FDA Warns – Systematic use of Cipro, Levaquin and other antibiotics can lead to disabling and serious side effects
Antibiotics are a class of drugs that can effectively stop dangerous bacterial infections in their tracks by eliminating the growth of bacteria or killing it all together.
However, the FDA is now warning that in the case of fluoroquinolones (FQs) antibiotics, these drugs may carry unwanted and serious side effects that were not previously warned about.
In November 2015, an FDA committee advisory meeting heard the testimonies of more than 30 members of the public regarding the life-altering injuries they have lived with and they believe were linked to their FQ treatment.
Although the FDA advisory panel overwhelmingly agreed that there needed to be changes made to the FQ labels and recommended as much to the FDA, it took until May 2016 for the FDA to take action on warning the public about the dangers of fluoroquinolones antibiotic use.
FDA Warning
According to the FDA Safety Communication systematic use of fluoroquinolones (such as Cipro, Levaquin, Avelox, Floxin and Factive) is 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.
While the FDA Advisory recommended the use of the term “fluoroquinolones associated disability” (or FQAD) to describe the potentially permanent serious side effects that can occur together, the FDA stopped short of naming this disability.
Despite the lack of a name, these serious side effects will now be the subject of a strengthened warning on the fluoroquinolone family of antibiotics, which includes such drugs as Levaquin, Cipro, Avelox, Factive and Floxin.
These labels will now include a “limitation of use” so that it is no longer appropriate for medical professionals to prescribe one of these antibiotics to treat sinusitis, bronchitis or an uncomplicated urinary tract infection.
According to the FDA, serious side effects associated with these popular antibacterial drugs outweigh the benefits for patients with sinusitis, bronchitis, and uncomplicated urinary tract infections who have other treatment options.
Fluoroquinolones Overprescribed
Fluoroquinolones (FQs) have been used for over 20 years and critics note that they are overprescribed.
According to the CDC, FQs are the fourth-most prescribed antibiotic nationwide – prescribed to 33 million Americans in 2013 alone.
In the past few years, advocates have worked hard to get word out about the serious side effects from FQ toxicity.
These individuals, many of whom are currently suffering from these life-altering side effects, refer to these collective injuries as “floxing” and “antibiotic toxicity.”
They have set up Facebook pages and website in an effort to get word out through social media.
The FDA warning and label change will be helpful in these efforts to get word out to the public but also to get word to health care professionals who often come up with no specific diagnosis for the constellation of symptoms from these antibiotics.
Fluoroquinolone Side Effects
Aortic Aneurysm
An aortic aneurysm is a lump in the aorta which is the body’s main artery.
The aorta carries oxygen-rich blood out from the heart to the other areas of the body.
The bulging section with the aneurysm is overstretched and weak which can lead it to burst.
A burst in the aorta can cause serious bleeding which may quickly lead to death.
Aortic Dissection
Aortic dissection is a tear in the inner layer of the aorta.
The aorta is the main blood vessel branching off of the heart which carries oxygen-rich blood throughout the body.
When dissection occurs, blood surges through the tear causing the inner layers of the aorta to break apart (dissect).
If this rupture penetrates the outer wall of the aorta, the outcome of aortic dissection is often fatal.
A Constellation of Disorders
Symptoms affecting the tendons, muscles, joints, nerves and/or central nervous system.

Peripheral Neuropathy
Peripheral neuropathy is the outcome of damage to peripheral nerves.
Side effects are often weakness, pain, and numbness usually in your hands and feet but may also affect other areas.
Many people diagnosed with peripheral neuropathy will describe the pain as stabbing, tingling, or burning.
Peripheral neuropathy can result from toxins and is currently being linked to fluoroquinolone antibiotics.
Cardiac Valvulopathy
Cardiac Valvulopathy is a condition in which the heart valve becomes inflamed and stiff.
A heart valve must remain closed during a period in the blood flow cycle.
When the blood is not retained adequately in the valve during this cycle, the blood can be returned to the previous chamber in the heart.
This “valvulopathy” causes damage in the heart which for many now being linked to the use of fluoroquinolone antibiotics.
Antibiotic Lawsuits Moving Forward
Lawsuits on behalf of individuals living with these serious injuries are being filed against the manufacturers of Levaquin, Cipro, Avelox, Factive and Floxin alleging that these drugs put individuals at risk of injury.
According to these antibiotic lawsuits, the manufacturers did not properly warn of the risk of these popular antibiotics.
Furthermore, many of the individuals injured by Cipro, Levaquin or one of the other fluoroquinolones was prescribed the drug for the treatment of illnesses that were likely to be resolved on its own such as a urinary tract infection, sinusitis, bronchitis or other illnesses.
