Measures to relieve allergic cough in children are as follows: 1. Allergen detection: Parents are advised to take their children to the hospital for allergen detection and to stay away from allergens after clarifying them, so that allergic cough symptoms will be relieved. 2. Anti-allergic treatment: Take anti-allergic medications such as cetirizine and loratadine as prescribed by the doctor, so that your child’s allergic cough symptoms will slowly disappear. Allergic cough often occurs when the seasons change or when spring is in full bloom. It is usually an irritating dry cough with thin, white, foamy sputum. Therefore, parents are advised to seek immediate medical attention and symptomatic treatment once the above-mentioned symptoms are detected in order to promote the normal growth and development of the child.
