Patients should not apply the above drugs within one week after drinking alcohol, and if they do, they may experience symptoms such as flushing, chest tightness, shortness of breath, nausea, vomiting, and drop in blood pressure. When the above symptoms occur, you should go to the hospital as soon as possible and be given anti-allergy treatment, and at the same time, you can be given fluids for diuresis to promote the rapid elimination of the drug to reduce the symptoms. Before applying antibiotics, patients should also be asked whether they have a history of alcohol consumption, if they have consumed alcohol within a week, including all kinds of alcohol, such as white wine, beer, fruit wine, and also drugs containing alcohol, such as patchouli Zhengqi water.
