Recent studies have shown that current and past use of fluoroquinolone (flurr-oh-QUINN-a-lones) antibiotics may be associated with an increased risk of serious aortic side effects.

One study showed that adults who had recently taken a fluoroquinolone (FLQ) had a two-fold increased risk to be hospitalized for aortic aneurysm or aortic dissection.

Past use, within the past year, of FLQ antibiotics also showed an increased risk of severe aortic events. Usage of these drugs in the past year showed a lesser but still increased risk.


Fluoroquinolone antibiotics including Cipro, Levaquin, and Avelox have been linked to aortic aneurysms and aortic dissections – two potentially fatal side effects that have many in the medical community alarmed. With over 25 million prescriptions written for FLQs each year, and a scientific connection to serious side effects, and has led to a number of lawsuits against the manufacturers of these drugs for aortic injuries.

What is an Aortic Aneurysm

An aortic aneurysm occurs when the aorta bulges, balloons or enlarges. This severely weakens that section of the aorta and can cause it to burst, leading to serious internal bleeding.

What is an Aortic Dissection

An aortic dissection occurs when a tear develops in the aorta, weakening the walls of the aorta and potentially leading to leaks or ruptures.

An estimated 15,000 Americans die each year from aortic aneurysms – a number that has risen in over the last several decades. Several factors may contribute to the increased number of aortic aneurysms, including the increased use of fluoroquinolone antibiotics.

The aorta is the largest blood vessel in the body, branching off of the heart and providing blood to much of the body. Aortic side effects are very serious and can often be fatal. As the aorta weakens or degrades the risk of leaking or rupturing increases.

If the aorta ruptures completely a person can die from internal bleeding or from their body being deprived of the blood that would be normally be supplied by the aorta.


FLQs have been associated with collagen-related disorders such as tendon rupture, other tendon issues, and retinal detachment. The FDA announced in 2008 that it would require a black-box warning on all FLQ antibiotic packaging.

Fluoroquinolone’s impact on collagen may be the cause the serious aortic side effects. Like tendons, the aortic walls also contain collagen and can rupture or fail. When FLQs degrade the body’s collagen, they can also cause or contribute to aortic aneurysm or aortic dissection.


Fluoroquinolones are the most used types of antibiotics in the United States with over 25 million prescriptions written each year. The wide range of applications for these antibiotics, including respiratory and urinary tract infections, makes them a popular choice for prescribing doctors.

Cipro, Levaquin and Avelox aren’t the only approved fluoroquinolone antibiotics. There are 6 FLQs approved for use in the United States, although these three drugs account for the vast majority of FLQ prescriptions.

Lawsuits are being filed across the United States over serious aortic side effects from fluoroquinolones. The lawsuits allege that:

  • Doctors and patients were not provided with the appropriate warning about the risk of aortic aneurysm and aortic dissection from FLQs
  • The drug manufacturers were negligent when they promoted, distributed, marketed and labeled fluoroquinolone products
