You can’t drink alcohol again after drinking cold medicine. Because most cold medicines are compound preparations, which contain many different kinds of Chinese herbal ingredients, western medicine ingredients, such as antipyretic and analgesic drugs, such as acetaminophen, ibuprofen, etc.. In addition, there are some antiviral drugs, such as amantadine and Chinese herbal medicines such as Banlangen, Fishoil, Forsythia, Scutellaria, etc. Most of these numerous drug ingredients are metabolized by the body’s liver, and wine is also mostly metabolized by the liver to complete. At this time, if you drink cold medicine and then drink alcohol, it will increase the time for cold medicine and alcohol to be metabolized in the liver and increase the burden on the liver. Especially for patients with poor liver function, such as suffering from viral hepatitis, fatty liver, alcoholic liver, etc., it is more likely to cause damage to liver function and even acute liver failure. Therefore, it is not recommended to drink alcohol while taking cold medicine.
