question: I have had a bad cold all fall, the cat scan showed some emphysema but my Dr was very concerned about infection of the upper lobes and treated me with 10 days of Levofloxacin, 500 mg pr/day the last of these was 8 days ago and I still have a bad cough occasionally with some mucous. How long shouod this take to clear up? I feel much better but still have this cough at time that makes me dizzy trying to dispell the mucous. I had been treated with amoxicillan two weeks before the last ABs.  Thank You,  ROD
