sinusitis
"I have COPD and at least twice a year I suffer severe flare-ups of the condition sometimes requiring hospitalization. Levaquin is the only antibiotic that has been effective. If I take it immediately upon early symptoms of a flare-up, I can avoid hospitalization. I have been taking it several times a year for the last several years and have not experienced any serious side effects. When ever I've been hospitalized for COPD exacerbations, I received higher doses of levaquin and again, with no side effects."
