Patients should drink alcohol after a week of discontinuing cephalosporin to be safer. Cephalosporin is a broad-spectrum antibiotic, often used clinically for infectious diseases. If patients drink alcohol after using cephalosporin, it will lead to abnormal metabolism of alcohol, and then clinical symptoms, called disulfiram-like reaction, such as rapid heartbeat, red face, shortness of breath, and sometimes laryngeal edema, leading to breathing difficulties, and some people may also experience a drop in blood pressure, or even cardiac arrest, at which point There is a risk of life. Therefore, it is recommended that patients must not drink alcohol when using cephalosporin, and should not drink alcohol immediately after stopping the drug, because the metabolism of antibiotics takes some time, usually 3-5 days before the metabolism can be completed. However, each person’s constitution is different, so for safety reasons, it is recommended that patients consider drinking alcohol 1 week after stopping the medication. In addition to cephalosporin, there are other antibiotics that should not be used with alcohol, so be sure to read the instructions when using them.
