Depends: No set time for chronic bronchitis. If you still have bronchitis, take biaxin 500 mg, one tab. Twice a day, continously for 2 weeks. Take Phenergan (promethazine) dm, one teaspoonful 2 to 4 times a day as needed till the cough is better. Also take Allegra 180 mg, 1 tab. At night for 3 weeks. Complete this treatment and you will get better.
