You should never drink alcohol after drinking cephalosporin, because cephalosporin exists in cephalosporin, and cephalosporin can rapidly react chemically with ethanol in alcohol, which is called disulfiram-like reaction. In mild cases, disulfiram-like reactions may occur similar to allergic reactions, such as local rash, rash, itching, redness, swelling, heat, pain, and dysfunction; in severe cases, chest tightness, shortness of breath, palpitations, precordial discomfort and dyspnea; in the most serious cases, neurological confusion, loss of consciousness, delirium, coma, etc. However, the most serious cases are not only that, but even a transient anaphylactic shock may occur and cause death. Therefore, you should never drink alcohol after drinking cephalosporin. If you drink alcohol after taking cephalosporin, you should drink alcohol only after the cephalosporin has been completely metabolized for at least one week, and if you feel unwell during drinking, you must go to the hospital immediately to avoid affecting and delaying your condition.
