Question: how long does it take for prednisone to work on bronchitis?
Answer: * Prednisone. Ok, most doctors would say these should ONLY be taken as prescribed by your doctor. These steroids are pure anti-inflammatories, used for just about any inflammatory condition known to man. Usually a "burst" dose of 20-40 mg/d for 5-7 days will do wonders for your cough.
