Allergic cough is generally not contagious. Allergic cough is usually caused by the high responsiveness of the airway after contact with allergens, which causes cough symptoms in patients. For patients with allergic cough, some cough relieving drugs can be used, as well as some drugs to reduce airway hyperresponsiveness, such as ketotifen, montelukast, compound methoxynamine granules, procaterol, suhuang cough stopping capsule, Qiangli loquat dew and other drugs. The most important thing is to avoid contact with allergens. You can check allergens. Common allergens include mites, pollen, or some irritating gases. This kind of patients should be avoided, or seafood may also be possible. It can be comprehensively judged by checking lung function, IGE index, eosinophils in blood routine, etc.
