I can understand your situation and problem. You are mostly having seasonal bronchitis. Your treatment is partially correct. According to standard guidelines, instead of domain 40000, you should start inhaled bronchodilators and inhaled corticosteroid. Domain is having doxophyllin. It is a oral bronchodilator. Inhaled bronchodilators are the treatment of choice for bronchitis as they are having very less systemic side effects and quick onset of action as compare to oral bronchodilators. So discuss this thing with your doctor and get prescription for inhaled bronchodilators and inhaled corticosteroid. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
