urinary tract infection
"I was given 500mg Levofloxacin for a UTI infection.   Severe lower back pain that comes and goes.  Pain in my legs that comes and goes.  Horrible medicine.  Now I know it's an Anthrax Drug which I have refused to take in the past.  My doctor just slipped this one in under a name different than Cipero.  I would not recommend this medicine to anyone unless they have Anthrax.  Try Keflex.  It's a great drug with very few side effects."
