If you have acute bronchitis, your symptoms may last from a few days to a few weeks or more.

Slight fever (100° to 101° F or 37.5° to 38° C)
These symptoms usually last 3 to 5 days.
Then you get a cough. The cough:

How is acute bronchitis treated?
Your doctor will treat your symptoms:
If you have fever or chest pain from coughing, you can take over-the-counter medicines such as acetaminophen or ibuprofen
If you have wheezing, your doctor may prescribe an inhaler (a little spray bottle with medicine that you breathe in)
Cough medicines almost never make you feel better, but some can help a little at night if your cough keeps you from sleeping.
Doctors used to think antibiotics would help if your mucus was thick and yellow. Now they know antibiotics don't work in acute bronchitis except in the rare cases when it is caused by bacteria.
