Antibiotics are life savers. But like all drugs, they have side effects, and some may be dangerous and deadly. This is especially true with a class of drugs called fluoroquinolones that include Levaquin, Cipro, and Avelox.

Over 33 million Americans take one or more of these antibiotics each year, and in 2010, Levaquin was the bestselling antibiotic in the country. There's a good chance that you or a family member has taken one of these potentially harmful drugs within the last year.

Serious questions have been raised about the safety of these medications, most notably Levaquin, since their marketing in 1996. Until recently, the FDA did little to warn doctors and consumers of the possible deadly side-effects. By 2010, Levaquin was involved in over 3,400 lawsuits and possibly 5,000 deaths.

Dangerous Side Effects

According to The Daily Beast:
Warnings surrounding the popular antibiotic Levaquin have been dangerously insufficient. The drug, capable of causing debilitating tendinitis, permanent nerve damage, and even psychosis, is meant to be reserved for severe life-threatening infections.
Unfortunately, many doctors are prescribing fluoroquinolones like Levaquin for non-life threatening conditions such as earaches, bronchitis, sinusitis, and other ailments which could be allowed to resolve on their own or are easily treated with lesser drugs or non-drug remedies. This has led to bacterial resistance and serious, possibly life-threatening side-effects in people who should not be taking the drug for less severe conditions.

Thousands of people have reported ill effects from taking Levaquin and have chronicled the adverse effects of this class of drugs, which include paralysis, excruciating joint pain, tendon ruptures, difficulty breathing, exhaustion, neurological damage, dizziness, depression, anxiety, etc.

Here are some typical comments from Levaquin users who experienced adverse effects:

From "Took one pill- then could not walk for months- Was in a wheelchair - extreme pain."

From "I was a healthy, active college student minoring in dance when I took this for a sinus infection. After a few pills it completely destroyed my life...No more than hour of sleep for over a year due to neurological damage that destroyed my sleep cycle."

From "worst stuff I have ever used ended up in the er was so scared, it killed me with back and knee pain could not get out of bed without screaming, never again!"

In 2012, Jane Brody of the New York Times interviewed Dr. Mahyar Etminan, a pharmacological epidemiologist who researched the effects of fluoroquinolones. He found "that the risk of suffering potentially blinding retinal detachment was nearly fivefold higher among current users of fluoroquinolones . . . and [there was] a significantly increased risk of acute kidney failure."

Dissection and Aneurysm

The Journal of the American Medical Association (JAMA) reported in 2015 a two-fold increase in risk of dissection and aneurysm within 60 days of using the fluoroquinolones.

The British Medical Journal (BMJ) also published a comprehensive study of 1.7 million patients in 2015 that chillingly found a three-fold increase in aortic aneurysms:

Lawsuit Against Former FDA Commissioner

Margaret Hamburg

FederalCharges.comhas reported that former FDA Commissioner Margaret Hamburg has been named in a federal lawsuit that alleges she conspired to:
...get a dangerous drug approved (Levaquin) even though it had serious and sometimes deadly side effects. She did this, the lawsuit alleges, to financially benefit the hedge fund her husband ran, which had large stakes in Johnson & Johnson, which makes the drug.
The complaint also alleges that Levaquin is responsible for over 5,000 deaths.

Hamburg's attorneys called the lawsuit "patently false," "defective," and lacking in factual evidence. "We are confident the court will dismiss his claims in their entirety."

Whatever the merits of the lawsuit against Hamburg, it highlights the seriousness of the drug's harmful effects on thousands of people and possible FDA complicity in approving a dangerous and deadly drug.

What Is Being Done?

Levaquin is a powerful drug that has helped countless individuals. But the dark side of Levaquin has been underplayed by the FDA and too nonchalantly used by physicians for ailments that could be improved or cured by less potent drugs. This inappropriate usage has led to serious and life threatening complications for many.

The FDA has known of the problems with Levaquin for some time. In 2006, the Public Citizen Research Group petitioned the FDA to add a black box warning to the label. In 2008, the FDA agreed to add the black box warning for the high risk of tendinitis and tendon rupture. However, no FDA communication to this effect was sent to physicians. Levaquin went on to be the best selling antibiotic in the US by 2010.

Also in 2010, Johnson and Johnson, makers of Levaquin, settled over 800 lawsuits out of 3,400 suits filed charging that patients were not made aware of the dangers involving the drug and paid out $1.8 million to one plaintiff who suffered tendon rupture. reported in 2013 that:
...the FDA released a Safety Communication warning about over-prescribing and said current warnings were not clear enough. Specifically, the agency said "the potential rapid onset and risk of permanence were not adequately described," and the "permanent damage among patients exposed to these medications cannot be calculated.
In 2015, Dr. Charles Bennett, who runs one of the largest pharmaceutical watchdog groups in the country, the Southern Network on Adverse Reactions (SONAR), filed a citizen petition with the FDA regarding fluoroquinolones asking that mitochondrial toxicity and serious psychiatric events be added to the FDA's black box warning.

Bennett has collected "testimony from thousands of patients all across the country, patients who experienced muscle weakness, chronic fatigue, cardiomyopathy, hearing loss, developmental disorders, severe depression or nerve damage after taking Levaquin and related drugs."

Where Do Things Stand Now?

In May of 2016, the FDA finally upgraded its warnings about the use of fluoroquinolones and Levaquin.

Paul Auwaerter, with Medscape Infectious Diseases and the Johns Hopkins University School of Medicine, states that the FDA has recognized the increased risk of fluoroquinolones for Clostridium difficile infection (compared with many other antibiotics), tendinopathy, arthropathy, QT prolongation, retinal issues, and central and peripheral nervous system toxicities.

Auwaerter adds that the FDA now feels that owing to potential irreversible or permanent side effects, these drugs should not be used for first-line treatment for common upper respiratory tract infections such as bronchitis or sinusitis, or for urinary tract infections.

He concludes definitively that "it does not make sense to prescribe these drugs . . . to treat conditions that could be treated with a narrower-spectrum and more targeted drug."

What Should You Do?

Drugs like Levaquin are overprescribed and used inappropriately by many physicians who don't realize their potential hazard. Unfortunately, the onus is on you to protect yourself. Here is what you should consider:
  • Ask your doctor which antibiotic they are prescribing.
  • Fluoroquinolones should be reserved for severe, life-threatening infections.
  • Discuss alternative drugs or treatments with your physician.
  • If you must take the drug for a serious condition, tell your doctor immediately of any symptoms you experience.
  • Read all black box warnings and lists of side effects.
  • Sign up for FDAconsumer drug updates.
You must protect yourselfand your family against the misuse of these powerful drugs. Don't be a victim.
