Fluoroquinolones and Aortic Pathology

The US Food and Drug Administration (FDA) recently released another warning for fluoroquinolones, this time regarding aortic dissection and aneurysm.  We review the evidence behind this warning, including the following studies: Lee CC  Risk of Aortic Dissection and Aortic Aneurysm in Patients Taking Oral Fluoroquinolone. JAMA Intern Med. 2015;175(11):1839-47. Lee CC Oral Fluoroquinolone and the Risk of Aortic Dissection. J Am Coll Cardiol. 2018;72(12):1369-1378. Pasternak B Fluoroquinolone use and risk of aortic aneurysm and dissection: nationwide cohort study. BMJ. 2018;360:k678. We then review the ACEP clinical policy on aortic dissection covering risk scores, d-dimers, and management of aortic dissection Thanks for listening! Jeremy Faust and Lauren Westafer
