Question
The child has symptoms of nasal mucus and cough, without fever. They have taken a compound guaifenesin oral solution, but the cough has not shown significant improvement, with phlegm present. Please provide effective treatment methods and medication selection advice.
Answer
Upper respiratory infections are common in children, with symptoms including tickling cough, itchy throat without phlegm, day and night, not accompanied by asthma or rapid breathing. The child may have a lack of appetite, runny nose, and occasionally a low fever with a body temperature not exceeding 38°C. After the fever subsides, the symptoms disappear, but the cough continues for 3-5 days. It is recommended to keep the indoor humidity moderate, using a humidifier, etc. If the symptoms persist for a week without improvement, seek medical attention as soon as possible.
