Pneumonia
"Levaquin and its generic are Fluoroqunilone antibiotics. The FDA has issued a Black Box Warning -- the most severe warning it can issue -- on all Fluoroquinolone antibiotics because they cause so many horrible, longterm side effects (like permanent tendonitis, vision problems, and more). Fluoroqunilones break down the mitochondria of cells, leading to cell death. This damage cannot be reversed."
