 +<blockquote>
 +Safety Announcement
 +[12-20-2018] A U.S. Food and Drug Administration (FDA) review found that fluoroquinolone antibiotics can increase the occurrence of rare but serious events of ruptures or tears in the main artery of the body, called the aorta.  These tears, called aortic dissections, or ruptures of an aortic aneurysm can lead to dangerous bleeding or even death.  They can occur with fluoroquinolones for systemic use given by mouth or through an injection.
 +
 +Fluoroquinolones should not be used in patients at increased risk unless there are no other treatment options available.  People at increased risk include those with a history of blockages or aneurysms (abnormal bulges) of the aorta or other blood vessels, high blood pressure, certain genetic disorders that involve blood vessel changes, and the elderly.  We are requiring that a new warning about this risk be added to the prescribing information and patient Medication Guide for all fluoroquinolones.
 +
 +Fluoroquinolone antibiotics are approved to treat certain bacterial infections and have been used for more than 30 years.  They work by killing or stopping the growth of bacteria that can cause illness.  Without treatment, some infections can spread and lead to serious health problems (see List of Currently Available FDA-Approved Systemic Fluoroquinolones).
 +
 +Health care professionals should avoid prescribing fluoroquinolone antibiotics to patients who have an aortic aneurysm or are at risk for an aortic aneurysm, such as patients with peripheral atherosclerotic vascular diseases, hypertension, certain genetic conditions such as Marfan syndrome and Ehlers-Danlos syndrome, and elderly patients.  Prescribe fluoroquinolones to these patients only when no other treatment options are available.  Advise all patients to seek immediate medical treatment for any symptoms associated with aortic aneurysm.  Stop fluoroquinolone treatment immediately if a patient reports side effects suggestive of aortic aneurysm or dissection.
 +
 +Patients should seek medical attention immediately by going to an emergency room or calling 911 if you experience sudden, severe, and constant pain in the stomach, chest or back.  Be aware that symptoms of an aortic aneurysm often do not show up until the aneurysm becomes large or bursts, so report any unusual side effects from taking fluoroquinolones to your health care professional immediately.  Before starting an antibiotic prescription, inform your health care professional if you have a history of aneurysms, blockages or hardening of the arteries, high blood pressure, or genetic conditions such as Marfan syndrome or Ehlers-Danlos syndrome.  If you have been prescribed a fluoroquinolone to treat an infection, do not stop the antibiotic without first talking to your health care professional.
 +
 +We reviewed cases reported to FDA* and four published observational studies1,2,3,4 that showed an increased risk of aortic aneurysm or dissection associated with fluoroquinolone use (see Data Summary).  How some of the studies were designed or carried out, and the ways the data were analyzed could affect the study findings; however, taken together, the results of all four studies provide consistent evidence of an association between fluoroquinolone use and aortic aneurysm or dissection.  The underlying mechanism for this risk cannot be determined from these studies, and the background risk of aortic aneurysm can vary depending on the population.  The background risk has been estimated from nine aortic aneurysm events per 100,000 people per year in the general population to 300 aortic aneurysm events per 100,000 people per year in individuals at highest risk.  Because multiple studies showed higher rates of about twice the risk of aortic aneurysm rupture and dissection in those taking fluoroquinolones, FDA determined the warnings were warranted to alert health care professionals and patients.
 +
 +We communicated safety information associated with fluoroquinolones in July 2018 (significant decreases in blood sugar and certain mental health side effects), July 2016 (disabling side effects of the tendons, muscles, joints, nerves, and central nervous system), May 2016 (restricting use for certain uncomplicated infections), August 2013External Link Disclaimer (peripheral neuropathy), and July 2008External Link Disclaimer (tendinitis and tendon rupture).
 +
 +To help FDA track safety issues with medicines, we urge patients and health care professionals to report side effects involving fluoroquinolones or other medicines to the FDA MedWatch program, using the information in the “Contact FDA” box at the bottom of the page.
 +
 +*The cases were reported to the FDA Adverse Event Reporting System (FAERS). [Which gets only 1% of actual reports!]
