Levofloxacin
"Permanently damaged and disabled from 500mg x 2 levaquin. Check the black box warnings.  I was healthy young person.  Started experiencing side effects a few hours after administration.   Adverse reactions got worse. it's been almost 5 YEARS and have bodywide peripheral neuropathy, bodywide tendonosis, dry mouth eyes, nose, tinnitus, crepitus all over.  The drug is poison and destroys human as well as bacterial mtDNA.  Just google "Fluoroquinolone toxicity."  There are safer alternatives for pneumonia.   Don't ruin your life with this garbage that the FDA has failed to remove from the market."
