Cipro is a fluoroquinolone antibiotic indicated to treat various types of bacterial infections. However, this class of drugs has been linked to peripheral neuropathy and several other adverse side effects which range from mild to life-threatening. In fact, studies show that about 9% of Cipro patients experience side effects, and the likelihood of suffering  a complication increases the longer Cipro is taken.

Common Cipro Side Effects

Common side effects of Cipro include diarrhea, dizziness, drowsiness, headache, stomach upset, abdominal pain, nausea/vomiting, blurred vision, nervousness, anxiety, agitation, sleep problems (insomnia or nightmares), and rash. While these issues are generally mild, and will resolve once treatment with Cipro ends, other side effects associated with the drug can be debilitating and even life threatening.

FDA Flags Potentially Permanent Cipro Side Effects

In May 2015, the U.S. Food & Drug Administration (FDA) updated the Black Box Warning on the Cipro label to state that the risks associated with the antibiotic outweighed its benefits for patients with acute sinusitis, acute bronchitis, and uncomplicated urinary tract infections who have other treatment options. According to the FDA, Cipro side effects could include serious complications involving the tendons, muscles, joints, nerves, and central nervous system. These problems can occur simultaneously, and they may become permanent.

Cipro and Peripheral Neuropathy

Peripheral neuropathy and permanent nerve damage have been reported among hundreds of patients using Cipro and other fluoroquinolone antibiotics. In some of these patients, debilitating nerve damage has persisted for years after treatment with the drug was ended. While information about this potential Cipro side effect was added to the drug’s label in 2004, the label was revised in 2013 after the FDA determined that it did not adequately characterize the possibility of rapid symptom onset and the potential for permanence.

Cipro Aortic Injuries

Studies published in 2015 suggested that Levaquin side effects could include with an increased risk of a life-threatening aortic dissection and aortic aneurysm. The first, which appeared in JAMA: Internal Medicine  in October 2015, suggested that the use of fluoroquinolones was associated with an approximately 2-fold increase for these complications. A month later, a report in BMJ: Open linked the drugs to a 3-fold increased risk of aortic aneurysm.

Cipro and Tendon Ruptures

In 2008, a Black Box Warning was added to the Cipro label about the potential for serious tendon ruptures, including ruptures of the Achilles tendon, and tendinitis. Patients most at risk for these painful and potentially debilitating complications include those over age 60, kidney, heart, and lung transplant recipients, and patients undergoing concomitant steroid therapy.
