Allergic cough is more difficult to cure and is mainly relieved by anti-inflammatory and anti-allergy treatments, while desensitization after clarification of the allergens may make a cure possible for some patients. Allergic cough is mainly due to the stimulation of allergens such as dust mites and pollen, which activate the accumulation of inflammatory cells in the airways and induce an inflammatory reaction, thus causing cough. Medications for the treatment of allergic cough include the anti-allergy drug loratadine and anti-airway inflammatory drugs such as budesonide formoterol powder inhaler. This type of medication can control the symptoms for a long period of time, but it does not break the root cause. Desensitization is a specific, cause-specific treatment. The patient’s allergens are targeted using low to high doses of medication to allow the immune system to gradually tolerate them. When a certain dose is reached and maintained for a certain period of time, the patient shows adaptation to this allergen and shows no or less allergic symptoms, thus achieving the effect of eradication. Allergic cough patients are advised to go to regular hospitals for consultation and standardized medication under the guidance of doctors. Daily life needs to stay away from allergens, and take protective measures when going out.
