Patients with a bad cough when smoking can be relieved by some measures, such as nebulizer inhalation, taking expectorant drugs, and antibiotic drugs, as follows: 1. Nebulizer inhalation: Usually smoking causes coughing, which is commonly associated with an inflammatory response in the airways, such as bronchitis, and nebulizer inhalation can be chosen, such as using inhalation budesonide suspension combined with chymotrypsin and ambroxol to promote the discharge of airway secretions and relieve coughing symptoms. 2. 2. Take expectorant medications: Patients can also take appropriate expectorant medications, such as carboxymesterol oral solution and ambroxol hydrochloride syrup, and quit smoking in time to avoid smoking again. 3. Take antibiotic medications: For combined bacterial infections, you should choose sensitive antibiotics, such as penicillins, cephalosporins, macrolides and quinolones, which can control inflammation and make inflammation to reduce the cough.
