Pneumonia is a common disease of the respiratory system, which is an inflammation of the lungs caused by viral, bacterial, mycoplasma, chlamydia and other pathogenic microorganisms. In the course of treatment of pneumonia, the following should be done when the cough becomes severe: first, assess whether the anti-inflammatory treatment is effective, whether the diagnosis is correct, and change the treatment plan if there is another disease or bacterial drug resistance. Secondly, if only the cough becomes stronger, other symptoms and chest X-ray are improving, you can add cough medicine, such as Su Huang cough capsules, Platycodonopsis tablets, etc., to strengthen the cough treatment. In addition, eat less spicy and stimulating food and drink more water.
