Cipro Aortic Aneurysm & Dissection Side Effects

Cipro is among the most-prescribed antibiotics in the United States. It is often used to treat common illnesses like bronchitis, sinus infections and urinary tract infections.

Cipro belongs to a class of drugs called fluoroquinolones. After the first of these medications were approved by the Food and Drug Administration in the late 1980s, they quickly became the highest-selling antibiotics in the country, climbing from 7 million prescriptions in 1995 to 22 million prescriptions in 2002. Today, more than 26 million people are prescribed a fluoroquinolone antibiotic in the United States each year.

Though Cipro is necessary and can be life-saving in many cases, it is often overprescribed and carries the risk of serious, sometimes life-altering side effects. Recent studies linked the drug to damage in the lining of the aorta, the body’s main blood vessel, suggesting it can cause tears to the aorta, called dissection, or bulging in the aorta, called an aneurysm. Both of these conditions can be fatal if left untreated.

Individuals harmed by Cipro may be able to seek settlements in the form of a Cipro Lawsuit.

Studies link Cipro to Aortic Aneurysm, Dissection

The aorta is the body’s main artery, responsible for carrying oxygenated blood to all parts of the body except the lungs. Damage to the aorta can cause serious, life-threatening complications, including heart attacks, strokes and even death.

Cipro has been linked to two types of damages to the aorta: dissection, or tears to the vessel, and aneurysm, or rupture of the vessel.

Researchers suggest Cipro affects the collagen in the body, specifically type I and type III. Both of these types of collagen make up the majority of the lining of the aorta.

Two recent studies published in the November 2015 editions of JAMA Internal Medicine and BMJ linked Cipro to these risks.

JAMA study

The JAMA Internal Medicine study found patients taking Cipro, or another fluoroquinolone antibiotic, in the last 60 days were at a two-fold increased risk for aortic aneurysm or dissection.

Patients taking the antibiotics in the past 61 days to one year were also at an increased risk, though their risk was slightly lower than current users.

BMJ study

The BMJ study found patients taking Cipro, or other fluoroquinolone antibiotics, were at a nearly three-fold increased risk of aortic aneurysm or dissection. The study, which looked at 1.7 million older adults, said most patients who developed an aortic aneurysm or dissection did so after about 20 days of taking the medication.

According to the study authors:

“Reducing unnecessary fluoroquinolone treatments or prolonged treatment courses might have possibly prevented more than 200 aortic aneurysms in this population.”

Cipro Aortic Aneurysm and Dissection Problems

Aortic aneurysm and dissection are potentially life-threatening side effects of the popular antibiotic Cipro. Both conditions can be fatal if not treated promptly.

Aortic Aneurysm

An aortic aneurysm is an abnormal bulge in the wall of the aorta. When a weak area in the aorta exists, it can allow the pressure within the artery to push outward and create a bulge or ballooned area. When an aneurysm ruptures it is considered a catastrophic, life-threatening event.

Aneurysms can occur in any blood vessel in the body, but most often occur in the aorta. The two most common areas in the aorta to form an aneurysm are in the abdomen and the chest cavity. Aneurysms put people at risk for:

  • Plaque formation in the artery at the site of the aneurysm
  • Blood clots
  • Increased size of aneurysm, causing it to press on another organ causing pain
  • Rupture, due to weakening of the artery walls


Aortic aneurysms are not often accompanied by symptoms. When they are present, symptoms can include:

  • Tearing pain in the chest, abdomen, or middle of the back between the shoulder blades
  • Aneurysms in the chest cavity can cause shortness of breath, hoarseness, cough and difficulty swallowing
  • A rupture can cause loss of consciousness, stroke, shock or heart attack

What is Aortic Dissection?

Aortic dissection is a rare, but often fatal condition that occurs when the inner lining of the aorta tears. When it tears, blood surges through the opening, causing the inner and middle layers of the aorta to separate, or dissect. If the dissection ruptures, it can be fatal.


