Levofloxacin
"I now rarely get sick but I've had sinusitis for years due to my allergies. I've found out from my experience with sinus infections that there is no better drug than LEVAQUIN  for killing a sinus infection. I just went to the doctor for my ears being clogged for about 4 weeks now and she said I have fluid behind my ear drums and prescribed me 7 days of Levaquin 500mg. I'm about to start taking it tonight and in a few days I'll see results... I've used it a number of times for bad sinus infections and it never fails to work w/ no side effects that I can see. Great drug.  :  )"
