After taking a cephalosporin and drinking a glass of beer by mistake, symptomatic treatment should be carried out according to the specific conditions of the patient. If the symptoms are mild, they can be improved by resting, drinking more water and inducing vomiting. If the symptoms are more serious and disulfiram-like reaction occurs, you need to go to the hospital in time. Cephalosporin is an antibacterial drug. Drinking alcohol after taking cephalosporin can cause disulfiram-like reaction in patients, which can seriously lead to death. 1. If the patient drinks less beer and the symptoms are relatively mild, it can be improved by proper rest, drinking more water, and physically inducing vomiting, such as pressing the thumb against the throat to induce vomiting. 2. If the patient’s symptoms are more serious, with disulfiram-like reaction and symptoms such as shock and fainting at the same time, he/she needs to go to the emergency department of the hospital in time and receive treatment under the doctor’s guidance. (1) First of all, keep the airway open, administer oxygen, establish intravenous access, and give vasoactive drugs such as dexamethasone as prescribed by the doctor for symptomatic treatment. (2) If it causes respiratory distress, tracheotomy is required. Observe the patient’s consciousness, temperature, pulse, heart rate, blood pressure and other clinical changes.
