Allergic cough, a child, should first get rid of allergic environment and contact allergens. Common allergens are pollen, grass powder, dust mites, eggs, fish and shrimp, irritating gases, etc. The drugs can be loratadine and kairuitan. You can drink ambroxol hydrochloride if you have phlegm. Fluticasone bupropionate inhalation can also be used as aerosol inhalation therapy. If you have dyspnea, you can eat aminophylline and salbutamol. Those with bacterial infection can be treated with antibiotics.

Allergic cough is a kind of cough related to contact with allergens. The common cause is cough variant asthma, which is a special manifestation of asthma. The cough lasts or recurs for more than one month, often accompanied by paroxysmal cough at night or in the early morning, with scanty phlegm, aggravated after exercise, no clinical infection, or ineffective after antibiotic treatment for a long time. Bronchodilator treatment can relieve the cough attack, and there are often personal or family allergies. Some patients' cough is also related to allergies, but it does not meet the diagnosis of cough variant asthma. The cause may be upper airway cough syndrome, allergic cough or non-asthmatic eosinophilic bronchitis caused by allergic rhinitis.

cause of a disease

Contact with allergens in the environment, such as pollen, indoor dust, dust mites, molds, viruses, animal fur, cockroaches, feathers and food, often induces allergic cough. Indoor air pollution and harmful gases, such as chemical gases, including the smell of paint, benzene, formaldehyde and other decorative materials, DDV and other chemical pesticides, incense smoke, lampblack, soot and mosquito-repellent incense smoke are also common causes. Cold air and climate change can also cause cough in these patients. With the improvement of modern living standards, new allergens frequently enter people's lives, and people's opportunities for business trips, travel, vacations, etc. are also increasing, so the contact range of allergens is also increasing. Therefore, it is often difficult to prevent and control allergic cough. Judging from the inconsistency of monozygotic twins in the pathogenesis of allergic cough, environmental factors may play an important role in the pathogenesis of allergic cough.

Allergic cough's symptoms are mainly long-term intractable cough, which lasts for more than 3 weeks. It is often induced by inhalation of irritating odor, indoor air pollution and harmful gases, cold air, contact with allergens, such as pollen, indoor dust, dust mites, molds, viruses, animal fur, cockroaches, feathers, food, etc., exercise or upper respiratory tract infection. Some patients have no inducement. It often intensifies at night or in the early morning. Some patients have seasonal attacks, mostly in spring and autumn. The susceptible population is children and other people with allergic constitution.
