Ethanol Toxicity StatPearls NCBI Bookshelf
This article will review the pathophysiology of these intoxications, the clinical presentations, the laboratory workup, and the treatment of toxic alcohol ingestions. This paper will also discuss the limitations of the emergency department workup and how the absence of particular laboratory findings does not necessarily rule out the diagnosis. The toxicity of methanol and ethylene glycol arises primarily from highly toxic intermediate metabolites generated by the action of alcohol dehydrogenase (ADH), the key enzyme in their breakdown. The inhibition of ADH, therefore, becomes a crucial step in treatment (5).

At this stage of intoxication, the person’s behavior will be normal with no visible signs of intoxication, such as slurred speech or delayed reaction time. The condition is usually linked to drinking too many alcohol beverages. But in some cases, people with this condition might have accidentally or intentionally drank household products containing alcohol, such as mouthwash or vanilla extract. Alcohol poisoning can appear similar to many life-threatening conditions. For example, hypoglycemia (low blood sugar), a stroke, or a seizure can cause problems with speech and level of consciousness that may be confused with alcohol consumption.
Alcohol Poisoning Symptoms and What to Do
The half-life of methanol to formic acid is approximately 6 – 18 hours with acidosis developing as late as 20 hours post ingestion (7). Alcohol abuse produces marked alterations in the gastrointestinal tract. Esophageal and gastric dysmotility facilitate acid regurgitation and contribute to postemetic lacerations stages of alcohol poisoning of the distal esophagus induced by vomiting (Mallory-Weiss Syndrome). Liver fibrosis and the resulting intrahepatic pressure increase leads to development of esophageal varicosities. Alcohol promotes chronic gastritis followed by decreased mucosal thickness and atrophy during the chronic phase.
Overcoming drug and alcohol addiction is one of the most difficult challenges you will ever face, but you don’t have to face it alone. If the person is experiencing seizures, a short-term anticonvulsant medication will be given to stop the seizures. Remember, your friend does not have to have all the symptoms to be at risk. Ethanol interferes with the balance of neurotransmitters in the brain by increasing the amount of gamma-aminobutyric acid.
What happens if alcohol poisoning goes untreated?
Given these data, physicians should be careful about confirming or excluding the diagnosis of EG toxicity based on this test, and it should never be used independently when making a decision about initiating treatment (2). ADH has an affinity for fomepizole up to 8000 times greater than that for ethanol. Fomepizole is effective at low concentrations, has a minimal side effect profile, and does not require frequent levels to be checked or close monitoring in the ICU (11). Initially, the cost of fomepizole was a limiting factor to its widespread adoption.
- This latter pathway is particularly relevant following chronic alcohol abuse.
- May include cognitive-behavioral therapy (CBT), individual therapy, group therapy, family therapy, motivational enhancement therapy, or other approaches.
- Normally, anyone experiencing a medical emergency must give permission to receive professional help.
And sometimes, electroencephalography (EEG) is needed to differentiate between alcohol poisoning and a seizure. It can be hard to decide if you think someone is drunk enough to need medical help. You may worry about what will happen to you or a friend or family member, especially if underage.

As Blood Alcohol Concentration Increases—So Do the Risks
Gastric acid secretion and motility vary according to the alcohol content and to the fed state of the individual at the time of ingestion. Beer and wine (low alcohol %) stimulate gastric acid secretion and gastrin release and increase gastric emptying (118). These effects may have little to no consequence following isolated episodes of alcohol ingestion. Moreover, chronic alcohol abuse impairs intestinal essential amino acid and vitamin absorption, leading to increased frequency of nutritional deficiencies, including vitamins A, B1, B2, B6, C, and folic acid (70) (FIGURE 4). Alcohol intoxication, dependence, and withdrawal profoundly affect endocrine regulation and disrupt the body’s ability to maintain and restore homeostasis following a challenge (28).
This is a mechanical way of filtering waste and toxins from the blood. The authors conducted a literature search of primary and secondary sources related to the topic. For treatment recommendations, search restrictions included articles published between 2008 and 2019. For background information, search restrictions included articles written from 1990 – present. If you’ve drunk a dangerous amount of alcohol, doctors may “pump” your stomach.
