Breathing normally, but won’t wake up?
Call 911 now ↗Normal-looking breathing does not make unresponsiveness safe. Start the call now and follow the dispatcher.
While help is on the way
- Place them on their side and keep their airway clear. If a head, neck, or back injury is possible, follow the dispatcher’s instructions about moving them.
- Watch their breathing continuously. Stay with them if it is safe.
- Give naloxone if opioids may be involved, following the product instructions. Do not delay the call.
- If breathing becomes abnormal or stops, start CPR and use an AED if available. Follow the dispatcher.
Do not give food, drink, or more drugs. Do not try to make them vomit.
