxication. If you are not sure, err upward — it is always reasonable to be checked.
