The phenomenon of total sneezing and runny nose occurs for the following common reasons: First, it is likely that allergic rhinitis has occurred. Allergens stimulate the nasal cavity to produce congestion and edema, and also secrete inflammatory exudates to constantly stimulate the nasal cavity, so the phenomenon of sneezing occurs, and the inflammatory exudates form a nasal discharge. Allergies often occur and need to be quickly removed from the allergen and then treated with anti-allergy medication. For example, adults can use loratadine, paracetamol, cetirizine hydrochloride; in the case of children, they can use desloratadine for treatment, in addition to chewing a chewable tablet of montelukast sodium before going to bed at night, which also has the effect of treating allergic rhinitis.
