You can’t drink alcohol immediately after drinking Sanjiu Cold & Flu. Cold & Flu contains western drug ingredients such as acetaminophen and chlorpheniramine maleate, in addition to some proprietary Chinese medicine ingredients. If you drink alcohol at the same time when using these drug ingredients, it will increase the risk of adverse drug reactions, most commonly nausea, vomiting, loss of appetite, abdominal pain, diarrhea and other symptoms may occur. In addition, alcohol and drugs need to be metabolized by the liver at the same time, which may also increase the metabolic burden of the liver, resulting in liver function damage, aminotransferase elevation, so you should not drink alcohol immediately after drinking cold and flu. If you drink alcohol 1-2 days after the medication, it may be relatively safe, but drinking alcohol during the cold is not conducive to the healing of the cold.
