Cipro is an antibiotic manufactured by Bayer Pharmaceuticals. Cipro belongs to the class of medications known as fluoroquinolones, which fight bacteria in the body by stopping the production of essential proteins needed by the bacteria to survive. Although Cipro is used to treat many types of infections, it does not work for viral infections, such as the common cold or flu.

In addition to many common bacterial infections, Cipro has also been approved by the U.S. Food & Drug Administration (FDA) for the treatment of anthrax inhalation. After the U.S. anthrax scare in 2001, the antibiotic was prescribed to thousands of people, especially postal workers, who may have been exposed to mail containing anthrax. Today, the U.S. military stockpiles Cipro in case of another biological disaster of this kind.

Cipro Health Risks

Fluoroquinolones like Cipro are extremely potent, and can kill the “normal flora” – good bacteria – in the digestive tract. This may allow yeast or other unwanted bacteria to grow significantly, resulting in upset stomach, diarrhea, or vomiting. To help avoid this problem, doctors recommend taking Cipro with lots of water.

Cipro and other fluoroquinolones have been linked to a number of serious side effects, some of which can lead to permanent disability, and even death. In May 2016, the labels of these antibiotics were updated with a new Black Box Warning stating that, in most cases, their risks outweighed their benefits in patients with certain uncomplicated infections. The new warning came after an FDA review confirmed that the drugs could cause serious and potentially permanent complications affecting the nerves, muscles, tendons and central nervous system.

Some of potential Cipro side effects include:

Peripheral Neuropathy

In 2001, a study published in the Annals of Pharmacotherapy detailed a45 cases of peripheral neuropathy among people treated with fluoroquinolone antibiotics like Cipro. More than 80 of the cases were described as “severe,” while over half persisted for a year or more. In 2013, all fluoroquinolone labels were updated to included mention of peripheral neuropathy as a potential complication. However, in August 2013, the FDA ordered all fluoroquinolone manufacturers torevise their labels so that information regarding peripheral neuropathy noted the possible rapid onset of the condition, as well as its potential for permanent nerve damage. The agency also asked that language characterizing the disorder as a rare occurrence be removed.

Aortic Aneurysm and Aortic Dissection

Aortic aneurysm and dissection are serious injuries that can lead to death. At least two recent studies have linked the use of fluoroquinolones like Cipro to these dangerous complications. The first was published in October 2015 in JAMA: Internal Medicine and linked the drugs to a 2-fold increased risk for aortic aneurysm and dissection within 60 days of treatment. A month later, Canadian researchers writing in the British Medical Journal reported that patients using fluoroquinolone antibiotics might face a three-fold increase risk of aortic aneurysm.

Tendon Ruptures, Tendinitis

In 2008, the FDA mandated that a Black Box warning be added to the labels of Cipro and similar antibiotics, due to an increased risk of serious tendon injuries, including tendon ruptures (especially affecting the Achilles tendon) and tendinitis.

Injured by Cipro?

Hundreds of lawsuits have been filed by individual who allegedly suffered adverse reactions due to Cipro and other fluoroquinolone antibiotics. You may be entitled to compensation if you or a loved one took Cipro and experienced serious complications, including peripheral neuropathy, permanent nerve damage, or aortic aneurysm/dissection.
