Alcohol Poisoning: Signs, Symptoms, and What to Do

Alcohol Poisoning: Signs, Symptoms, and What to Do — evidence-based information from Trailhead Treatment Center.

Key Takeaways

  • Alcohol poisoning kills approximately 2,200 Americans per year — an average of 6 deaths per day.
  • Alcohol poisoning occurs when blood alcohol concentration (BAC) reaches levels that suppress vital functions including breathing, heart rate, and gag reflex.
  • Critical signs include unconsciousness, slow or irregular breathing (fewer than 8 breaths/minute), blue-tinged skin, low body temperature, seizures, and vomiting while unconscious.
  • BAC can continue to rise even after a person stops drinking because alcohol in the stomach and intestines continues to be absorbed.
  • NEVER put an unconscious drunk person to sleep to "sleep it off" — they could die from aspiration, respiratory depression, or hypothermia.
  • Call 911 immediately if you suspect alcohol poisoning. Most states have Good Samaritan laws that protect callers from legal consequences.

What Is Alcohol Poisoning?

Alcohol poisoning is a serious and sometimes fatal consequence of drinking large amounts of alcohol in a short period. When BAC rises to dangerous levels, the areas of the brain controlling basic life functions — breathing, heart rate, and temperature regulation — begin to shut down.

Signs of Alcohol Poisoning

Know these warning signs — they could save a life:

What to Do

  1. Call 911 immediately — do not wait
  2. Stay with the person — do not leave them alone
  3. Turn them on their side (recovery position) to prevent choking on vomit
  4. Keep them warm with a blanket
  5. Be ready to provide information to paramedics (what they drank, how much, when)

What NOT to Do

BAC and Danger Levels

| BAC Level | Effects | |-----------|--------| | 0.08% | Legal impairment (driving limit) | | 0.15% | Significant impairment, vomiting possible | | 0.25% | Severe impairment, passing out likely | | 0.30% | Loss of consciousness, life-threatening | | 0.35%+ | Comparable to surgical anesthesia, potentially fatal | | 0.40%+ | Fatal for most people |
