A child’s allergic cough can be cured by nebulization in as short a time as 5-7 days, and may take more than a month in the long term. Mild allergic cough is usually a paroxysmal, irritating dry cough, which in some cases is accompanied by a foreign body sensation or tickling in the throat, and can occur both during the day and at night, mostly in the middle of the night and in the morning. One of the main treatments for allergic cough is nebulization. If the allergic cough is mild, nebulization for 5 to 7 days will usually show significant improvement, but for some children with chronic allergic cough that does not resolve, the nebulization time will be longer, and some need to be nebulized for a month or more. At this point, a combination of oral anti-allergy medications, such as loratadine (caution for children younger than 2 years old), can be considered. Allergic cough is one of the very common chronic coughs in children. Usually medication can only provide relief, but the cycle is longer, so parents should be patient.
