It is not recommended to take cephalosporin orally after taking patchouli, because patchouli contains alcohol, and its solution is ethanol, and alcohol can easily produce a disulfiram-like reaction with cephalosporin. If a disulfiram reaction occurs, some patients may have more serious consequences. Patients with mild symptoms may experience dizziness, palpitations, flushing of the face, panic, shortness of breath, and serious patients may have clinical symptoms similar to anaphylaxis, and some patients may be life-threatening and critical. Therefore, it is best not to use cephalosporin when you finish taking patchouli, and it is best to consider applying cephalosporin treatment only after taking the drug for more than 3 days. Some patients may have metabolism-related problems, such as liver and kidney insufficiency, then this time should be extended to at least 5-7 days or more. Normally, the time to take cephalosporin after drinking alcohol is shorter than the time to drink alcohol after taking cephalosporin, because alcohol is metabolized relatively quickly.
