Allergic cough and asthma are associated with allergens in the environment, such as pollen, dust mites, viruses, animal fur, and food, which severely affect sleep and work and study, and this disease requires aggressive early treatment. If allergic cough and asthma are diagnosed, antibiotics need to be stopped and exposure to allergens needs to be avoided. Glucocorticoids are the main therapeutic drugs, and anti-inflammatory therapy and beta2 agonists are used to reduce the symptoms of bronchospasm. It is important to take rest, keep the room air fresh and avoid spicy, stimulating and fish foods. In addition, antispasmodic and wheezing drugs can be given as symptomatic treatment, such as theophylline, salbutamol and other drugs, and cough with phlegm can be treated with expectorants. Patients with a history of smoking are advised to quit smoking as soon as possible and avoid serious environments to prevent damage to the lungs from dust, smoke and harmful gas inhalation. Antibiotics can be used to control lung infections, such as penicillin, cephalosporins, macrolides and quinolones, and sputum culture and drug sensitivity tests can be performed if necessary.
