Allergic cough in babies is a long-lasting and frequent cough that is stimulated by external allergens and is often referred to as cough variant asthma. Allergic cough in infants is a relatively troublesome condition that cannot be self-healed by autoimmunity and usually requires medication. For coughs caused by allergic rhinitis, the first thing to do is to look for and avoid allergens and usually take anti-allergy medications, airway stabilizing medications, anti-asthma medications, etc. Care should be taken to ensure that the overall course of treatment is followed. If an infant has a severe cough that narrows the airway and affects smooth breathing, consider using bronchodilators to help relieve the child’s symptoms. In addition, younger babies can be treated with nebulized medication inhalation to help them absorb the medication and keep their airways moist, reducing the chance of recurrent allergic coughing. Parents can hydrate their children with allergic coughs in their daily lives to improve the humidity in the air to relieve cough symptoms. Babies with allergic cough usually need medication, but it should not be used indiscriminately. What parents should do is to provide a good environment for recovery.
