There are more reasons for a strong cough at 11 or 12 pm. The most common cause is cough variant asthma or early symptoms of an asthma attack, which requires a bronchodilator test or bronchial excitation test at the hospital to make a clear diagnosis. Asthma is more common in nocturnal episodes of coughing, and you need to chew a chewable tablet of montelukast sodium before going to bed, which can effectively prevent coughing attacks caused by asthma. In addition, daily nebulized inhalation medication is needed for treatment. Nebulized inhalation of bronchodilators and glucocorticoids are needed, and the two drugs that can be chosen are budesonide and terbutaline. Another cause of coughing at 11:00 or 12:00 p.m. is likely to be an infection. At night, the bronchial smooth muscle contracts, which can aggravate the cough. Anti-infective drugs can be chosen from Pudilan Anti-inflammatory Oral Solution or Blue Scutellaria Oral Solution.
