I have COPD and bullous emphysema. I have had pneumonia for several months. I have done levaquin, then 20 days of cefepime IV 3 times a day. I cleared up substantially. I am now taking an antibiotic called bactrim. I seems to be still hanging around, ie coughing up the yellow/light green sputum and tired. No temperature. Is the pneumonia ever going to go away?
