The 70-year-old man with frequent sneezing from a cold needs to be treated with detachment from the environment, antihistamines, and glucocorticoids, depending on the cause of the cold, allergies, and rhinitis, respectively. 1. Colds, although colds are caused by viral infections, antiviral treatment is usually not taken. Colds are self-limiting illnesses and can usually be cured on their own by drinking plenty of fluids and getting enough rest. Sneezing symptoms can also disappear after the cold subsides. 2. Allergy, we can’t rule out the possibility of frequent sneezing due to contact with allergens during the course of a cold. It is necessary to use antihistamine treatment such as loratadine in time to avoid further aggravation of symptoms. 3. Rhinitis is also a common cause of frequent sneezing, which is easily overlooked when it occurs together with colds. Glucocorticosteroids, such as budesonide, are usually used to improve symptoms. It is recommended to consult a doctor for examination to clarify the cause of the disease and follow the doctor’s instructions for treatment at the same time.
