The Avelox injury case attorneys at the Drug Law Center are currently investigating and evaluating cases involving the antibiotic side effects, injuries, and complications.


Avelox Drug RecallAvelox (moxifloxacin) is a popular quinolone antibiotic medication used to treat bacterial infections of the stomach, lungs, sinuses, and skin. Doctors also prescribe the medication to prevent or treat the plague because it is highly effective at killing bacteria, which is often the root cause of most infections. In addition, the medication is prescribed in the treatment of infection of the sinuses, pneumonia, and chronic inflammation of the airways. However, for decades, research scientists, doctors, the CDC (Centers for Disease Control and Prevention) and the FDA (Food and Drug Administration) have known that fluoroquinolone antibiotics can cause severe disabling adverse reactions and side effects. The federal agencies recommend prescribing Avelox only when safer antibiotics are not effective.

The History of Avelox

Avelox (moxifloxacin) is a fourth-generation antibiotic medication prescribed by doctors to treat a variety of bacterial infections of the stomach, sinuses, lungs, or skin. The popular antibiotic drug, manufactured by Merck & Company, was first approved by the Food and Drug Administration in 1999 and quickly brought to the medical marketplace to generate billions of dollars in sales since it was first made available.

While effective at treating infections, Avelox can cause serious, debilitating side effects including the tearing or swelling of a tendon, including the Achilles tendon. Many of these severe conditions are irreversible. Because of that, doctors often recommend or prescribe other antibiotics to their patients, especially to those who are at risk including individuals who are 60 years and older and 17 years and younger.

However, those suffering acute bacterial sinusitis and acute bacterial exacerbation of chronic bronchitis usually have no alternative treatment available to improve their health. These patients must decide if the benefits of taking the medication outweigh the serious, debilitating, and possibly permanent, side effects they are likely to experience.

Who Should Avoid Taking Avelox?

Any individual having some type of allergic reaction or adverse event during or after taking Avelox or its generic form moxifloxacin should immediately contact their doctor for care. This includes those who are feeling faint, dizzy, sudden pain, or noticeable tenderness, swelling or stiffness of muscles. Individuals who had any of the following conditions current or in the past should discuss their medical history with a physician to determine whether to take Avelox.

Additionally, any individual with a history of hypersensitivity to Avelox, its generic version moxifloxacin, or any medication in the antibacterial quinolone class should avoid taking the drug. Any type of adverse reaction has the potential of causing a life-threatening condition especially if it involves anaphylaxis shock

Avelox Side Effects

Moxifloxacin and other quinolone antibiotics are known to cause serious and potentially permanent damage to the body’s tendons including ruptured tendons and tendonitis.

In addition, the drug can also cause significant nerve problems (peripheral neuropathy) in the legs and arms and damage to the nervous system. More serious Avalon side effects that typically require immediate medical attention include:

November 2015 – The JAMA internal medicine publication released a study that revealed help fluoroquinolone antibiotic medications can cause the enlargement of aortas. The case study involved nearly 1500 patients used as a comparison against nearly 150,000 patients in a controlled group who had all been hospitalized with aortic dissection and aortic aneurysm problems.

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

2001 – The Annals of Pharmacotherapy published results of the study that first linked long-term, severe nerve damage to taking fluoroquinolone antibiotic medications. The study reveals severe damage to the peripheral nervous system. Authors of the study stated that many of the side effects developed quickly where patients begin suffering adverse effects and reactions in as little as one day after beginning treatment (33% of the time).

Some patients experienced side effects within the first 72 hours (58% of the time) and after 7 days (84% of the time). More than 7 out of every 10 patients experienced persisting symptoms that lasted for at least 3 months and some experienced symptoms more than a year later.

In 2015, recent reports revealed that a 36-year-old plaintiff experienced severe pain in his eyes that led to an impairment of his vision.

Many of the symptoms appeared within two weeks after starting a course of the quinolone antibiotic Avelox. Even though he stopped taking the medication, his vision continued to deteriorate. Over time, his doctors diagnosed him with having pigment dispersion that eventually led to concave irises. The authors of the report noted there was a direct correlation between taking fluoroquinolone medications and suffering eye injuries.

