alcohol poisoning, poisoning caused by the ingestion of any of several alcohols, of which ethyl, isopropyl, and methyl are the most common. Ethyl alcohol (ethanol) is found in beverages, hairspray, and mouthwashes; ordinarily, it is lethal only if large quantities are ingested in a brief period. Isopropyl (rubbing) alcohol is more toxic. Methyl alcohol (methanol) is extremely poisonous: In addition to nausea, vomiting, and abdominal pain, it may cause blindness; death may follow the consumption of only 2 oz. Treatment for alcohol poisoning may include gastric lavage and other supportive interventions.
