These drugs target Mitochondria in Humans and alter our DNA.
Below is an excerpt from research published last summer. Source URL included so you may read the entire thing for yourself. This and my last post may be helpful for you to bring to your Dr appointments – be sure to show them these if you’re getting resistance from your Doctor on the serious side effects of this class of drugs.
This study explicitly lists Quinolones – the class that Levaquin, Avelox and Cipro belong to. This is not the only study, just the most recent.

“It has been suggested that bactericidal antibiotics induce the formation of toxic reactive oxygen species (ROS) in bacteria. We show that clinically relevant doses of bactericidal antibiotics—quinolones, aminoglycosides, and β-lactams—cause mitochondrial dysfunction and ROS overproduction in mammalian cells. We demonstrate that these bactericidal antibiotic–induced effects lead to oxidative damage to DNA, proteins, and membrane lipids. “
