It is not possible to drink alcohol immediately after cephalosporin injection through intravenous drip, and it is only possible to drink alcohol after stopping the drug for at least 1 week so that it will not cause a disulfiram reaction. Because alcohol and cephalosporin will cause toxic reaction together, disulfiram reaction mainly manifests as facial flushing, palpitations, shortness of breath, chest tightness, and even unstable vital signs, causing a continuous drop in blood pressure, and even leading to respiratory and circulatory failure, resulting in shock and death. If you have already used cephalosporin, you should not touch alcohol for 1 week before and after drinking alcohol.
