If a child’s cough is stubborn, it is necessary to diagnose what disease is causing the cough and then treat the symptoms after a clear diagnosis. Coughs are common in children with upper respiratory tract infections, for example, and these children will have coughs, phlegm, sneezing and runny noses, which usually do not require special treatment. Some children with recurrent coughs may be related to multiple repeated infections. If oral medication does not work well, you can try nebulizer treatment, usually choosing drugs such as budesonide and terbutaline. The speed of nebulizer inhalation is better than direct oral medication, and a course of treatment is usually given in about 5 days. Finally, if your child has a stubborn cough, you need to be alert to specific diseases that can also cause a cough to persist, such as tuberculosis and allergies. This type of cough is usually without phlegm, and some children who have been naughty and have inhaled foreign bodies in their airways may also have a recurrent cough, although this is very rare.
