US FDA recently issued a warning that fluoroquinolone antibiotics, taken by mouth or injection, carry a risk for permanent peripheral neuropathy; Cipro (ciprofloxacin) and Levaquin (levofloxacin) are examples
This is not the first warning issued for this class of antibiotics; in 2008 the FDA issued a black box warning about severe tendon damage and actual tendon ruptures
Two other recent studies found that fluoroquinolones increase your risk for acute liver toxicity (if you’re over age 66), and destabilize your blood sugar if you’re diabetic
Fluoroquinolones have also been associated with memory loss, psychosis, headaches, depression, anxiety, kidney failure, cardiovascular symptoms, nausea and vomiting, blindness and other health problems
Fluoroquinolones are antibiotics with an attached fluoride molecule, which gives them the ability to penetrate into sensitive tissues like your brain and central nervous system, where they can exert neurotoxic effects
