Patients with colds and coughs are generally not allowed to drink red wine. In addition to coughs, patients with colds often have fever, nasal congestion, runny nose and sore throat, especially in the case of fever, which can cause a significantly faster heartbeat. Red wine is mainly composed of ethanol, or alcohol, and alcohol can also cause a faster heartbeat, especially in an intoxicated state, so if a patient with a cold or cough drinks red wine, it may aggravate the clinical symptoms of the cold. If a patient with a cold or cough also has a combined bacterial infection, they need to take antibiotics, such as cephalosporin antibiotics, which are prone to disulfiram-like reactions with alcohol, so red wine is not recommended when you have a cold or cough.
