Acute bronchitis is an acute inflammation of the bronchial mucosa caused by various pathogenic factors, with coughing being one of the common symptoms of acute bronchitis. So, how can patients stop coughing when they have acute bronchitis? If the cough is dry or there is little phlegm, antitussive and cough suppressant medications can be used. If the cough produces phlegm that is hard to expel, medications that thin the mucus should be chosen. Treatment can be administered orally or through nebulization. Additionally, drinking more water and having a lighter diet can also help suppress the cough.
