The following four drugs can be used for treatment:

(1) Inhalation of glucocorticoids is the main anti-inflammatory treatment, and the duration of inhaled glucocorticoids should last at least 3 months to avoid recurrence. Commonly used in clinic are the mixture of hormone and β2 receptor stimulant, such as symbicol and seretide.

(2) Antiallergic drugs such as levocetirizine, loratadine and mast cell stabilizers such as Nedocromil and cromoglycate can also get good results, but they often need to be used continuously for more than 2 weeks. For patients who have recurrent attacks after drug withdrawal, allergens should be identified in time, effective preventive measures should be taken, and allergen vaccine treatment should be given if necessary.

(3) Montelukast, a leukotriene receptor antagonist, and hormone are called "dual-channel" drugs for asthma treatment.

(4) Tracheal dilators, such as inhaled or oral β2 receptor stimulants or/and oral theophylline drugs, can temporarily relieve cough symptoms, but it is not recommended to use them alone for a long time.

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. It is mainly characterized by persistent or recurrent cough for more than one month, often accompanied by paroxysmal cough at night or early morning, less phlegm, aggravation after exercise, no clinical infection, or ineffective after a long period of antibiotic treatment. Bronchodilator treatment can relieve the cough attack, and there are often personal or family allergies.

Some patients' cough is also related to allergy, 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.

allergic cough's symptoms are mainly long-term intractable cough, which usually lasts for more than 3 weeks. It is often induced by inhaling 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 is often aggravated 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.
