In an emergency
Poison Control (US)1-800-222-1222Fireside Project62-FIRESIDE
Overdose signs
- Extreme drowsiness — can't stay awake or be roused
- Confusion, slurred speech, severe loss of coordination
- Slow, shallow, or irregular breathing
- Unconsciousness / unresponsive; limp, floppy body
- Blue lips or fingertips
- Vomiting while sedated (choking / aspiration risk)
- Cold, clammy skin; weak pulse
First response
- Try to wake them — shout, firm sternal rub
- If unresponsive or breathing is impaired, call emergency services
- Place them in the recovery position — critical, they can choke on vomit
- Monitor breathing continuously; be ready to give rescue breaths / CPR
- Never leave them alone to "sleep it off"
- Do not give other drugs, stimulants, or more depressants
For the medical team
Tell the dispatcher: sedative/depressant suspected, what was taken, how much, and when — especially whether it was mixed with opioids or alcohol, which is the main cause of fatal respiratory depression. Flumazenil (a benzodiazepine antagonist) is hospital-only and often avoided; it can trigger seizures in mixed or dependent users.
Resolution
Most depressant overdoses resolve with airway protection, breathing support, and monitoring. The danger is respiratory depression and choking on vomit — sharply worse when combined with opioids or alcohol. GHB/GBL overdoses often involve sudden deep unconsciousness and may self-resolve, but airway protection is essential.
