pneumonia
"I have COPD and experience many lung infections. Also allergic to penicillin.  I have used many different antibiotics and find best results with Biaxin XL  1000mg once daily.  it does not bother my stomach at all.  I usually experience relief within 2-3 days  Doctor gives me 10 day run of it... I  sometimes take prednisone along with it on a 5 day blast 30mg a day... prednisone is very good for lessening inflammation in the airways.. leaves you sleepless, a little agitated but works."
