Seasonal allergic rhinitis may present with nasal dryness, which requires active treatment of the primary disease. Commonly used treatments include general treatment, medication (e.g. budesonide), surgical treatment, immunotherapy, and so on. 1. General treatment: timely detachment from allergens and avoidance of re-exposure to allergens; increasing the amount of water intake and keeping the humidity of the environment appropriate to alleviate the symptoms of nasal dryness. Use saline to rinse the nasal cavity to reduce the concentration of allergens and relieve the dryness of nasal mucosa. 2. Medication: glucocorticoids such as budesonide can be used to reduce nasal mucosal inflammation; antihistamines can be used to relieve symptoms such as itchy nose, runny nose, sneezing, etc. Commonly used medications include cetirizine, loratadine, etc. Mast cell stabilizers can also be used to alleviate the symptoms of allergy, and commonly used medications include sodium coloured glycinate. 3. Surgical treatment: when the effect of conservative treatment is not obvious, the common surgical treatment is selective neurotomy. 4. Immunotherapy: the patient’s ability to tolerate allergens can be improved through repeated exposure to allergens. Seasonal allergic rhinitis should go to the hospital in time, under the guidance of the doctor to carry out the relevant treatment, strictly comply with the doctor’s prescription medication.
