Coughing does not normally require anti-inflammatory drugs. Coughing itself is a defensive reflex, and normal people also experience coughing, and normal people do not need anti-inflammatory drugs for coughing. Cough is also a symptom of disease. Many diseases can cause cough symptoms, including infectious diseases such as bronchitis, pneumonia, bronchiectasis, tuberculosis, and lung abscess, as well as non-infectious diseases such as mitral stenosis, cough variant asthma, dilated cardiomyopathy, and allergic cough. The anti-inflammatory drugs mentioned actually refer to antimicrobials, which are chemical drugs that have the ability to inhibit bacterial activity or kill bacteria. Therefore, antimicrobials can be used for cough symptoms caused by bacterial infections, such as bacterial pneumonia and lung abscess, while cough symptoms caused by non-infectious diseases or those caused by viral infections do not require the use of antimicrobials.
