I am taking Biaxin,3rd day out from a 10day script.My mucus was originally greenish yellow before going to doctor.When I went to see him it was then clear.After 3 days on Biaxin should'nt I see some progress? My mucus is still mainly clear,prolonged and plentiful and occassionaly bloody in the morning.What can I expect from this medication.Last year I had bronchitis and doctor prescribed Biaxin after another med. did'nt work.I was out of work for about 3 weeks at that time.I feel ok, but am bothered by all this clear mucus when I believe it should be somewhat clearing up by now.
