You should not drink alcohol after taking cephalosporin antibiotics and nitroimidazole antibiotics, such as ornidazole, metronidazole, and tinidazole. Because cephalosporin antibiotics and nitroimidazole antibiotics are the drugs most likely to produce a disulfiram-like reaction with alcohol, alcohol should not be consumed for a week before the application of such drugs, and equally not for a week after the application of these drugs. Therefore, it is important to pay attention to the strict prohibition of drinking alcohol or beverages, drugs, food, etc. containing alcohol, such as alcoholic chocolate and patchouli, before and after the application of these drugs, so drinking alcohol can also react with cephalosporin and nitroimidazole antibiotics. Special care should also be taken to ask patients about such medical history before applying the above mentioned drugs. If there is a history of alcohol consumption, care must be taken not to apply cephalosporin or nitroimidazole antibiotics.
