Frequent sneezing, runny nose, nasal congestion, sometimes with itchy eyes, conjunctival congestion or tearing, consider allergic rhinitis. In recent years, its incidence has been increasing year by year, which will not only affect patients’ daily life, work and study, but also bring a great economic burden. At present, for the clinical treatment of allergic rhinitis, oral antihistamines can be preferred for patients with mild symptoms or intermittent attacks, which can reduce the patient’s symptoms. For patients with severe symptoms, nasal topical inhalation antihistamines or inhaled glucocorticoids can be used for better anti-inflammation and better improvement of clinical symptoms. Alternatively, oral leukotriene receptor modulators, such as montelukast, can be used in combination for synergistic therapeutic effects.
