In general, it is safer to drink alcohol for 72 hours before you can take cephalosporins. It takes some time to metabolize cephalosporin antibiotics in the body, and it also takes some time to metabolize alcohol in the body. Generally speaking, after 48 or 72 hours, the alcohol in the body can be completely metabolized clean, and it is relatively safe to eat cephalosporin, otherwise it will easily lead to disulfiram-like reaction, which is very dangerous. If you drink alcohol and immediately take cephalosporin, you need to go to the hospital immediately for resuscitation treatment, otherwise it will easily lead to death. Gastric lavage treatment can be used to discharge the ethanol in the stomach and reduce the absorption of ethanol, or intravenous dexamethasone or intravenous naloxone for symptomatic treatment, intravenous glucose and vitamins for liver protection treatment, which can promote the metabolism of ethanol.
