Cannot be woken
Is breathing slowly, irregularly, or not at all
Has blue, gray, or unusually pale lips or skin
Makes choking, snoring, or gurgling sounds while unresponsive
Collapses, has a seizure, or becomes severely confused
Elsewhere, use your local poison centre or emergency service.

And for anyone, someone who:
is unconscious, or cannot be woken
you believe has taken an overdose or swallowed something poisonous

Is any of this happening?
Be seen today
Give naloxone immediately if available.
Call even if the person wakes up, says they feel better, or refuses help, because breathing problems can return.
If someone has taken more than intended but has no symptoms, contact a poison information service immediately rather than waiting for symptoms.
In the United States, Poison Control is available at 1-800-222-1222.
New sleepiness, breathing changes, repeated vomiting, worsening abdominal pain, or yellowing of the skin after discharge needs urgent reassessment.
