Patients with cough without phlegm can use different treatments according to different causes and the specific conditions of the patient. The main treatments are: 1. If the cough is caused by acute laryngitis, patients can use nebulization to relieve the symptoms, and can also be treated with throat-clearing granules and roxithromycin. 2. In some cases, the cough without sputum is caused by allergic factors, which require bronchodilator drugs such as aminophylline and anti-allergy drugs such as loratadine. If the symptoms of coughing without phlegm are more serious, it is recommended that patients should go to the hospital for relevant examinations in a timely manner and then determine the treatment measures according to the examination results.
