Sneezing is a normal phenomenon in daily life. It can be caused by hot and cold air stimulation, irritating odor, etc., and attention should be paid to avoid stimulation. Persistent sneezing may also be related to diseases, such as allergies and colds, and should be treated with anti-allergy, anti-infection and symptomatic treatment. 1. Allergy: For sneezing caused by allergy, attention should be paid to avoiding contact with allergens such as pollen, dust and animal hair. When the nasal secretion is excessive, saline can be used to rinse the nasal cavity, and antihistamines (such as cetirizine) and glucocorticoids (such as prednisone) can be used reasonably. 2. Colds: For sneezing caused by colds, you should pay attention to exercise and keep warm, and wear a mask when going out in cold weather to reduce the stimulation of the nasal cavity by the cold air; medication can be used such as aminophenol xanthanamine granules, tretinoin nasal spray, and ephedrine nasal drops to improve the ventilation of the nasal cavity; and secondary bacterial infections should be treated with antibiotics such as cefuroxime, roxithromycin, and other anti-infective treatments. Occasional sneezing is generally no need to be overly nervous, if there is persistent sneezing, you can go to a professional hospital for consultation, and follow the doctor’s instructions for medication.
