How long does it take for bronchitis to go away?

Depends: This is only answered by the etiology of the bronchitis. Viral bronchitis, the most common, usually resolves within 1-2 weeks, but there can be ongoing residual cough that takes weeks to months to resolve. Bacterial bronchitis responds to antibiotics, with the same post-infectious course. Inflammatory and asthmatic bronchitis can go months, depending on the level of control.

Depends: It all depends on the cause: viral- until your body's defense mechanisms fight it off (antibiotics don't work here.) bacterial- same as above with also with the aid of antibiotics irritant (smoke, fumes, etc.)- after the exposure clears and the bronchial cells heal allergen (pollens, molds, etc.) - after the exposure clears and the histamine cells are no longer "sensitive.".

Acute?: There are 2 types of bronchitis: acute and chronic. Acute bronchitis is typically due to airway infections and lasts about 10-14 days. Chronic bronchitis is a form of COPD and is not curable although treatments are available.