Symptoms of aortic dissection can mimic those of other diseases. This can often delay diagnosis. An aortic dissection that is caught early and treated promptly significantly improves a person’s chances of survival.

Symptoms of an aortic dissection include:

  • Sudden, severe chest or upper back pain
  • Loss of consciousness
  • Shortness of breath
  • Sudden difficulty speaking, loss of vision, weakness or paralysis on one side of the body
  • Weak pulse in one arm compared to the other

Cipro’s Black Box Warning

In 2008, the FDA required the maker of Cipro, Bayer Healthcare, and other fluoroquinolone antibiotics to include a black box warning on the drug’s label, warning patients of the risk of tendon rupture.

In May 2016, the FDA said it would strengthen that black box warning to say the side effects of Cipro and other fluoroquinolones generally do not outweigh the benefits for patients with sinus infections, bronchitis or uncomplicated urinary tract infections who have other treatment options.

According to the FDA’s May 12, 2016 safety announcement:

“… fluoroquinolones are associated with disabling and potentially permanent, serious side effects that can occur together. These side effects can involve the tendons, muscles, joints, nerves and central nervous system.”

Cipro’s black box warning highlights other side effects associated with the popular antibiotic medications, including damage to tendons or tendon rupture and nerve damage called peripheral neuropathy.

Tendon rupture

Cipro increases a person’s risk for tendon damage or rupture. While this can affect any tendon in the body, it most often occurs in the Achilles tendon. The FDA’s 2008 black box warning strengthened an existing warning on the drug’s label.

The agency said the risk for tendon damage or rupture is greater for those over 60, who are using steroidal medications, or who have had a lung, kidney or heart transplant.

Symptoms of a damaged or ruptured tendon include:

  • Pain, swelling or inflammation
  • A snap or pop in the tendon area
  • Bruising right after injury in a tendon area
  • Inability to move the affected area or bear weight

Peripheral neuropathy

In 2013, the FDA issued a safety communication regarding the risk of peripheral neuropathy while taking Cipro and other fluoroquinolones.

Peripheral neuropathy is severe nerve damage occurring in the arms or legs. The agency warned it could occur at any time while taking Cipro and could last for days or months after stopping the medication. For some people the symptoms could be permanent, the agency would later warn.

Symptoms of peripheral neuropathy include:

  • Pain
  • Burning
  • Tingling
  • Numbness
  • Weakness
  • Change in sensation to light touch, pain or temperature, of sense of body position

Other side effects

In addition to those mentioned above, Cipro carries the risk of other side effects, including:

  • Headaches
  • Seizures
  • Hallucinations
  • Abnormal heart rhythm
  • Skin rash
  • Stomach problems

Cipro Lawsuits

Previous class action and individual lawsuits have been filed against the makers of some fluoroquinolone antibiotics due to the drugs’ possible side effects of tendon rupture and peripheral neuropathy.

With recent studies linking the antibiotic medications to aortic aneurysms and dissections, new lawsuits are being filed in 2016 by those harmed by the popular drugs.

National Injury Help is currently investigating cases for a potential lawsuit against the makers of Cipro, pharmaceutical giant Bayer Healthcare.

Three recent questions about Cipro lawsuits people are asking us.

How much can you sue for a Cipro lawsuit?

How much compensation would I get from a Cipro lawsuit?

How much is the settlements from a Cipro lawsuit?

The answer to these questions can be difficult to predict, as the possible MDL for this hasn’t started yet. There is still time for join in this Cipro lawsuit, but there are statutes of limitations that apply.

Some of the past defective drug lawsuits have had millions of dollars in a compensation fund, and then that is divided up between all who have joined the lawsuit. Example: $100,000,000 in a settlement fund that would serve 1,000 victims would be $100,000 per person. This is only an example and does not represent what may happen for Cipro.

Other lawsuits are possibly forming against the makers of other popular fluoroquinolone antibiotics, including Levaquin.
