From the perspective of traditional Chinese medicine, the lack of ventilation and phlegm in the nose is a wind-heat type of cold. In this case, you can take medicines to dispel wind and heat, such as Pu Di Lan, Da Ye Qing and Yin Qiao Detoxification Tablets, which can play a role in clearing heat and detoxification. From the Western medicine point of view, the nose is not ventilated and phlegm is high in bacterial colds. At this time, respiratory quinolones such as levofloxacin can be applied, or β-lactam antibiotics such as penicillin, or cephalosporins such as amoxicillin can be applied, and anti-inflammatory drugs such as azithromycin and roxithromycin can also be applied for symptomatic treatment. It is also necessary to monitor the body temperature to see if it is elevated. If the body temperature is excessively elevated, antipyretic and analgesic drugs such as ibuprofen, compound aminobarbital, and para-aminosalicylic acid can be applied for effective relief. Local physiotherapy can also be applied, such as nasal ultrashort wave therapy and microwave physiotherapy can relieve nasal obstruction, increased secretions and other conditions.
