I have (likely) viral bronchitis. no fever but on oral steroids albuterol biaxin (clarithromycin) and still short of breath. what now? increase roids?

Depends : Depends how long u have been on treatment. If u just started then be patient. If end of u'r treatments u need to call u'r doc for follow up as u may require her/him to listen to chest again or order CXR. Even possibly to get a spirometry test on u. Inhaled steroids and long acting beta agonist, (Advair/Symbicort/Dulera), may be needed instead of more oral steroids?
