Allergic rhinitis is prone to complicate bronchial asthma, which results in chest tightness, shortness of breath, dyspnea, and panic. Inhalation of allergens should be avoided and medication and immunotherapy should be given. 1. Bronchial asthma should firstly identify and reduce the exposure to allergens or other non-specific irritants that cause asthma attacks, so that the patient can be detached from and avoid exposure to these risk factors for a long period of time, which can effectively prevent and control asthma. 2. Medication, including relieving drugs and controlling drugs. Relievers are mainly used in acute attacks, including short-acting β-agonists such as salbutamol and terbutaline; short-acting anticholinergics such as ipratropium bromide; and theophyllines such as aminophylline. Controlled medications are used for chronic persistence and to reduce the number of acute attacks. These include inhaled glucocorticosteroids such as fluticasone and budesonide for patients with mild disease and infrequent attacks; intravenous glucocorticosteroids such as prednisone and methylprednisolone for patients with severe disease; and leukotrienes such as montelukast and zalukast. 3. Non-specific immunotherapy, such as injections of BCG and its derivatives, transfer factors, vaccines and so on. The above drugs should be standardized and rationally applied under the guidance of professional physicians and pharmacists. If the symptoms fail to improve or even gradually worsen, you need to go to the regular hospital in time, cooperate with the doctor to improve the examination and standardized treatment.
