Ethanol poisoning is caused by drinking too much alcohol.
This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local emergency number (such as 911). You may also consult with a poison control centre in your region.
Alcoholic beverages, including:
Symptoms may include:
- Abdominal pain.
- Confusion, slurred speech.
- Internal (stomach and intestinal) bleeding.
- Slowed breathing.
- Stupor (decreased level of alertness), even coma.
- Unsteady walking.
- Vomiting, sometimes bloody.
- Chronic alcohol overuse can lead to additional symptoms and multiple organ failure.
If you can wake an adult who has had too much alcohol, move the person to a comfortable place to sleep off the effects. Make sure the person will not fall or get hurt.
Place the person on their side in case they throw up (vomit). DO NOT make the person throw up unless told to do so by a health care professional or Poison Control.
Check the person frequently to make sure their condition does not get worse.
If the person is not alert (unconscious) or only somewhat alert (semi-conscious), emergency assistance may be needed. When in doubt, call for medical help.
Before Calling Emergency
The following information is helpful for emergency assistance:
- Person’s age, weight and condition
- Name of the drinks consumed (ingredients and strengths if known)
- Time it was swallowed
- Amount swallowed
However, DO NOT delay calling for help if this information is not immediately available.
Your local poison control centre will vary by city and province, but can generally be reached by telephone 24 hours a day, seven days a week. You can find select contact numbers for Canadian centres here.
What to Expect at the Emergency Room
The health care provider will measure and monitor the person’s vital signs, including temperature, pulse, breathing rate, and blood pressure. The person may receive:
- Airway support, including oxygen, breathing tube through the mouth (intubation) and ventilator (breathing machine)
- Blood and urine tests
- Chest x-ray
- CT (computerized tomography or advanced imaging) scan, to rule out other problems or complications
- ECG (electrocardiogram, or heart tracing)
- Fluids through the vein (intravenous or IV)
- Medicines to treat symptoms
Survival over 24 hours past the drinking binge usually means the person will recover. A withdrawal syndrome may develop as alcohol levels in the blood drop, so the person should be observed and kept safe for at least another 24 hours.
