You should not drink beer while taking medicine because beer contains alcohol, which can damage your body. Drugs are metabolized by the liver, so if you drink alcohol after taking medicine, it will increase the burden on the liver and at the same time affect the effectiveness of the medicine. In particular, you should not drink alcohol after taking anti-inflammatory drugs, because the ingredients in anti-inflammatory drugs will interact with alcohol and have a chemical reaction with each other, producing toxic substances that can cause nausea, vomiting, heart failure and other adverse reactions, and in serious cases, shock, endangering people’s lives. In particular, cephalosporins can have a disulfiram-like reaction with alcohol, directly endangering people’s health. Drinking alcohol after taking medicine will also make the patient’s blood vessels dilate, thus increasing the absorption of drugs and increasing the burden on the patient’s heart and kidneys, which is likely to lead to kidney failure, liver failure, heart failure, etc. The consequences are very serious.
