Despite FDA Warning, Fibromyalgia Risk Similar Between Fluoroquinolones, Other Antibiotics, Study Suggests
The use of oral fluoroquinolones (FQs) poses the same level of fibromyalgia risk as other antibiotics such as amoxicillin and azithromycin, a study suggests. The study, “Oral Fluoroquinolones and Risk of Fibromyalgia,” was published in the British Journal of Clinical Pharmacology. Oral FQs, which are the most prescribed antibiotic, received a black box warning in 2016 from the U.S. Food and Drug Administration. The warning was based on severe side effects reported after the use of FQs that resembled fibromyalgia — widespread amplified pain in the muscles and joints. But the prevalence of this risk has not been quantified in detail. Of significance, respiratory infections, for which FQs might be prescribed, may also lead to fibromyalgia, which could confuse the association between fibromyalgia and FQs. In this study, researchers in Canada aimed to correlate the use of FQs to cases of fibromyalgia that were part of health claims filed between 2006 and 2016. Using a large health claims database in the U.S., PharMetrics Plus, the team identified cases reported as fibromyalgia by a rheumatologist. All FQ prescriptions were identified, and only those individuals whose FQ prescription preceded their fibromyalgia diagnosis entry by three months to a year were included. Patients who were prescribed amoxicillin and azithromycin were also included. Amoxicillin a

    I was floxed by Levaquin. No drs even recognize it. They refuse to even look up that it has a black box warning. I had to stop the medication against my drs orders because he refused to even look up warning. I had all the symptoms. It crippled for a while. I figured it out after researching all the meds I was on, which was only 4. If anybody knows of a dr who at least acknowledges it and lists it in their medical chart please post. If you become disabled from this nasty antibiotic, you basically out of luck because drs refuse to acknowledge it and refuse to even read the black box warning info. I called the company and made them call my dr to educate him. he had me on medication over 45 days. warning says never use more than xxx days. so frustrating.
