Alcohol + Benzodiazepines
Alcohol + Benzodiazepines: the short answerThe classic deadly duo: both amplify GABA, so a few drinks plus a benzo can cause blackouts, stopped breathing, and choking on vomit. If someone mixing these cannot be woken, call emergency services.
Why it’s dangerous
Alcohol and benzodiazepines both work through GABA-A receptors — the brain's main braking system — and together their effects multiply rather than add. Judgment and memory go first (leading to accidental re-dosing), then coordination, then the breathing and gag reflexes that keep you alive. This combination is a fixture in fatal overdose statistics.
What happens
- Dramatic loss of coordination and slurred speech
- Complete memory blackouts, sometimes with bizarre behavior the person cannot recall
- Severe sedation progressing to unconsciousness
- Slowed breathing and suppressed gag reflex — vomit can be inhaled
Warning signs
- Cannot be woken, or keeps passing out mid-sentence
- Slow, shallow, or irregular breathing
- Vomiting while barely conscious
- Blue-tinged lips or fingertips
What to do
- Call emergency services for anyone unresponsive
- Recovery position — this is what prevents choking on vomit
- Stay with them and keep checking breathing until help arrives
- Naloxone does not reverse either of these drugs — call rather than wait
- If you are prescribed benzos, treat 'no alcohol' as a hard rule; if you drink anyway, skip the benzo that day
