Hi.Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern. Treatment of COPD depends on the cause. As there is no cure, treatment is aimed at reducing symptoms. The best way to prevent chronic bronchitis is not to smoke or be around secondhand smoke. Avoid exposure to inhaled irritants and air pollution, stay away from others who have a cold or the flu, and wash hands frequently to prevent the spread of infection. Initially medicines are prescribed including oral cough suppressants or expectorants,etc. In advance cases bronchodilator inhalers, nebulizer treatments, corticosteroids (inhaled and oral), and in some cases antibiotics are prescribed. Severe cases of COPD may require hospitalization. Quitting smoking is the biggest factor in determining an individual s ultimate prognosis. Untreated or poorly managed COPD can result in permanent and severe damage to the lungs. Hope this information helps Get well soon
