Most cases of acute bronchitis go away in 2 to 3 weeks, but some may last 4 weeks. Home treatment to relieve symptoms is usually all that you need. Taking antibiotics too often or when you don't need them can be harmful.

How long does it take to recover from bronchitis?

Most people get over an acute bout of bronchitis in two to three weeks, although the cough can sometimes hang on for four weeks or more. If you're in otherwise good health, your lungs will return to normal after you've recovered from the initial infection.

What happens if you let bronchitis go untreated?

Bronchitis can lead to pneumonia if you don't seek treatment. Bronchitis is an infection of the airways that lead to your lungs. Pneumonia is an infection inside one or both lungs. If bronchitis is left untreated, the infection can travel from the airways into the lungs.
