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 youre over age 66), and destabilize your blood sugar if youre 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

The US Food and Drug Administration (FDA) recently issued a warning that fluoroquinolone antibiotics, taken by mouth or injection, carry a risk for permanent peripheral neuropathy. The safety announcement states:1
The U.S. Food and Drug Administration (FDA) has required the drug labels and Medication Guides for all fluoroquinolone antibacterial drugs be updated to better describe the serious side effect of peripheral neuropathy.
This serious nerve damage potentially caused by fluoroquinolones may occur soon after these drugs are taken and may be permanent… The topical formulations of fluoroquinolones, applied to the ears or eyes, are not known to be associated with this risk.
Peripheral neuropathy is nerve damage in the arms and/or legs, characterized by pain, burning, tingling, numbness, weakness, or a change in sensation to light touch, pain or temperature, or sense of body position.
This is not the first warning FDA has posted about this family of antibacterial drugs. In 2008, they posted a black box warning about severe tendon damage. Now having the additional warning for severe and sometimes-permanent nerve damage, there should be NO question in your mind about the danger of these drugs, and I strongly recommend avoiding them if at all possible.
Fluoroquinolones, a class of synthetic antibacterial drugs, are the only types that directly inhibit bacterial DNA synthesis. Several drugs in this class have been taken off the market due to their deadly adverse effects, but six of them remain FDA-approved for use in the United States:
Ciprofloxacin (Cipro) Levofloxacin (Levaquin) Gemifloxacin (Factive) Moxifloxacin (Avelox) Norfloxacin (Noroxin) Ofloxacin (Floxin)
Due to their tremendous health risks, fluoroquinolones should be reserved for treating serious bacterial infections that wont respond to any other treatment, when the patient is made fully aware of the potential for serious adverse events. Instead, theyre often inappropriately prescribed for mild conditions like sinus, urinary tract and ear infections.
