Therapeutic nerve or ganglion block: Dehydrated alcohol injection 98%: Intraneural: Dosage variable depending upon the site of injection (eg, trigeminal neuralgia: 0.05 to 0.5 mL as a single injection per interspace vs subarachnoid injection: 0.5 to 1 mL as a single injection per interspace); single doses >1.5 mL are seldom required. Note: Administer when pain is from malignant origin only.
Replenishment of fluid and carbohydrate calories: Dehydrated alcohol infusion: Alcohol 5% and dextrose 5%: 1 to 2 L/day by slow infusion.
Septal ablation for hypertrophic cardiomyopathy with left ventricular outflow tract obstruction: Intracoronary: Dosage variable depending on septal anatomy and rate of contrast wash-out: Single dose: 1 to 3 mL of at least 95% concentration infused slowly into septal arterial branches; maximum dose: 5 mL/procedure. Note: Use the minimum dose necessary to achieve the desired reduction in peak left ventricular outflow tract pressure gradient; smaller amounts may reduce the size of the septal infarct and incidence of complications (eg, complete heart block) (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustments provided in the manufacturer's labeling.
Ethylene glycol or methanol toxicity (off-label use): Note: Hemodialysis is considered an adjunct to ethanol in select patients (Ref); consultation with a clinical toxicologist or poison center is highly recommended to determine the optimal patient-specific care. The following dosing adjustments are for any patient receiving hemodialysis regardless of kidney function.
Hemodialysis (intermittent): Maintenance dose: In general, ethanol dose requirements are increased by ~50% during hemodialysis (Ref). Frequent serum ethanol concentrations (eg, every 1 to 2 hours initially and during and after hemodialysis) are required to determine the patient-specific clearance rate and appropriate maintenance dose (Ref).
There are no dosage adjustments provided in the manufacturer's labeling.
The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.
Frequency not defined.
Cardiovascular: Cardiac failure, heart block, myocardial necrosis (excessive), ventricular fibrillation, ventricular tachycardia
Central nervous system: Hyperesthesia, neuritis, pain, paresthesia
Hypersensitivity to ethyl alcohol or any component of the formulation; seizure disorder and diabetic coma; subarachnoid injection of dehydrated alcohol in patients receiving anticoagulants
Ablysinol: There are no contraindications listed in the manufacturer's labeling.
Concerns related to adverse effects:
• Heart block (septal ablation): Transient heart block is common at the time alcohol is injected into a septal artery; ~10% of complete heart block events become permanent and require a permanent pacemaker following percutaneous transluminal septal myocardial ablation. Risk factors for permanent pacemaker dependency include a baseline PQ interval >160 msec, baseline minimum heart rate <50 bpm, baseline left ventricular outflow gradient >70 mmHg, maximum QRS during the first 48 hours >155 msec, third-degree atrio-ventricular block occurring during the procedure, and no clinical recovery between 12 to 48 hours after the procedure.
• Myocardial infarction: Use is intended to create a controlled MI for therapeutic purposes. However, excessive myocardial necrosis and subsequent heart failure have been reported. Factors increasing the risk of excessive tissue necrosis include higher volume of alcohol used and a higher number of septal branches injected to reduce the left ventricular outflow tract gradient.
• Ventricular arrhythmia (septal ablation): Ventricular tachycardia and ventricular fibrillation requiring electrocardioversion occurred at a frequency of approximately 1%. Perform continuous electrocardiographic monitoring for 48 hours after the procedure.
Disease-related concerns:
• Diabetes: Use with caution in patients with diabetes mellitus; ethyl alcohol may decrease blood sugar.
• Gout: Use with caution in patients with gout.
• Hepatic impairment: Use with caution in patients with hepatic impairment.
• Shock: Use with caution in patients with shock.
Special populations:
• Cranial surgery: Use with caution in patients following cranial surgery.
• Older adult: Use with caution in the elderly; the rate of heart blocks, pacemaker dependency, and dysrhythmia following injection into a septal artery increased with age.
• Infants: Minimize dermal exposure of ethyl alcohol in infants as significant systemic absorption and toxicity can occur.