Avelox Injury Lawsuits

Many injured patients have filed Avelox injury lawsuits against Merck & Co. after being harmed by taking their fluoroquinolone class antibiotic. The plaintiffs are seeking financial recompense for their damages including nerve damage, peripheral neuropathy, aortic aneurysms, and other serious problems. All drug makers of quinolone drugs are settling cases out of court to avoid a jury trial.

  • March 2017 – Ten bellwether cases involving product liability claims filed by plaintiffs against the pharmaceutical manufacturers of Avelox, Cipro and Levaquin will be heard soon in US District Court for the District of Minnesota. The bellwether cases will help consolidate rulings and provide access to resources for the more than 735 lawsuits that are currently pending in a floor quinolone MDL (multidistrict litigation) case.
  • August 2016 – An Oklahoma couple is claiming that Avelox is defective, and cause serious nerve damage. As a result, the plaintiffs are filing an Avelox lawsuit against the drug maker Merck & company over their failure to warn them of the potential dangers side effects. Lawsuit documents reveal that the husband was prescribed Avelox in 2008 which he took under the direction of his physician. Soon afterwards the plaintiff started experiencing debilitating severe symptoms.A follow-up visit with his doctor determined he was suffering from peripheral neuropathy, a serious lifelong condition where the nerves in the body are damaged. The couple’s attorneys are saying that the husband’s injuries were the direct cause of taking Avelox, a fluoroquinolone antibiotic medication doctors prescribed to treat bacterial infections. The attorneys have built the plaintiff’s case on the concealment of information, alleging that Merck and Company was aware, or should have been aware, the potential serious side effects of Avelox that had been known for some time in the medical marketplace.
  • December 2014 – Merck & Company and Bayer Healthcare, Inc. are facing one more Avelox peripheral neuropathy lawsuit, this time filed in the US District Court for the District of Columbia by a patient who suffered permanent peripheral neuropathy after taking the brand-name Avelox antibiotic medication. The plaintiff claims she was prescribed Avelox by her physician in 2013 to be taken over a 10-day period. However, on the fourth day, she claims that the medication was making her weakened and pain. At that time, her doctors took her off of the fluoroquinolone antibiotic. Even so, her symptoms continued.Lawsuit documents reveal that her attorneys have built the case on numerous studies including one that “noted in particular the presence of severe and/or persistent nerve problems. Over one-half of the patients surveyed in the study said their symptoms lasted for more than a year.” Lawyers representing the plaintiff have built the case on the pharmaceutical companies’ failure to warn, breach of implied and express warranty, negligence, negligent misrepresentation, fraud, and other grievances.
  • April 2015 – Merck & Company, Inc. and Bayer Healthcare Pharmaceuticals Inc. are facing another Avelox peripheral neuropathy lawsuit, this time filed by a South Carolina plaintiff alleging her nerve damage was caused by the popular fluoroquinolone prescription antibiotic. The plaintiff claims her doctors prescribed the quinolone antibiotic medication in 2013 to be taken over a seven-day course of treatments. The plaintiff claims that at this time she developed antibiotic -related side effects including peripheral neuropathy.Lawsuit documents reveal that she continues to suffer serious and long-lasting peripheral nerve damage even though she no longer takes the Avelox (moxifloxacin) prescription medication. Her attorneys have written that “this is an action for damages suffered by the plaintiff as a direct and proximate result of defendants’’’ negligent in wrongful conduct in connection with the design, development, manufacture, testing, packaging, promoting, marketing, advertising, distribution, labeling, and/or sale of the pharmaceutical drug Avelox, also known as moxifloxacin.”The attorneys working on behalf of the plaintiff have made a variety of allegations against the pharmaceutical companies that make Avelox, and built their case on strict liability, negligence, failure to warn, fraud, breach of implied and expressed warranty, misrepresentation, negligent misrepresentation, unjust enrichment, negligent infliction of emotional distress, and punitive damages.
