From mid-August to October is the high season of allergic rhinitis. Spring is also the peak of allergic rhinitis attacks, and some patients have perennial attacks. Most patients with allergic rhinitis will have bronchial asthma sooner or later, and some patients have allergic rhinitis after existing bronchial asthma. Therefore, allergic rhinitis and bronchial asthma are interrelated and interact with each other. Allergic rhinitis and allergic asthma are actually allergic reactions occurring at different sites. Therefore, the concept of “one airway, one disease” has been proposed, indicating that allergic rhinitis and bronchial asthma are the same inflammatory disease, and rhinitis and asthma should be synchronized in the prevention and treatment. In the north, late August to October is a good season for allergic rhinitis with asthma, and at its peak these patients account for more than 50% of respiratory specialist clinics. Patients often have existing nasal symptoms and then develop asthma symptoms. Therefore, it is especially important to prevent allergic rhinitis. For patients with significant seasonality, nasal spray hormone can be applied starting 10 to 14 days before the annual rhinitis attack to prevent rhinitis attack or reduce the attack, with the aim of preventing asthma attack. Once a rhinitis attack occurs, the patient should visit the ENT department as early as possible to eliminate or relieve the symptoms as soon as possible through integrated Chinese and Western medicine treatment. Once an allergic rhinitis with asthma attack occurs, it needs to be treated by a specialist. The first step in treatment is to identify the allergen, educate the patient to avoid contact with the allergen or implement desensitization therapy, or use corticosteroids and anti-leukotriene drugs to treat both allergic rhinitis and asthma. Treatment of allergic rhinitis should be done at the same time as asthma, and treatment of allergic rhinitis should be done at the same time as asthma. Aggressive and effective intervention and treatment can prevent allergic rhinitis from triggering or exacerbating asthma.
