Cefadroxil capsules belong to the cephalosporin group of drugs, do not drink alcohol before and 3 days (one week is recommended) after applying the drug. The main component of alcohol is ethanol, which can be converted into acetaldehyde and acetic acid in the body. If you drink alcohol-containing drinks while taking cephalosporin antibacterial drugs orally, it will cause disulfiram-like reaction, which can be manifested as tachycardia and panic in mild cases, and may cause anaphylactic shock in serious cases, or even life-threatening. Since there is a metabolic cycle for both drugs and alcohol, it is not allowed to drink alcoholic beverages, such as liquor, beer, wine, yellow wine, etc., for 3 days before and after taking cephalosporins, and it is recommended to have a one-week interval between the first and the second days. If there is any discomfort during the medication, you should consult a doctor promptly.
