Once a reaction develops, no more alcohol should be consumed. Such tests should be carried out only when the patient is hospitalized, or comparable supervision and facilities, including oxygen, are available. In severe reactions, whether caused by an excessive test dose or by the patient s unsupervised ingestion of alcohol , supportive measures to restore blood pressure and treat shock should be instituted. Antihistamines have also been used intravenously. Potassium levels should be monitored, particularly in patients on digitalis, since hypokatemia has been reported.
