Cephalosporin should be given only after 3 to 7 days of drinking alcohol, otherwise it may trigger a disulfiram-like reaction.
It takes at least 3~7 days after drinking alcohol before you can take a cephalosporin. Because the cephalosporin drug will produce some metabolites, these metabolites and alcohol fusion in the body, it will be easier to trigger a disulfiram-like reaction, which will show nausea, vomiting, dizziness, and diarrhea, etc., and the more serious patients may also experience a drop in blood pressure and cardiac failure and even life-threatening situations.
Therefore, it is important to allow alcohol to metabolize completely in the body before administering cephalosporin.
To avoid disulfiram-like reactions, do not consume alcohol for 7 days after taking or injecting cephalosporins. It is also important to avoid the intake of foods that contain alcohol, such as alcoholic chocolates and drunken shrimps and crabs.
