Do not eat fermented grains while taking cephalosporins or intravenous cephalosporins. Because the fermented grains contain certain alcohol components, the simultaneous use of alcohol and cephalosporins may affect the metabolism of alcohol in the human body, and even lead to acetaldehyde poisoning, resulting in disulfiram reaction, which can be life-threatening. Cephalosporins should not drink alcohol during use, nor should they eat any food or even drugs containing alcohol. For example, Huoxiang Zhengqi water contains a lot of alcohol, so it should not be used with cephalosporins at the same time. In addition to cephalosporins, ketoconazole, furazolidone and metronidazole should also be avoided at the same time as alcohol. Because wine and cephalosporins are together, it can cause disulfiram-like reaction, dizziness, palpitation, nausea, chest tightness and shortness of breath, which may be life-threatening in severe cases. So you can't use cephalosporins for a week after drinking. Cephalosporin hung up this afternoon, and now I feel a little chest tightness, so I can observe it for the time being. If the chest tightness gets worse, I need to go to the hospital immediately. It is recommended to drink plenty of water to promote metabolism, and do not use cephalosporin metronidazole antibiotics for the time being.
