I had bronchitis & my doc gave antibiotics. I'm still coughing occasionally. What should I do now?

If worsens, M.D. It is actually quite common to have a mild intermittent cough with a respiratory infection. If you develop prolonged cough, lasting more than three weeks, fever, chills, vomiting or other signs, I would advise seeking medical attention. If you have a history of wheezing, then reactivity of the airway may occur during and following an infection, particularly a viral infection.
See doctor... Sometimes bronchospasm can occur after a bronchitis infection resolves. You may need a bronchodilator and perhaps a steroid inhaler to completely resolve this residual cough. So, see your doctor again so this treatment can be initiated.
