A low level of alcohol intoxication causes mild symptoms, while severe intoxication, or alcohol poisoning, can be life threatening. Fomepizole costs more than ethanol in most countries, but an accurate cost comparison needs to include intensive care expenses, need for nursing care and requirement for blood ethanol monitoring 107. The cost of fomepizole therapy may be greater with methanol‐poisoned patients than with ethylene glycol‐poisoned patients due to the lengthy elimination of methanol during ADH inhibition. In the US and in Norway (personal communication), the costs of ethanol for IV use and of generic fomepizole are similar 32. Fomepizole is now on the World Health Organisation List of Essential Medicines 109, which is likely to increase the worldwide availability, hopefully to be followed by a lower price. Few reports are available on the use of ethanol as a treatment for diethylene glycol.
- Zakharov et al. reported that 48% of patients treated with ethanol developed severe intoxication, but did not become comatose, most likely because of the close monitoring of patients given ethanol 16.
- Even if the person survives, an alcohol overdose like this can lead to long-lasting brain damage.
- Patients with ethanol intoxication can usually be observed until they are no longer clinically intoxicated and then discharged.
- These epidemics occur world‐wide, often with high mortality rates 14, 15, 16, 17, 18, 19, 20.
- But consuming large amounts of alcohol, even one time, can lead to serious health complications.
- When a person drinks alcohol, ethanol passes through the digestive system and enters the bloodstream through the linings of the stomach and intestines.
If folinic acid is not immediately available, folic acid can be substituted at the same dose. Has times greater affinity for enzyme alcohol dehydrogenase than methanol does, blocking production of toxic metabolites. Fomepizole appears to reduce the need for haemodialysis, at least in ethylene glycol exposures. This is because of the well‐defined kinetics and simple dosing of fomepizole, allowing haemodialysis to be postponed or omitted in specific cases, particularly if there is limited availability of dialysis 75, 82, 83, 86, 88, 105, 106.
Alcohol and Melatonin: What You Need to Know About Combining These Substances
Drinking such large quantities of alcohol can overwhelm the body’s ability to break down and clear alcohol from the bloodstream. This leads to rapid increases in BAC and significantly impairs brain and other bodily functions. Member of vitamin B-complex that may enhance elimination of toxic metabolite formic acid produced when methanol is metabolized. Leucovorin (folinic acid) is active form of folate and may be substituted for folic acid. These agents prevent formation of toxic metabolites in methanol ingestions (not useful with isopropanol or ethanol ingestions).
None of the three compounds is very acutely toxic by itself 32, 33 and they must be metabolized to toxic intermediates, which takes place through oxidations by ADH and aldehyde dehydrogenase (Figure 1). The initial acidic metabolites lead to metabolic acidosis, whereas the end metabolites mediate organ damage. Methanol is metabolized to formic acid, which produces acidosis as well as retinal and optic nerve damage 34 leading to blindness observed in methanol poisoning. Ethylene glycol is metabolized to glycolic acid, the major acidic metabolite 35 and then to oxalic acid. The latter combines with calcium to form insoluble calcium oxalate monohydrate (COM) which is deposited in the renal tubules 5 and causes the kidney damage 3. Diethylene glycol is metabolized to 2‐hydroxyethoxyacetic acid (HEAA), which produces the acidosis 36 and then to diglycolic acid, which accumulates in the kidney and is the nephrotoxic metabolite 33, 36.
Importance of an Alcohol Overdose Antidote Drug for Emergencies
In one series of five patients who ingested diethylene glycol, treatment with ethanol and haemodialysis was used, albeit with partial success since there was one fatality and two with renal sequelae after 26 months 54. Even so, one animal study indicates that ethanol treatment can block the acidosis and renal histopathology produced by a large dose of diethylene glycol (16.8 g kg−1) 55. In addition to checking for visible signs and symptoms of alcohol poisoning, your doctor will likely order blood and urine tests to check blood alcohol levels and identify other signs of alcohol toxicity, such as low blood sugar. Even when alcohol poisoning doesn’t rise to that level of harm, it can cause serious and lasting damage to a person’s vital organs if it is not urgently addressed.
- Alcohol intoxication refers to a temporary condition that occurs when a person drinks an excess of alcohol at one time.
- Many people consume alcohol because it has a relaxing effect, and drinking can be a healthy social experience.
- This amino acid, often called GABA, reduces central nervous system activity.
- Although clinical evidence is lacking for a therapeutic effect of ethanol alone, several studies have demonstrated that ethanol treatment alters the kinetics of toxic alcohols 56, 57.
Dosing during continuous dialysis can be less frequent due to the apparently lower extraction of fomepizole of 0.08 reported in an unpublished case, compared to 0.71–0.78 with intermittent haemodialysis 79. Cardiovascular, respiratory, and neurological examinations were all unremarkable. Venous blood gas analysis revealed a pH of 7.363, partial pressure oxygen (PO₂) of 28.6 mmHg, partial pressure of carbon dioxide (PCO₂) of 49.1 mmHg, and base excess of -1.2 mmol/L. His serum osmolality was 286 mOsmol/L with an osmolar gap of 22.8 mOsm/kg and an anion gap of 11.4 mEq/L. No abnormalities like pleural effusion or consolidation appeared on the chest X-ray.
An approach to the patient with substance use and abuse
Unfortunately, it appears that the therapeutic benefits of hemodialysis are limited in cases where the toxic alcohols and metabolites have been metabolized and clinical sequelae are established [8]. Furthermore, consensus on thresholds for when to initiate alcohol dehydrogenase inhibitor and dialysis alcohol overdose has yet been established [1, 2, 4]. Similar treatment guidelines and established standard of care have not been formulated for other types of toxic alcohols. Despite the presence of treatment guidelines for methanol and ethylene glycol poisoning, variations exist in their intervention strategies.
Ethylene glycol and methanol concentration thresholds at which fomepizole can be safely discontinued remain to be defined [4]. The vast majority of existing literature on toxic alcohol poisoning is in the form of observational studies and systematic reviews on its epidemiology, clinical presentations, and management. Although predictors for negative long-term consequences of toxic alcohol poisoning have been described [14], there is an overall paucity of data focusing on patient outcomes. Short-term patient outcomes have been mentioned as part of the reports focusing on clinical presentations and management of toxic alcohol poisoning instead of being the focus of studies. Individual observational studies with small sample sizes have examined the neurological and renal sequelae of methanol and diethylene glycol poisoning with variable lengths of follow-up ranging from 2 to 18 months [15,16,17].
Adverse events reported with the use of fomepizole include mild irritation at the i.v. Infusion site, headache, nausea, dizziness, drowsiness, and a bad or metallic taste in the mouth.

This may include medications, procedures, and other treatments that are designed to reduce the amount of alcohol in your body.
- The latter combines with calcium to form insoluble calcium oxalate monohydrate (COM) which is deposited in the renal tubules 5 and causes the kidney damage 3.
- The vast majority of existing literature on toxic alcohol poisoning is in the form of observational studies and systematic reviews on its epidemiology, clinical presentations, and management.
- Titration to serum levels between 0.10 g/dL (100 mg/dL) and 0.15 g/dL (150 mg/dL) typically used.
Severe alcohol intoxication — or alcohol poisoning — is a dangerous condition that requires immediate medical attention. Teenagers and young adults who drink may be at particular risk for alcohol overdose. Research shows that teens and college-age young adults often engage in binge drinking and high-intensity drinking.
