Fluoroquinolone antibiotics have been used for years to treat infections, but growing evidence shows these drugs can result in serious and occasionally irreversible adverse effects. The U.S. Food and Drug Administration (FDA) has issued several warning updates about these medications, and many injured patients have filed legal claims as a result.
Suppose you live in Tulsa or anywhere in Oklahoma and suffer complications after taking antibiotics like Cipro or Levaquin. In that case, this guide explains what you need to know and what your options may be.
Fluoroquinolones are a class of strong antibiotics prescribed to treat bacterial infections. Doctors often recommend them for conditions like urinary tract infections (UTIs), bronchitis, sinus infections, and pneumonia.
Some of the most commonly prescribed fluoroquinolones include:
While these drugs can be effective for serious infections, their risks have become more apparent in recent years. The FDA has warned that these antibiotics should only be used when no safer alternatives are available.
FDA concluded that disabling side effects generally outweigh benefits for uncomplicated infections
Over time, the FDA has updated its safety labels for fluoroquinolones as more data on side effects emerged.
Here’s a breakdown of the FDA’s warning history:
Year | FDA Action | Key Warning | Health Risk Highlighted |
| 2008 | Boxed warning | Tendinitis, tendon rupture | Achilles tendon tearing |
| 2011 | Label update | Myasthenia gravis worsened | Exacerbation of muscle weakness |
| 2013 | Label update | Permanent peripheral neuropathy | Nerve damage in limbs |
| 2016 | Widespread boxed warning | Disabling effects (tendons, CNS) | Combined serious side effects |
| 2018 | Label update | Aortic aneurysm/dissection risk | Rare but fatal cardiovascular events |
The FDA has highlighted several serious risks tied to these antibiotics. Some of the most commonly reported include:
Fluoroquinolones can damage the connective tissues in your body, especially tendons. The Achilles tendon is particularly at risk. Patients may feel sudden pain, swelling, or difficulty walking. These injuries can take months to heal and may require surgery.
Peripheral neuropathy affects the nerves in your arms, hands, legs, and feet. Symptoms often include tingling, numbness, weakness, or burning sensations. For some people, these effects never go away.
Patients with a history of myasthenia gravis may find that fluoroquinolones worsen their condition. Muscle weakness may become more severe and progress rapidly.
Although rare, some studies link fluoroquinolones to an increased risk of aortic aneurysm or dissection, particularly in older adults or people with heart conditions. These are medical emergencies that can be fatal.
Some patients have reported confusion, hallucinations, agitation, or even seizures while using these medications.
Because of the severity of these side effects, Drug producers have been the target of thousands of lawsuits. Many claims allege that companies failed to warn doctors and patients about the full scope of the risks.
FDA concluded that the risk of these serious side effects generally outweighs the benefits of fluoroquinolones for uncomplicated infections.
Legal claims have focused on:
In 2015, multiple fluoroquinolone cases were combined into a multidistrict litigation (MDL) focused on nerve damage. Although not all cases resulted in settlements, the litigation brought national attention to these risks.
In Oklahoma, drug injury cases fall under product liability law. This means manufacturers can be held responsible if a product they sold was defective or dangerous. Victims generally have two years from the date they discovered the injury to file a claim.

They can cause tendon ruptures, nerve damage, confusion, hallucinations, and worsen conditions like myasthenia gravis. In rare cases, they may lead to fatal heart complications such as aortic dissection or aneurysm.
The FDA first issued a boxed warning in 2008. Updates followed in 2011, 2013, 2016, and 2018 to include risks such as nerve damage and heart problems. The most recent warnings limit their use to severe infections only.
