ALCOHOL POISONING: DON'T MISTAKE THE WARNING SIGNS FOR JUST BEING DRUNK

ALCOHOL POISONING: DON'T MISTAKE THE WARNING SIGNS FOR JUST BEING DRUNK

15/07/2026

Alcohol poisoning is a life-threatening medical emergency that occurs when a large amount of ethanol is consumed within a short period, resulting in toxic blood alcohol concentrations. Excessive alcohol intake suppresses the central nervous system and can impair vital functions, including consciousness, respiration, cardiovascular function, and body temperature regulation.

Although an individual may stop drinking, alcohol continues to be absorbed from the stomach and intestines into the bloodstream, allowing blood alcohol levels to rise further. Without prompt medical intervention, alcohol poisoning may lead to respiratory failure, aspiration, coma, permanent brain injury, or death.

Causes

Alcohol poisoning most commonly results from binge drinking, where alcohol is consumed faster than the liver can metabolize it.

In addition to alcoholic beverages, poisoning may also occur following ingestion of products containing ethanol, including:

  • Mouthwash 

  • Certain liquid medications 

  • Cooking extracts 

  • Household products containing alcohol 

More toxic alcohols, such as methanol, isopropyl alcohol (isopropanol), and ethylene glycol, may also cause severe poisoning and require emergency medical treatment.

Signs and Symptoms

Clinical manifestations vary according to the blood alcohol concentration and the degree of central nervous system depression.

Common signs and symptoms include:

  • Confusion or altered mental status 

  • Persistent vomiting 

  • Seizures 

  • Slow breathing (fewer than eight breaths per minute) 

  • Irregular or interrupted breathing 

  • Pale, bluish, or cold skin 

  • Hypothermia 

  • Inability to awaken or loss of consciousness 

Importantly, not every patient presents with all symptoms. Any individual who becomes unconscious or is difficult to awaken after alcohol consumption should be considered a medical emergency.

Diagnosis

The diagnosis of alcohol poisoning is based on clinical assessment supported by laboratory investigations.

Healthcare professionals typically perform:

  • Evaluation of airway, breathing, circulation, and level of consciousness 

  • Blood alcohol concentration measurement 

  • Blood glucose testing to identify hypoglycaemia 

  • Blood and urine tests to assess metabolic abnormalities or detect other toxic substances 

  • Additional investigations if ingestion of methanol or other toxic alcohols is suspected 

Prompt diagnosis is essential to determine the severity of intoxication and guide appropriate treatment.

Treatment

There is no specific antidote for ethanol poisoning. Management focuses on supportive care while the body gradually metabolizes and eliminates alcohol.

Treatment may include:

  • Continuous monitoring of airway, breathing, and circulation 

  • Supplemental oxygen when indicated 

  • Intravenous fluids to maintain hydration 

  • Administration of glucose and vitamins when clinically appropriate 

  • Airway protection and mechanical ventilation for patients with severe respiratory depression or impaired consciousness 

For poisoning caused by methanol or isopropanol, haemodialysis may be required to rapidly remove toxic alcohols from the bloodstream.

When Should Emergency Medical Care Be Sought?

Immediate emergency medical attention is required if an individual who has consumed alcohol develops any of the following:

  • Loss of consciousness 

  • Difficulty being awakened 

  • Slow or irregular breathing 

  • Seizures 

  • Persistent vomiting associated with reduced consciousness 

  • Pale, cold, or bluish skin 

Waiting for the individual to "sleep it off" is dangerous because blood alcohol levels may continue to increase even after drinking has stopped.

What Should Not Be Done?

Several common misconceptions may delay appropriate treatment and increase the risk of serious complications.

Do not:

  • Give coffee to "sobering up" the individual. 

  • Encourage walking or physical activity. 

  • Place the person in a cold shower or bath. 

  • Leave an unconscious person unattended. 

These measures do not reduce blood alcohol concentration and should never replace emergency medical evaluation.