Other warnings/precautions:
• Administration: Parenteral: Proper positioning of the patient for neurolytic administration is essential to control localization of the injection of dehydrated alcohol (which is hypobaric) into the subarachnoid space; avoid extravasation. Not for SubQ administration. Do not administer simultaneously with blood due to the possibility of pseudoagglutination or hemolysis; may potentiate severe hypoprothrombic bleeding. Avoid extravasation during IV administration.
• Antiseptic: Appropriate use: Improper use may lead to product contamination. Although infrequent, product contamination has been associated with reports of localized and systemic infections. To reduce the risk of infection, ensure antiseptic products are used according to the labeled instructions; avoid diluting products after opening; and apply single-use containers only one time to one patient and discard any unused solution (FDA Drug Safety Communication 2013).
• Monitoring: Clinical evaluation and periodic lab determinations, including serum ethanol levels, are necessary to monitor effectiveness, changes in electrolyte concentrations, and acid-base balance (when used as an antidote). Monitor blood glucose closely, particularly in children as treatment of ingestions is associated with hypoglycemia.

Oral: Ethylene glycol or methanol ingestion: After diluting ethyl alcohol to ≤20% solution, administer hourly by mouth or via nasogastric tube. Out-of-hospital management with orally administered ethanol is not recommended but has been demonstrated to be efficacious (Ref). Due to the pharmacokinetics of alcohol (ethyl), it is critical that oral ethanol be administered precisely at 60-minute intervals.
Parenteral: Not for SUBQ administration.
Intracatheter (venous access site): Central venous catheter lock: Instill diluted ethyl alcohol (≤70%) in a volume equal to the internal lumen volume of the catheter to ensure adequate lumen exposure and limit systemic exposure. Ethanol forms a visual precipitate with heparin or citrate; flush catheter well with normal saline before administration (Ref).
IV: Ethylene glycol or methanol ingestion: After diluting ethyl alcohol to 10% v/v solution, infuse initial dose IV over 60 minutes (Ref); central vein is the preferred route.
Oral: Ethylene glycol or methanol toxicity (off-label use): Using a 20% solution, administer hourly by mouth or via nasogastric tube. Out-of-hospital management with orally administered ethanol is not recommended but has been demonstrated to be efficacious when the situation warrants its use (eg, mass poisoning in a resource-limited setting; anticipated delay of medical care) (Ref). Due to the pharmacokinetics of alcohol (ethyl), it is critical that oral ethanol be administered precisely at 60-minute intervals.
IV: Ethylene glycol or methanol toxicity (off-label use): IV administration via a central vein is the preferred route. Administer as a 10% solution in D5W. Initial dose should be administered over 1 hour.
Treatment of occluded central venous catheter: Instill a 70% solution with a volume equal to the internal volume of the catheter. Assess patency at 30 to 60 minutes (or per institutional protocol).
Intraneural: Separate needles should be used for each of multiple injections or sites to prevent residual alcohol deposition at sites not intended for tissue destruction. Inject slowly after determining proper placement of needle. Since dehydrated alcohol is hypobaric when compared with spinal fluid, proper positioning of the patient is essential to control localization of injections into the subarachnoid space.
Intracoronary: Inject small volumes over 1 to 2 minutes percutaneously into septal arterial branches, guided by assessment of the gradient.
Store at room temperature. Do not refrigerate or freeze. Highly flammable; store away from any heat source and keep cool.
Pharmacy supply of emergency antidotes: Guidelines suggest that at least 180 to 360 g be stocked. Suggested amount is stated to be a sufficient quantity to treat 1 patient weighing 100 kg for an initial 8- to 24-hour period (Dart 2018); actual amount to be stocked should take into account site-specific and population-specific needs.
