Fluoroquinolone toxicity

Posted by cbsolomon @cbsolomon, Sep 11 12:52pm

Did anyone on this forum take cipro levaquin or avelox around the time their neuropathy began. If so, you probably suffered an adverse reaction to the drug. These fluoroquinolone antibiotics are well know for causing bad neuropathies, tendon damage and psychiatric issues. Check your medical records.

Have you been diagnosed with neuropathy as a result of fluoroquinolone toxicity?


I was prescribed ciprofloxacin for UTI by a doctor in June 2017 and got neuropathy overnight.
Unfortunately I didn't know the culprit at the time. Had I known I would have atleast discontinued the course in the middle. Although I was diagnosed one year later for small fiber neuropathy with no reason identified by Mayo Clinic, I am positive that Cipro is the real culprit of my suffering.


Yes instant onset 3rd day of cipro .axonal sensory motor..small fiber and autonomic 8 yrs ago ..healthy n normal to an invalid at 47 .
