Sinusitis
"On day 5 of 10 of 500mg tablet.  Other antibiotics have become unable to cure my sinus infections which I always allow to get really bad before going to the doctor.  After the first dose I had a headache for 2.5 days, can&#039;t say that is from the Levofloxacin or not.  Not sick at my stomach, just no desire to eat for the last 5 days. On day three the sinus infection in my nose/pressure seemed greatly improved but this has settled into my chest also, and a temperature of 101.07.  I hope it works as well on the lung infection.  This is a wonderful medicine with little side effects for me.  I have been completely wiped out for five days.  Just taking a shower and shaving today felt like I had run a marathon.  Great antibiotic for sinus infections!"
