Symptomatic and etiologic drugs can be taken appropriately. You can take drugs for relieving cough and resolving phlegm, such as choosing clear lung and phlegm cough granules, compound licorice tablets, lung power cough combination, lantern leaf granules, myrtle oil, compound aminoglutethimide oral solution, compound forcodine oral solution, compound fenagan syrup, etc. Nebulized inhalation with budesonide nebulizer, ribavirin, and chymotrypsin is also an option. Anti-viral treatment can be chosen from antiviral oral solution, fishoil syrup, blue scutellaria oral solution, ribavirin, oseltamivir and other drugs.
