If a child has a bad cough at night, the following methods can be used to relieve the symptoms: 1. Take cough and phlegm medicine before the child goes to bed to stop the cough and relieve the cough symptoms. 2. Keep the humidity in the room to prevent the child’s throat from becoming too dry and uncomfortable, which can lead to an irritating dry cough. 3. 4. If the child cannot be relieved by actively taking medication, the symptoms of coughing at night should be considered as cough variant asthma caused by allergic factors, which can be treated by inhaling budesonide aerosol. When a child has a bad cough at night, do not take medication blindly, but first clarify the cause and then provide targeted treatment.
