It is best not to drink alcohol when patients are taking cold medicines, at least stop taking medicines for 3 days, and wait for the medicines to be metabolized in the body before drinking alcohol. At present, most of the cold and flu medicines are divided into Chinese medicine and western medicine. 1. Western medicine: Western medicine has non-steroidal anti-inflammatory drugs, and antibiotics. If you take cephalosporin antibiotics, you may experience disulfiram-like reactions, or even life-threatening conditions such as hypotension and shock. Alcohol consumption is strictly prohibited while taking the medication. NSAIDs include paracetamol, which is acetaminophen, and even if you take a small amount of it, but drink alcohol at the same time, you may experience drug poisoning. 2. Proprietary Chinese medicines: The ingredients of proprietary Chinese medicines mainly include ephedra, cinnamon sticks, Pueraria lobata, perilla leaves, antifungal, dahuric dahurica, etc. The medicines and alcohol pass through the liver. Drugs and alcohol are metabolized by the liver, so drinking alcohol after taking medication will cause stimulation of the human liver, affecting the body detoxification and metabolism, and may affect the efficacy of the drug, and may cause the occurrence of adverse drug reactions. During the cold period, patients should pay attention to drink more water, eat more vegetables and fruits, take three meals with light and easy to digest food, and lower the temperature in time. If there is no improvement in the cold situation, the patient is best to go to the hospital for relevant examinations, according to the cause of treatment.
