PharmTech Followup: Fluoroquinolone Antibiotics

Rockville, MD (Oct. 16)-In July 2008, Pharmaceutical Technology reported that the US Food and Drug Adminstration had asked manufacturers of fluoroquinolone antimicrobial drugs to add a black-box warning label on their products noting the increased risk of tendonitis and tendon rupture with the drug’s use. Also in July, the European Medicines Agency (EMEA) had recommended strengthening the warnings for oral moxifloxacin medicines and concluded that these drugs should only be prescribed to treat acute bacterial sinusitis, acute exacerbation of chronic bronchitis, and community-acquired pneumonia when other antibiotics cannot be used or have failed.

Now, three months later, FDA has completed its labeling updates. The agency posted the new labels on its website last week.
