Depends: Generally, a chronic cough is defined as one lasting more than 8 weeks. The most common causes include post nasal drainage, reflux, and asthma. Depending on the cause, the treatment is different. For example for asthma, inhaled corticosteroids are the mainstay. It's best to see your doctor for testing to determine cause. Your smoking status is also important.
