Runny nose is common in most rhinological diseases, such as acute and chronic rhinitis, sinusitis and allergic rhinitis. If the runny nose is mainly clear and accompanied by itchy nose and sneezing, it is often caused by allergic rhinitis, and you can take anti-allergic drugs such as loratadine and topical glucocorticoid nasal sprays such as co-corticosteroid. If the runny nose is the main symptom, accompanied by nasal congestion and headache, it is usually caused by chronic rhinitis and sinusitis, which can be treated with antibiotics, such as cephalosporins. In addition, you can also choose Chinese herbal medicine for treatment, such as Huo Zhi Wan, nasal abnormalities and other drugs.
