The choice of taking medication or nebulizer inhalation treatment when you have cough symptoms depends on the severity of the condition. In most cases, mild cough symptoms only need to take cough suppressant medications, such as carboxymesterol oral solution, tranylcypromine syrup, lantern leaf granules, fenagan cough syrup, dextromethorphan tablets, etc., which can reduce the symptoms of cough. If the cough is more obvious, or even if the cough has more sputum that cannot be expelled and the sputum is sticky, you can choose nebulizer inhalation treatment, such as adding budesonide nebulizer solution, and you can also use chymotrypsin and ambroxol in combination. In case of bacterial infection, you can also choose to use gentamicin nebulized inhalation. In case of viral infection, nebulized inhalation with interferon is also an option.
