Cephalosporin antibiotic infusion can drink alcohol after seven days of discontinuation, during the application of cephalosporin anti-infective, as well as within seven days of discontinuation of the drug should not drink alcohol to avoid disulfiram-like reactions. Cephalosporin antibiotics belong to the beta-lactam antibiotic class, with a half-life of around six to eight hours, and require up to a week in the body to be metabolized. If alcohol is consumed while taking the medication, a disulfiram-like reaction can occur, which can be life-threatening in severe cases. Disulfiram-like reaction is manifested as impaired metabolism of alcohol, which will prevent the normal metabolism of ethanol, even if a small amount of alcohol consumption will cause acetaldehyde poisoning, manifested as facial flushing, visual impairment, conjunctival congestion, headache, dizziness, shortness of breath, dyspnea, irritability, nausea, vomiting, heart rate acceleration, and in severe cases, shock or even death. Note that, in addition to abstaining from alcohol within one week of medication, one should not consume any food containing alcohol, such as alcohol-centered chocolates, patchouli, drunken crabs, beer ducks, etc., and should not orally or intravenously apply medicines containing alcohol, or disinfect the skin with a large amount of alcohol or scrub the skin to cool down the temperature.
