Coughing at night without coughing during the day indicates that it is due to a respiratory infection. The most common diseases are pharyngitis, tonsillitis, bronchitis, and pneumonia, which can be treated with standard antibiotics. If the respiratory infection is caused by a bacterial infection, it can be treated with cefixime tablets. If the cough is due to mycoplasma infection, it can be treated with azithromycin tablets. While taking antibiotic treatment, you also need to pair it with cough and phlegm relieving drugs, commonly used drugs include Yinhuang Qinglung capsule and licorice tablets, etc. If the cough has no phlegm, you can take diphenoxylate tablets. Cough is one of the common clinical symptoms of the respiratory tract and can be cured by using medication.
