Cough symptoms due to tonsillitis in children can be caused by excessive enlargement of the tonsils, which irritates the mucosal tissue of the pharynx and causes a reflex cough; it can also be caused by downward infection, leading to lower respiratory tract disease. In the first case, there is no particularly quick relief, only the ability to control the infection, reduce the size of the tonsils, alleviate the reflex in the throat, and if necessary, use short-term anti-allergy medication to relieve the symptoms. For the second type of combined lower respiratory tract infection, it should be treated with adequate amounts of sensitive antibiotics, penicillin or cephalosporin as the first choice, with different dosing options depending on the degree of the condition. At the same time, coughing and phlegm-suppressing drugs such as aminoglutethimide should be used, as the coughing symptoms can be significantly relieved if the phlegm is coughing up smoothly.
