Patients who have allergic rhinitis and always have sneezing and runny nose indicate that the patient’s symptoms are serious. It is recommended to first apply anti-allergy drugs to reduce clinical symptoms, such as cetirizine hydrochloride oral solution or levocetirizine hydrochloride dispersible tablets, which are recommended to be applied selectively. If the patient’s symptoms improve significantly after active treatment, the oral anti-allergy medication can be discontinued and the nasal spray can be continued to consolidate the treatment until the patient’s clinical symptoms disappear completely, and if necessary, further consultation at the hospital can be considered.
