Sneezing, runny nose, and watery eyes are often allergic conditions, and at this time, with a history of exposure to allergens, you need to quickly get rid of the allergens, and then quickly use anti-allergy drugs to relieve symptoms, such as adults can use loratadine, paracetamol, or cetirizine hydrochloride. In children, dexloratadine can be used to relieve symptoms, and the effect is relatively good. In addition, you need to find the allergen of sneezing, runny nose and watery eyes, and then desensitization treatment can prevent the appearance of such symptoms in the future. It is also possible that the sneezing, runny nose and watery eyes are caused by a cold, and this time the use of cold medicine can effectively relieve the symptoms, for example, adults can use Sensac, Quick, 999 cold granules or cold and fever granules. For children, you can use pediatric cold and fever granules, pediatric black beetle fever granules or pediatric aminophenol flavonamide granules, all of which are more effective.
