According to the characteristics of cephalosporins, 24 hours after taking cephalosporins, most of the drugs in the body can be metabolized and the concentration of the drugs in the body is low, so even if you drink alcohol, you may not have serious reactions. However, some cephalosporins may take a longer time to metabolize in the body and some residues may still remain after 24 hours. Drinking alcohol may cause disulfiram-like reactions, so it is recommended to avoid drinking alcohol during and within 1 week after taking cephalosporins. The reason why drinking alcohol after taking cephalosporin is prohibited is that disulfiram-like reactions can occur between the two, usually occurring 15-30 minutes after taking cephalosporin and drinking alcohol, mainly manifesting as facial fever, flushing, dizziness, panic, dyspnea, nausea, vomiting and other symptoms, which may be life-threatening in severe cases. The extent of the patient’s reaction is related to the amount of alcohol consumed and the amount of medication taken, and the attack usually occurs more rapidly. Once it occurs, the patient should seek medical attention promptly to avoid further serious damage to the organism. If the patient has been drinking alcohol 24 hours after taking cephalosporin, there is no need to worry too much, and one can closely observe one’s own reaction and whether there is discomfort. If there is no obvious discomfort, it indicates that the harmful substances can be discharged from the body through natural metabolism. However, if the corresponding symptoms appear, you should seek medical attention in time and do not delay the treatment.
