Consumer Reports Health explains the best research, expert evidence, and advice about bronchitis, so that you can understand your treatment options and decide which are right for you.

Key points for people with bronchitis
  • Almost all cases of bronchitis are caused by infection from a virus.
  • Bronchitis that lasts up to three weeks is called acute bronchitis.
  • Chronic bronchitis is diagnosed when you cough up mucus every day for at least three months, two years in a row.
  • Bronchitis usually clears up on its own after a few weeks, but some medications including painkillers, cough suppressants, and antibiotics may reduce your symptoms.
  • If you have asthma, chronic obstructive pulmonary disease (COPD), or heart disease, bronchitis may make your condition worse.
Every year about 5 in 100 people get bronchitis--mostly in autumn or winter. Bronchitis often starts as you're just getting over another illness, such as flu. The main symptom of bronchitis is a bad cough caused by inflammation in the lining of your lungs' airways. You may cough up yellow or green mucus, wheeze and feel short of breath. If you have bronchitis, you don't need to see your doctor unless you're experiencing fever, chest pains, or you're feeling very out of breath.
