Cephalosporin is a broad-spectrum antimicrobial agent that belongs to the beta-lactam class and is a prescription drug. It is important to note that cephalosporin should not be injected after drinking alcohol, because cephalosporin and alcohol are prone to co-occurrence of severe allergic reactions, i.e. disulfiram-like reactions, and can also easily lead to death of the patient. In addition, it should also be selected according to the results of the pathogenesis, and the drugs should not be used blindly, because each drug is prone to side effects, commonly liver and kidney damage, and even serious ones can lead to abnormal coagulation mechanisms in the body and induce bleeding events.
