After catching a cold followed by coughing, this is often due to viral or bacterial infections leading to pharyngitis, bronchitis, or pneumonia that cause coughing. Under this circumstance, the initial treatment is anti-infection. If it is considered a bacterial infection, then sensitive antibiotics should be added either orally or intravenously; if a viral infection is considered, then the primary treatment is symptomatic. For instance, taking some expectorant and cough suppressant medications, including Western or proprietary Chinese medicines. Concurrently, nebulizer inhalation can be administered to achieve expectoration, spasm relief, and cough suppression. Additionally, intravenous cough suppressants, enhancing back patting, and drinking more warm water can help dilute sputum and promote its expulsion among other treatments.