Injection: Therapeutic neurolysis of nerves or ganglia for the relief of intractable, chronic pain in such conditions as inoperable cancer and trigeminal neuralgia (dehydrated alcohol injection) (FDA approved in adults); epidural or individual motor nerve injections to control certain manifestations of cerebral palsy and spastic paraplegia, celiac plexus block to relieve pain of inoperable upper abdominal cancer, and intra- and subcutaneously for relief of intractable pruritus ani (diluted [40% to 50%] dehydrated alcohol injection: FDA approved in adults); induction of controlled cardiac septal infarction to improve exercise capacity in patients with symptomatic hypertrophic cardiomyopathy who are not candidates for surgical myectomy (Ablysinol only: FDA approved in adults); has also been used as an antidote for the treatment of methanol and ethylene glycol ingestion and as a lock solution for the prevention and treatment of catheter-related infections.
Oral: Has been used as an antidote for the treatment of methanol and ethylene glycol ingestion.
Topical: Skin antiseptic (hand sanitizer gels, foams solutions and rubbing ethyl alcohol: FDA approved pediatric patients [age not specified] and adults).

Since a "safe" amount of ethanol consumption during pregnancy has not been determined, the AAP recommends women who are planning a pregnancy refrain from all ethanol intake (AAP 2000).
Ethanol crosses the placenta, enters the fetal circulation, and has teratogenic effects in humans (AAP 2000; Barceloux 1999).
The following withdrawal symptoms have been noted in the neonate following maternal ethanol consumption during pregnancy: Crying, hyperactivity, irritability, poor suck, tremors, seizures, poor sleeping pattern, hyperphagia, and diaphoresis (Hudak 2012). Fetal alcohol syndrome (FAS) is a term referring to a combination of physical, behavioral, and cognitive abnormalities resulting from ethanol exposure during fetal development. Since a "safe" amount of ethanol consumption during pregnancy has not been determined, the AAP recommends those women who are pregnant refrain from all ethanol intake (AAP 2000).
When used as an antidote during the second or third trimester, FAS is not likely to occur due to the short treatment period; use during the first trimester is controversial (Barceloux 1999). Following administration into a septal artery during percutaneous transluminal septal myocardial ablation, systemic concentrations are not expected to result in significant exposure of ethanol to the fetus, however the procedure should be postponed until after delivery when possible.
Ethylene glycol or methanol ingestion: Blood ethanol levels (at the end of the loading dose, every 1 to 2 hours until stabilized, and then every 2 to 4 hours thereafter); blood glucose, electrolytes (including serum magnesium), arterial pH, blood gases, methanol or ethylene glycol blood levels, heart rate, blood pressure.
Symptoms associated with serum ethanol levels:
Nausea and vomiting: Serum level >100 mg/dL (SI: >21.7 mmol/L)
Coma: Serum level >300 mg/dL (SI: >65.1 mmol/L)
Antidote for methanol/ethylene glycol: Goal range: Blood ethanol level: 100 to 150 mg/dL (SI: 21.7 to 32.6 mmol/L)
Ethylene glycol or methanol toxicity (off-label use): Ethyl alcohol competitively inhibits alcohol dehydrogenase (AD), an enzyme that catalyzes the metabolism of ethylene glycol and methanol to their toxic metabolites. AD has a higher affinity for ethanol; therefore, ethanol is preferentially metabolized in patients who have ingested ethylene glycol and/or methanol. As a result, treatment with ethanol prevents the formation of ethylene glycol and methanol toxic metabolites, thereby preventing the development of toxicity.
Neurolysis: Alcohol will destroy nerves at the site of injection.
Septal ablation: Tissue toxin that produces a myocardial infarction when injected through an intra-arterial catheter into a target septal vessel, which causes the hypertrophied septum to thin.
Absorption: Oral: Rapid (Barceloux 2002).
Distribution: Vd: 0.6 to 0.7 L/kg; may be slightly decreased in women (Barceloux 1999; Barceloux 2002).
Metabolism: Hepatic (90% to 98%) (Barceloux 1999; Barceloux 2002) to acetaldehyde then acetate (Zakhari 2006).
Half-life elimination: Rate: 15 to 20 mg/dL/hour (range: 10 to 34 mg/dL/hour); increased in patients with alcohol use disorder (Barceloux 1999; Barceloux 2002).
Excretion: Kidneys and lungs (~2% to 10% unchanged) (Barceloux 1999; Barceloux 2002).
