When you cough every day and have a distinct wheeze and bronchial secretions, what medications should you take?

Persistant asthma: Guidelines say start w/ low dose inhaled steroid and as needed rescue inhaler (albuterol). Combo inhaler (advair symbicort (budesonide and formoterol) dulera) might be overkill, but could start w them and ease back when better. Singular less attractive unless allergy a problem too. Should get PFT to assess lung function, and follow up to check progress. Allergy testing for root causes.
