Drinking alcohol while coughing can aggravate the condition, making the cough more severe and difficult to relieve. The effects of drinking on the condition include increased airway sensitivity, aggravation of infection, hemoptysis, and the effect of medication, as follows: 1. Increased airway sensitivity: For example, in patients with cough variant asthma, after drinking alcohol, their airway sensitivity increases further and their cough symptoms worsen, making their treatment less effective. 2. Aggravated infection: In patients with pneumonia, drinking alcohol can lead to increased lung infection, which can aggravate the patient’s condition and prolong the course of treatment. The cough is not conducive to recovery, but also affects the therapeutic effect of drugs, especially when pneumonia patients use cephalosporin antibiotics for anti-inflammatory purposes, which can produce a disulfiram reaction due to drinking, leading to significant discomfort. Therefore, cough patients should be prohibited from drinking alcohol and should be treated in a standardized and rational manner.
