Coughing even after taking anti-inflammatory drugs is only treated for the etiology of the bacterial infection, but not for the symptomatic treatment. Even in bacterial lower respiratory tract infections, patients need to be treated with effective antibiotics along with the necessary cough medications, such as compound licorice tablets and compound methocarbamol capsules. Some patients with increased airway sensitivity due to inflammatory infections may also require additional treatment with ketotifen or montelukast to reduce airway sensitivity. Some coughs can also be caused by non-bacterial infections, for example, patients with tuberculosis should be treated with effective anti-TB therapy. For cough variant asthma, upper airway syndrome, gastroesophageal reflux cough, etc., symptomatic treatment must be given to address the cause, when antibiotics alone are ineffective. Therefore, patients with cough should not abuse antibiotic treatment, but should be treated with specific treatment after the cause is clearly identified.
