The medical abbreviation "ETOH" stands for "ethyl alcohol", which is also commonly referred to as "ethanol". ETOH is the main type of alcohol found in alcoholic beverages and can be used as an antiseptic or disinfectant in some medical settings.
In healthcare, "ETOH" may be used in medical records or orders to indicate a patient's alcohol consumption or to specify that an individual should not be given alcohol-based medications or treatments due to a history of alcoholism or other related concerns.
