Alcohol should never be consumed a week before or after taking cephalosporin antibiotics and during the period of taking cephalosporin antibiotics, otherwise it may be life-threatening. Because cephalosporin antibiotics and alcohol can cause allergic reactions, manifested as chest tightness, shortness of breath, laryngeal edema, cyanosis, dyspnea, increased heart rate, decreased blood pressure, weakness of limbs, facial flushing, excessive sweating, insomnia, headache, nausea, vomiting, blurred vision, drowsiness, hallucinations, trance and even anaphylactic shock with loss of consciousness. In addition, the severity of disulfiram-like reactions is directly proportional to the dose of drugs applied and the amount of alcohol consumed, and the occurrence of allergic reactions can be life-threatening if they are severe or not handled in time. In short, as long as alcoholic beverages, generally will react with cephalosporin antibiotics, so do not drink alcohol after taking cephalosporin in order to be safe.
