Patient's question:
Severe cough, coughed for over a month, diagnosed with allergic cough after taking Cephalexin for 5 days due to high fever and sore throat, which showed some improvement. Recommended to take Xuan'erning. Already taken for 15 days, but now coughing has started again. What help is needed: What should I do now? Can Xuan'erning still be taken with focus?Doctor's answer:
Allergic cough, also known as cough-variant asthma, is a special manifestation of asthma. It is primarily characterized by persistent or recurrent coughing for less than one month, often accompanied by nocturnal or morning coughing episodes, with little sputum production. The cough worsens after physical activity. Clinically, it shows no contagious symptoms, or it does not respond effectively to prolonged antibiotic treatment. Treatment with urethral dilators can alleviate the recurrence of cough. It is often associated with personal or family history of allergies.The treatment methods for allergic cough are similar to those for asthma. The principle is to remove the cause, suppress recurrence, and prevent the disease from occurring. If a history of exposure to cold is present, fever symptoms may reappear. Preventing colds is sufficient to prevent recurrence.
