When a cough persists for 8 weeks or longer or goes away only to come back, that's a chronic cough.What could be causing your chronic cough?
A common but under-recognized cause of a chronic cough in adults is pertussis, also known as whooping cough. Chronic cough can also occur with fungal infections of the lung, tuberculosis (TB) infection or lung infection with nontuberculous mycobacterial organisms. Chronic obstructive pulmonary disease (COPD).What is the best medicine for chronic cough?
The prescription medication gabapentin (Neurontin), an antiseizure medicine, has been found to be helpful in some individuals with chronic cough. Other traditional cough medicines often contain the narcotic codeine or hydrocodone. Though these medicines can help calm your cough, they also cause drowsiness and may become habit forming.
