Thank you very much for the useful information Gloria.
Acute bronchitis is usually a viral infection (in over 90% of cases) and takes 2-4 weeks to settle down completely. Some times the course may be prolonged and this may take up to 6 weeks to resolve.
In such viral infections only supportive treatment is required (like the one you are getting) which include expectorants, cough suppressants, steroids and bronchodilators etc.
Honestly you are almost getting maximum treatment for acute bronchitis, and this should start improving with in few days.
However, as per standard guidelines, you must have a chest x-ray as well as CBC done. I say this because there are always chances of secondary bacterial infections (whenever you have prolonged viral illness and especially if you are taking steroids).
Also we are not sure whether the underlying etiology of this episode of acute bronchitis was viral or bacterial (which happens in less than 10% of the cases).
Therefore, you should have a re-evaluation done, preferably by a pulmonologist, and if deemed necessary you would need a round of antibiotics in addition to the drugs you are already taking.
Keep yourself adequately hydrated.
Honey water will be very useful (due to anti-inflammatory properties).
Steam inhalation (will provide a soothing effect).
Watchfully monitor your symptoms for another 48 hours. If they do not improve or get worse, see your doctor again, discuss the details i have mentioned and get a management plan chalked out that suits best to your needs.
I would have been worried too if I were at your place, but let me reassure you that this does not sound serious at all. It is a treatable condition and carries a good prognosis with appropriate management.
It was a pleasure assisting you and thank you very much for visiting us.
