Bronchitis for 2 weeks.on 3rd day of z pak (azithromycin). still have fevers, cough, huff and puffing, a horrible soar throat started and runny nose.what should i do?

Finish antibiotics: Go see your doc, especially if by "huff and puffing" you mean "short of breath" or difficulty breathing, in which case, you should go back sooner than later. You've listed z pak, Aldactone (spironolactone) & flexeril, none of which help w/breathing per se. Azithromycin has a long half-life so you only need to finish the pack but it will stay in your system for a 10-14d. New study says average cough can last 18d.
