Regular Doctor. "bronchitis" is usually a viral upper respiratory infection, but can be caused by irritants (eg: smoke), allergens, & sometimes bacteria. Your doctor may prescribe cough medication (otc meds don't work well), inhalers for wheezing (can cause dry cough), or anti-inflammatories such as prednisone. Antibiotics are often (over) prescribed, sometimes to placate patients. Your regular doctor is perfect.
