Metronidazole contains some other antibiotics, such as cephalosporins, which affect the metabolism of alcohol and produce a disulfiram-like reaction. The clinical manifestations of disulfiram-like reaction are dizziness, headache, nausea, vomiting, drop in blood pressure, and even shock, which is very dangerous to patients, and some patients even lose their lives. For relatively mild symptoms of disulfiram-like reactions can be treated without treatment and can recover on their own, but if the reaction is more intense, such as respiratory depression, deficiency, cardiac dysfunction, it is necessary to send to the hospital for emergency treatment.
