Avelox Aortic Aneurysm Lawsuit

Side effects of Avelox may include abdominal aortic aneurysm, a life-threatening condition that occurs when the aorta becomes abnormally enlarged.

Side effects of the antibiotic medication Avelox (generic: moxifloxacin) may include abdominal aortic aneurysm (AAA), a life-threatening condition that occurs when the aorta — the major blood vessel that supplies blood to the body — becomes abnormally enlarged.

Avelox belongs to a class of antibiotic medications called fluoroquinolones that are used to treat bacterial infections of the skin, sinuses, lungs or stomach. Fluoroquinolones work by inhibiting bacterial DNA replication, thereby treating the infection. Avelox is made by Merck & Co., and was approved by the U.S. Food & Drug Administration (FDA) in December 1999.

What’s the Problem?

A study published in JAMA Internal Medicine in November 2015 found that fluoroquinolone antibiotics may cause the aorta to become enlarged. The researchers looked at 1,477 case patients and compared them against a control group of 147,700, from Taiwan’s National Health Insurance Research Database (NHIRD) from Jan. 2000-Dec. 2011. All case patients were hospitalized for aortic aneurysm or dissection.

The findings suggest that current fluoroquinolone use increased the risk for aortic aneurysm by more than double. Past use increased the risk by nearly 50%.

“Use of fluoroquinolones was associated with an increased risk of aortic aneurysm and dissection,” the study’s authors concluded. “While these were rare events, physicians should be aware of this possible drug safety risk associated with fluoroquinolone therapy.”

What is an Aortic Aneurysm?

An aortic aneurysm is a bulge or “ballooning” in the wall of the aorta. There are 2 types of aortic aneurysm:

  • Thoracic Aortic Aneurysm (TAA) – Occurs in the part of the aorta running through the chest.
  • Abdominal Aortic aneurysm (AAA) – Occur in the part of the aorta running through the abdomen.

Not all aortic aneurysms are life-threatening; however, if the bulging stretches the artery too far, the vessel may burst, causing the patient to bleed to death.


Symptoms of TAA may include:

  • Pain in the jaw, neck, upper back or chest
  • Coughing, hoarseness or difficulty breathing

Symptoms of an AAA may include:

  • Pulsating enlargement or tender mass felt by a doctor when performing a physical examination
  • Pain in the back, abdomen or groin not relieved with position change or pain medication

Aneurysm Repair

Endovascular abdominal aortic aneurysm repair is a type of surgery used to repair widened areas of the aorta. During the surgery, a small incision is made near the groin to find the femoral artery. Next, a stent and synthetic graft are inserted into the artery. X-rays are used to guide the stent graft up into the aorta where the aneurysm is located. The surgeon will open the stent using a spring-like mechanism and attach it to the walls of the aorta. The aneurysm will eventually shrink around it.
